HISTORY OF THE INVENTION
1. Field of the invention 5 The invention relates to an orthodontic bracket system, more specifically to a self-ligating bracket that can include a sliding clip with shape memory.
2. Brief description related to art Orthodontic treatments typically involve dental work 10 to correct irregularities of the teeth or the relationship of the teeth to the surrounding anatomy. Irregularities can involve malocclusions with varying degrees of severity. Examples of malocclusions include, space irregularities, such as crowding or excessive diastema, overbite irregularities and 15 deep bite irregularities. The list of treatments for exemplified irregularities, as well as others, typically involves the installation of appliances or mechanical aids necessary for the repositioning of teeth within a correct or appropriate orthodontic alignment. Conventionally, braces include orthodontic brackets 20 designed to be placed either on the lingual or buccal surface of a tooth. Generally, brackets have channels where flexible arches are placed, although resilient. Each bracket is fixed to the appropriate tooth surface so that the groove is oriented to facilitate the positioning of the arch within it. Brackets can be oriented in different ways where the 25 arches extend orthogonally or parallel to the long axis of the tooth root. Since Dr. Edward Hartley Angle patented the Edgewise bracket in the 1920s, the biomechanical function of the orthodontic bracket remains essentially unchanged. Despite significant improvements in design, high technology in manufacturing processes and the development of new materials 30 since the Edgewise bracket was patented, the concept of movement with the control of teeth in the three dimensions of the space remains the same. The quality and development of the materials associated with the concepts of light biological forces provided orthodontists with a new relationship regarding the preservation of the integrity of the periodontal ligament in the treatment of 35 malocclusions. The geometric configuration of the bracket incorporates a horizontal channel transversely positioned in relation to the face of the bracket with a pair of parallel walls positioned perpendicular to the bottom of the channel, which defines a rectangular configuration of the channel in a cross section. The 5 10 15 20 25 30 35 40 walls parallel to the channel are called mooring fins or extensions projected vertically and upwards in relation to the tooth surface.
An arch positioned inside the channel can present varied dimensions and cross sections (ex round and rectangular) from which the professional can choose an arch based on the patient's intention to use or need. More precisely, the arch configuration can be chosen based on the treatment phase and the extent of movement planned by the orthodontist. For example, the bow is known to be made with a certain material from a metal, a metallic material and or an elastic memory material that can be bent or twisted before being installed inside the channel. The memory or recovery force exerted by an arch in the brackets helps to move the teeth to their desired alignment.
Orthodontic brackets have different characteristics determined statistically by values such as torque, angulation, in and out, against rotation, extrusions inherent to the placement of the channel in a tooth based on the tooth, in which the orthodontist has the option to individualize the set of brackets to be used in the treatment according to the facial pattern and the ideal positioning of the tooth in relation to the inclination and angulation in this way, minimizing the need for folds and adjustments in the arches. In orthodontics, this treatment methodology is conventionally known as the "Straight Arch Device", in a conception that happened in the 1970s and is commonly attributed to Dr. Lawrence Andrews.
In the 1930s, self-ligating brackets became commercially available. The main feature of such brackets in the 1930s was the ease with which the bows were exchanged, saving the Orthodontist hours of sitting. In the 70s, numerous studies are researching friction within the channel, which led to the appearance of a new generation of self-ligating brackets which were based on the concept of low friction and sliding mechanics. Consequently, a proposition was developed where low friction and force mechanics were used to move teeth with orthodontic brackets without bandages.
The use of elastomeric or metallic bandages associated with conventional brackets presents new difficulties and concerns. For example, the placement of metal bandages is a time-consuming operation and can lead to repetitive movements injuries to orthodontics professionals.
In addition, there are considerable costs associated with the specific procedures required when using a set of sterile instruments dedicated to placing the bracket on the tooth. Elastomeric bandages, despite the ease of placement around the bracket compared to previously used bandages, deteriorate reasonably quickly inside the patient's mouth, absorb water and accumulate excess plaque, thus leading to an undesirable condition of the periodontium such as inflammation. Both of the aforementioned connection methods, the use of steel bandages or elastomeric ligation, suffer the effects of high friction forces being applied to the bracket / arc torque once the Normal forces are applied, which press the arches against the bottom of the channel. , preventing the work energy that is carried by the arc to be applied to tooth movement. The restrictive force, regardless of the treatment methodology or technique used, results in a greater frequency in which the arcs must be exchanged, as well as higher levels of forces are applied by the arc to the bracket. 10 In the 1980s, the aforementioned concept of low friction / strength gained momentum with the development of new alloys used in the manufacture of bows. The metal alloys were developed to have a low force module calibrated to the needs of self-ligating brackets. The reduction of friction allowed the teeth to slide more easily during certain stages of treatment with low force modules, contributing to faster treatments that required less visits to the orthodontist and less pain experienced by the patient.
A difficult task in choosing the arch used for tooth movement is the predictability of the effective force that will be transmitted by the arch to the tooth. 20 Restrictive forces of elastomeric “O” or steel bandages are variables that lead to indeterminate effective forces used in tooth movement. Sometimes, steel or elastomeric bandages deflect the arches in addition to their elastic properties, resulting in a permanent crease of the arch or plastically deforming the arch in a way that results in a permanent bend.
Research on self-ligating brackets using high-tech test equipment determines that 6% to 10% of the force applied to the tooth is lost due to friction.
In this way, 90% of the applied force becomes an effective force to move teeth.
Although friction reduction is desirable, there are occasions when more friction is needed, such as in the final stages of treatment when consolidation of the arch shape in the three planes of the space is required to stabilize the result obtained and the shape of the dental arch. Clinical modifications or the placement of 35 more conventional brackets become a requirement as treatment progresses resulting in an increase in material costs and time-consuming procedures in the office.
On the other hand, self-ligating brackets include moving parts that become distorted, deformed or detached, thereby compromising the course of treatment.
To date, several self-locking or self-ligating brackets have been designed. However, most brackets have complex configurations and either incorporate features that require complex and expensive machining operations or include a plurality of separate parts that in turn increase the number of failures in such brackets. The complexity of the design and manufacturing processes for self-ligating orthodontic brackets 5 has pushed prices far above a conventional bracket and without providing the option of converting the bracket when necessary or replacing the clip in the event of breakage or malfunction.
So, there is a need for a self-ligating orthodontic bracket to overcome the shortcomings and limitations of the self-ligating brackets currently available 10. SUMMARY OF THE INVENTION
The innovative self-ligating orthodontic bracket includes a bracket or housing having a pair of upper fins separated from the pair of lower fins 15 by a channel that receives the defined arc between the fins. It should be noted that all the features described below of the innovative self-ligating orthodontic bracket may have a base or lower surface of the bracket which is configured to have a composite radius for better adaptation to the tooth surface. A clip slides along a sliding path defined by the upper and lower lashing fins in a direction that extends from the lower lashing fins to the upper lashing fins and is transverse to the direction that the channel extends. The clip covers an opening of the channel in such a way that an orthodontic arch is retained within the channel.
Preferably, the clip is made from a material with shape memory and includes a pair of arms, each arm preferably having an extension at a free end of the arm in a direction that is generally parallel to the channel and transverse to the direction in which the clip slides.
In the first incorporation of the innovative self-ligating orthodontic bracket, the extensions of the free ends (flaps) extend towards each other and to a wedge-shaped locking ramp in the upper bracket of the bracket. The wedge-shaped locking ramp has a first surface or a front surface facing the lower lashing fins extending upward and away obliquely relative to an upper surface of the sliding channel. The front and rear surfaces of the wedge-shaped locking ramp are connected to each other by a transition region. Accordingly, when the clip slides along the sliding channel from an open position towards a closed or locked position, that is, starting from the lower lashing fins to the upper lashing fins, the front surface of the locking ramp in wedge shape deflects 40 the free ends (flaps) of the clip arms vertically up and away from, at an oblique angle relative to the sliding channel and over the wedge-shaped locking ramp. Once the free ends (flaps) of the clip arms have slid past the wedge-shaped locking ramp, the free ends of the clip arms return down over the slide channel where the free ends (flaps) of the clip arms they are locked behind the locking ramp in the shape of a wedge free of transverse, coplanar or parallel locking forces 5 being exerted by the clip. The rear surface of the wedge-shaped locking ramp prevents the free ends (flaps) of the clip arms from sliding towards the open position or towards the lower fins.
In a second incorporation of the innovative self-ligating orthodontic bracket 10, a wedge-shaped locking ramp is located on the lower lashing fin. Each clip arm includes a locking tab facing inward in an intermediate position between the arms and an opposite base at the end of the clip body. The wedge-shaped locking ramp is located in the center of the clip's slide path. The locking ramp in the shape of a wedge 15 has a first surface or a front surface facing the lower lashing fins extending upward and away in an oblique manner relative to a surface of the sliding path. A second surface or rear surface of the wedge-shaped locking ramp faces the upper lashing fins extending essentially in an orthogonal direction relative to the upper surface of the sliding track. The front and rear surfaces of the wedge-shaped locking ramp are connected to each other by a transition region. Concomitantly, when the clip slides along the slide path from an open position towards a closed or locked position, the front surface of the wedge-shaped locking ramp deflects the free end of each clip arm and the clip locking tabs that extend internally are deflected vertically up and away at an oblique angle relative to the sliding path passing over the wedge-shaped locking ramp. As soon as the free ends of each arm of the 30 clip approach or contact the upper lashing fins, the locking flaps that extend internally are locked behind the locking ramp in the shape of a wedge, coplanar or with a locking force being exerted by the clip. The rear surface of the wedge-shaped locking ramp prevents the locking flaps that extend inwardly from sliding towards an open position or towards the lower lashing fins.
It is within the scope of the present invention for the second embodiment to be modified where an internally extending locking tab is provided at the free end of each clip arm.
In a third incorporation of the innovative self-ligating orthodontic bracket 40, a wedge-shaped locking ramp is positioned on the left and right sides of the slipway. Each wedge-shaped locking ramp has a first surface or a front surface facing towards the lower lashing fins and extends upwards and away from the upper surface of the slipway. A second surface or rear surface of each wedge-shaped locking ramp faces towards the upper mooring fins and extends essentially in an orthogonal direction relative to the upper surface of the sliding track. The front and rear surfaces of each wedge-shaped locking ramp are connected to each other by a transition region. The wedge-shaped locking ramps are located on the side of the upper lashing fins.
It should be noted that the front surface of each wedge-shaped locking ramp 10 may be perpendicular or orthogonal to the slipway.
In another alternative, the front surface of each wedge-shaped locking ramp can be tilted in relation to the slipway. The modification of the incorporation having the front surfaces of the wedge-shaped locking ramp 15 is to connect the wedge-shaped locking ramps with a defined beveled wall along a part of the upper surface of the sliding track between the sliding ramps wedge-shaped, where the beveled wall facilitates upward deflection of the arms locking flaps. 20 Concomitantly, regardless of which configuration of the wedge-shaped locking ramps described above, is provided with this third incorporation, when the clip is slid along the slide track from a closed or locked position, the front surface of each wedge-shaped locking ramp, deflects a locking flap of the corresponding arm 25 of the clip vertically upwards and away at an oblique angle relative to the sliding track passing over the wedge-shaped locking ramp.
Once the locking tabs slide in front of the wedge-shaped locking ramp, the clip's locking tabs return down 30 over the slide track where the locking tabs of the clip arms are locked behind the locking ramp in wedge shape free of transverse, coplanar or parallel locking forces being exerted by the clip. The rear surface of each wedge-shaped locking ramp prevents the corresponding locking tab arm from sliding towards the open position or towards the lower lashing fins.
According to a fourth incorporation of the innovative self-ligating orthodontic bracket, the sliding track is tilted or angled downwards in relation to the bottom surface of the arch channel and in a direction taken from the lower lashing fins towards the upper fins of 40 mooring.
The protrusion is included in the lower lashing fins of the slipway and positioned on the left and right sides of the slipway.
Each lump has a ramp surface. The flaps of the 5 arms of the clip are configured to cover the channel that receives the arch and has a first contiguous surface against a front surface of the upper mooring fin and with the possibility of a second surface adjoining the posterior, perpendicular surface of the protuberance that it also defines part of the channel that receives the arc. Concomitantly, when the clip is slid along the 10-slide track from an open position towards a closed or locked position, the front surface of each protuberance deflects the corresponding arm flap vertically up and away, in a oblique angle relative to the sliding track, over the protuberance and over the channel that receives the arc. . 15 Once the clip arm flaps have slid over the protrusion, the clip arm flap portion rests on a part of the sliding track located on the upper side of the bracket's upper mooring flap and the remaining portion of the clip's flap. arm covers the opening of the channel that receives the arc. The rear surface of the protrusion is confined by the second surface of each clip arm flap where the arm flaps are locked behind the transverse, coplanar or parallel lock-free protrusion being exerted by the clip.
The rear surface of each protuberance prevents the corresponding arm flap from sliding towards the open position or towards the lower lashing fins 25.
In a fifth embodiment of the self-ligating orthodontic bracket, as described above in the third embodiment, a wedge-shaped locking ramp is positioned on the left side and on the right side of the sliding track. Each wedge-shaped locking ramp has a first surface or front surface facing the lower lashing fins extending upward and away from the upper surface of the slipway. A second surface or rear surface of each wedge-shaped locking ramp faces towards the upper lashing fins and extends essentially in the orthogonal direction relative to the upper surface of the sliding stroke. The front and rear surfaces of each wedge-shaped locking ramp are only connected between them by a transition region. The wedge-shaped locking ramps are located on the upper side of the bracket mooring fin. In addition, the front surface of each wedge-shaped locking ramp can be perpendicular or orthogonal to the sliding track 40. inclined in relation to the slipway, or have wedge-shaped locking ramps connected to each other by a beveled wall defined along the part of the upper surface of the slipway between the wedge-shaped locking ramps, while beveled wall facilitates the deflection of the clip arm flaps upwards.
However, in the fifth incorporation, protuberance guides are included on the sides of the upper and lower mooring fins of the channel that receives the arch and centrally located along the sliding track. The protrusions deflect the clip arms upward or vertically at an oblique angle relative to the slipway or channel. When the clip is slid along the sliding track from an open position towards a closed or locked position, the flaps of the clip's arms at first are deflected vertically by the lower guide protrusion, then crosses the receiving channel the arch and again are deflected vertically and upwards by the upper guide bulge. Once the clip arm tabs span the upper protrusion guide, the clip arm tabs return down over the slide track where the clip arm tabs are locked behind the free wedge-shaped locking ramps of transverse, coplanar or parallel locking forces being exerted by the clip.
The rear surface of each wedge-shaped locking ramp prevents the flaps of the corresponding arms from sliding towards the open position or towards the lower lashing fins. 20 In addition, the innovative self-ligating orthodontic bracket is configured to provide a low profile while minimizing lip-lingual prominence. As noted above, the bracket includes a mounting base to hold the tooth surface, a channel that receives the arc formed on the base transversely oriented in relation to the mooring fins and sized to receive an orthodontic arch, a connecting clip of sliding memory retained within stabilizing channels with closure to capture and retain the orthodontic arch within the channel that receives the arch. The locking action of the sliding clip arms with shape memory can be based on the properties of the alloy and the properties of thermal activation at the mouth temperature. 30 A convertible bracket feature allows orthodontics professionals the option to continue using the bracket as treatment progresses towards the final stages of treatment without the need to change brackets. The convertible feature also makes it easier for orthodontists to use instruments that are normally used in clinical practice 35 during routine or normal procedures for bracket conversion.
Together with the convertibility aspect, the clip of the innovative self-ligating bracket allows the clip to be replaced with a simple operation step without the need to remove or change the bracket.
In addition, the innovative convertible self-ligating orthodontic bracket 40 includes a sliding clip with shape memory. It has a significant improvement in fatigue resistance, supporting numerous opening and closing cycles, remaining active and operational in an aggressive environment such as the mouth during the entire orthodontic treatment. . Preferably, the shape memory clip is manufactured from a Ni / Ti superelastic alloy by stamping, photo corrosion, laser cutting, or any other process currently known or to be developed later bringing advantages such as, 5 increase resistance, flexibility, resilience, durability, reliability, shape memory and others.
Additional aspects and new features related to the present invention will be set out below in part in the following description and in part it will be clearer to those of skill in the art about the following exams or about learning by practicing aspects of the invention.

DETAILED DESCRIPTION OF PREFERENTIAL INCORPORATIONS
In the following detailed descriptions, a number of specific details 20 are established in order to provide a complete understanding of the present invention. However, those skilled in the art will understand that the present invention can be practiced without these specific details, that the present invention can be practiced in a variety of alternative embodiments. In other instances, well-known methods, procedures, components and systems have not been described in detail.
Various operations will be described as multiple steps performed in a manner that is useful for understanding the present invention. However, the order of description should not be constructed to imply that these operations are necessarily performed in the order in which they are presented and not even dependent on the order.
Figure 1 illustrates a front view of the self-ligating orthodontic bracket 10 according to the first embodiment of the present invention. The bracket 10 includes a bracket or a housing 4 and configured to receive an AO orthodontic arch (Figure 5), and a sliding binding member or clip 3, shown in 35 in a closed or locked position, which retains the AO orthodontic arch within the channel 2 that receives the arc. The bracket 10 subsequently includes a pair of upper mooring fins 5 separated from the opposite pair of the lower mooring fins 6 by the channel that receives the arch 2 defined between the fins.
It should be noted that the bracket 10 described here, as well as any other incorporation of the innovative brackets, can have a base or a lower surface configured to have a compound radius which should better adapt the surface of the corresponding tooth.
Furthermore, in the first incorporation as well as in any other incorporation discussed later, at least one of the upper mooring fins 5 and the lower mooring fins 6 can form integrally with the housing 4 or as a separate component that is fixed on the 5 fins .
The components of bracket 10 can be formed from any currently known technique or other manufacturing process developed later, such as metal injection, stamping, photo-corrosion, laser cutting, machining, casting, sintering, microfusion and the like. 10 Hereinafter, it is included in the scope of the invention so when such components are separate and distinct from each other they can be joined using any manufacturing technique currently known such as, use of adhesives, ultrasonic welding or other manufacturing technique subsequently developed. Biocompatible metal alloys, composite material and ceramics are materials of which at least one or preferably all components of the innovative bracket can be manufactured.
Clip 3 is configured to move within a sliding track PD defined by upper and lower lashing fins 5 and 6, respectively, in a direction that extends from the lower lashing fins 6 20 to the upper lashing fins 5 as which are transverse in relation to the direction in which channel 2 that receives the arc extends. Clip 3 is preferably manufactured from a shape memory material and includes a pair of arms 7, each arm may have a tab 7a extending from a free end of arm 7 in a direction that is generally parallel to the channel 2 25 that receives the arc and transverse the direction in which the clip 3 slides.
In an unlocked state (Figures 2-4), clip 3 does not cover channel 2 that receives the arc when the flaps 7a of each arm 7 are located on the side of the lower mooring fin on the underside of channel 2 that receives the bow. Clip 3 slides along a PD sliding track from an unlocked state or position to a locking state or position (Figures 1 and 5-6) where the flaps 7a of each arm 7 are positioned within the sliding track. PD slide along which the clip 3 moves when going from the unlocked state or position to the locked state or position.
Similarly, in the first incorporation as well as in the other 35 incorporations discussed later, the wedge-shaped locking ramp 1 can be integrally formed together with the housing 4 or as a separate component that is fixed in that place. The wedge-shaped locking ramp 1 can be formed from any technique currently known or further developed such as those mentioned above. Further, 40 is included in the scope of the invention for when the wedge-shaped locking ramp 1 is a separate and distinct component relative to the other components of the housing, the wedge-shaped locking ramp 1 can be joined to the housing 4 using any manufacturing technique currently known or later developed such as adhesive, ultrasonic welding, interference locking and the like. For example, it is anticipated that the housing 4 may have clips defined in that place that can be fitted and securely held there or any other type of projections that are configured to be engaged through the holes in the clips and held in that place.
In the first embodiment of the invention, the wedge-shaped locking ramp 1 is positioned substantially within the center of the slipway PD and at least on a longitudinal axis L of the slipway 10 PD extending from the lower lashing fins 6 to the upper lashing fins 5.
As shown in more detail in Figures 3-5, the wedge-shaped locking ramp 1 has a first surface or a front surface 1a facing towards the lower lashing fins 6 and extending essentially orthogonal to the upper surface of the PD slipway. The front surface 1a and the rear surface 1b of the wedge-shaped locking ramp 1 are connected to each other by a transition surface 1c, which preferably, but not limited to an arcuate shape.
Suitably, a professional in the field of orthodontics would position and 20 attach the AO orthodontic arch within channel 2 of bracket 10 as follows.
First, as shown in Figure 2, in an unlocked state, clip 3 is slid along the slide path PD starting at the lower lashing fins 6 towards the upper lashing fins 5. That is, the flaps 25 7a of each arm 7 of clip 3 is positioned on the side of the lower fin on the underside of channel 2 so that channel 2 is exposed to the orthodontic professional. As shown in Figure 3, which is a cross-sectional view of the side view illustrated in Figure 2, and Figure 4, which is a perspective view of the front view illustrated in Figure 2, the flaps 7a do not completely cover or case 30 otherwise they would completely block the channel 2 that receives the AO orthodontic arch, thus providing orthodontics professionals with sufficient access to channel 2 to position the AO orthodontic arch within the channel 2.
Once the AO orthodontic arch is positioned inside channel 2, clip 3 is slid forward along the sliding track PD to completely cover channel 2 starting from an open or unlocked state to a closed or locking state, that is, from the lower locking fins 6 towards the upper locking fins 5, where the front surface 1a of the wedge-shaped locking ramp 1 deflects each flap 7a of each arm 7 of the clip 3 vertically or at least obliquely upwards and away from, at an oblique angle relative to the upper surface of the PD sliding track and over the wedge-shaped locking ramp 1. Once the flaps 7 a of each arm 7 slide over the locking ramp in wedge-shaped 1, the flaps 7 a return downward over the sliding track PD where the flaps 7 a are positioned between the wedge-shaped locking ramp 1 and the upper lashing fins 6, as shown in the sectional view of Figure 5 and in the perspective view of the same figure which is shown in Figure 6. Flaps 7 to 5 are locked or secured by the wedge-shaped locking ramp 1 free from any transverse, coplanar or parallel locking force being exerted by the clip 3. Therefore, the rear surface 1b of the wedge-shaped locking ramp 1 prevents the flaps 7 from sliding it towards the lower lashing fins 6 to an open or unlocked position. In addition, as shown in Figure 5, the 10 flaps 7 a of each arm 7 are sized and configured to engage the rear surface 1b of the wedge-shaped locking ramp 1. Although Figure 5 illustrates the flaps 7a are free to contact the upper mooring fins 5 when in a locking state as evidenced by the opening or space defined between the flaps 7a and the upper mooring fins 5, it is within the scope of the invention for the flaps 7a to be dimensioned and configured to physically contact or engage the rear surface 1b of the wedge-shaped locking ramp 1 and the surface of the upper lashing fins 5 which is opposite the rear surface 1b such as that on which the flaps 7a are securely or firmly held between them. Figure 7 illustrates a front view of the self-ligating orthodontic bracket according to a second embodiment of the present invention. The bracket 110 includes a self-ligating orthodontic bracket or housing 14 for fixing to the tooth surface, a channel 12 defined by the housing 14 and configured to receive the AO orthodontic arch, and a sliding binder member or clip 13 illustrated in the closed or locked position which retains the AO orthodontic arch within channel 12. Bracket 110 further includes a pair of upper mooring fins 15 separated from an opposite pair of lower mooring fins 16 by a channel 12 defined between the pairs of fins. Clip 13 is configured to slide within a PD 30 slide track defined by the upper and lower lashing fins 15 and 16 respectively, in a direction that extends from the lower lashing fins 16 to the upper lashing fins 15 which is transverse relative to the direction in which the channel 12 extends. The clip 13 includes a pair of arms 17, and like the arms 7 of the first embodiment, each arm 17 of the second embodiment 35 may optionally have a flap 17a extending from a free end of the arm 17 in a direction that is generally parallel to the channel 12 and crosses the direction in which the clip 13 slides. In addition, each arm 17 also includes a locking tab 18 extended inwardly located intermediate the base of the clip 16 towards the upper lashing fins 15. Suitably, while 40 the flaps 17a are optional structural components of the arms 17 in the second incorporating the invention, the locking tabs 18 directed inwardly are affirmatively provided for.
In this way, the locking tabs 18 of each arm 17 extend towards the locking tab 18 of the other arm 17. The locking tabs 18 can be configured to resemble any geometric shape currently known or further developed as long as the 5 locking tabs 18 are able to engage and be retained by a wedge-shaped locking ramp 11 discussed below.
Also, while the inwardly facing locking tabs 18 are preferably manufactured to be an integral part of the rest of the clipel3, it is within the scope of the invention for the tabs 18 to be formed as a separate and distinct component from the rest of the clip 13, in that the locking tabs 18 are attached or attached to the corresponding arm 17 using any technique currently known or that will be developed later, such as an adhesive, ultrasonic welding, interference locking, and the like.
In the locking state, as is clearly shown in 15 Figures 7 and 11-12, the locking tabs 18 that extend into the clip on each arm 17 are located between the upper lashing fins 15 and the shaped locking ramp wedge 11 positioned within the sliding track PD along which the clip 13 moves when going from an unlocked state or position to a locked state or position. In a second embodiment of the invention, the wedge-shaped locking ramp 11 is positioned substantially in the center of the slipway PD and at least on the longitudinal axis L of the slipway PD extending from the lower lashing fins 16 to the upper mooring fins 15. In addition, the wedge-shaped locking ramp 11 is located on the side of the lower mooring fin on the underside of the channel 12 that receives the arch. As best shown in Figures 9 and 11, the wedge-shaped locking ramp 11 has a first surface or a front surface 11a facing towards the lower lashing fins 16 and extending 30 up and away in a relative oblique manner to an upper surface of the PD sliding track. A second surface or rear surface 11b of the wedge-shaped locking ramp 11 faces towards the upper lashing fins 15 extending essentially orthogonal to the upper surface of the sliding track PD. It is within the scope of the invention 35 for the rear surface 11b of the wedge-shaped locking ramp 11 to form a continuous surface of a first wall 12a extending over the channel 12, as shown clearly in Figure 9.
However, it is also within the scope of the invention for the wedge-shaped locking ramp 11 to be positioned between the channel 12 and the 40 lower lashing fins 15 such that the rear surface 11b of the wedge-shaped locking ramp 11 is separate and distinct from a first wall 12a extending upwardly from the channel 12 in a way that an upper surface of the slide track PD along which the clip 13 slides is positioned between the rear surface 11b of the shaped locking ramp wedge 11 and channel 12.
Preferably, the front surface 11a and the rear surface 11b 5 of the wedge-shaped locking ramp 11 are connected to each other by a transition surface 11c, which can be arched or any other suitable geometric configuration.
Suitably, an orthodontic professional could position and retain the orthodontic arch within channel 12 of bracket 110 as follows. 10 First, as shown in Figure 8, in an unlocked state, clip 13 is slid along the slide track PD starting from the lower lashing fins 16 towards the upper lashing fins 15. That is, the locking tabs18 that extend towards each arm 17 of the clip 13 are located on the side of the lower lashing fin on the underside 15 of the channel 12 so that the channel 12 is exposed to the orthodontic professional. As shown in Figure 9, which is a cross-sectional view of the side plane shown in Figure 8 and Figure 10, which is a perspective view of the front plane of Figure 8, the free ends of the arms 17 do not completely cover the channel 12 or otherwise they would totally block the 20 channel 12, thus providing orthodontics professionals access to channel 12 to position the AO orthodontic arch within channel 12.
Once the orthodontic arch AO is positioned inside the channel 12, the clip 13 is slid further and along the sliding track PD where the arms 17 fully cover the channel 12, from an unlocked state 25 to a state closed or locking, that is, from the lower lashing fins 16 towards the upper lashing fins 15, where the front surface 11a of the wedge-shaped locking ramp 11 deflects each locking tab 18 facing into each arm 17 of clip 13 vertically or at least obliquely up and away from, at an oblique angle relative to the top surface 30 of the PD sliding track and over the wedge-shaped locking ramp 11. Since the locking tabs 18 of each arm 17, are slid past the wedge-shaped locking ramp 11, the locking tabs return down over the slide track PD where the locking tabs 18 are positioned between the locking ramp 35 wedge-shaped lock 11 and the upper lashing fins 15 as shown in the cross-sectional view of Figure 11 and a perspective view shown in Figure 12. The locking tabs 18 that extend inward are locked or secured by the ramp wedge-shaped locking mechanism 11 free of any transverse, coplanar or parallel force being exerted by clip 13, thus securely retaining the orthodontic arc 40 within the channel 12. That is, the rear surface 11b of the locking ramp wedge 11 prevents the locking tabs 18 from sliding towards the lower lashing fins 16 to an open or unlocked position. 5 10 15 20 25 30 35 40
In addition, as shown in Figures 7 and 11-12, the locking tabs 18 of each arm 17 are dimensioned and configured to engage the rear surface 11b of the wedge-shaped locking ramp 11.
Figure 13 illustrates a perspective view of the self-ligating orthodontic bracket 210 according to a third embodiment of the present invention.
The bracket 210 includes a base of the bracket that is fixed to the tooth surface, a channel 102 configured to receive the orthodontic arch AO, and a sliding binding member or clip 103 which retains the orthodontic arch AO within the channel 102. Clip 103, like clips 3 and 13 of the first and second embodiments, can be selectively manipulated from a closed or locked state in Figure 13 to an open or closed state, thereby exposing channel 102 that extends transversely relative to the track PD slide where clip 103 slides to allow the orthodontic professional to insert the AO orthodontic arch into channel 102. Bracket 210 further includes a pair of upper lashing fins 105, separated by a pair of opposite lower lashing fins 106 by a channel 102 defined between the upper and lower fins.
Clip 103 is configured to move along the sliding track PD defined by the upper and lower fins 105 and 106 respectively, in a direction that extends from the lower lashing fin 106 to the upper lashing fin 105 and which is transverse in relation to the direction that the channel 102 extends. Clip 103 is preferably made of a shape memory material and includes a pair of arms 107 in a direction that is generally parallel to channel 102 and transverse to the direction in which clip 103 slides.
However, unlike the first embodiment where the flaps 7a extend in a converging direction, the flaps 107a of the third embodiment extend in the opposite direction to each other just as the flaps 107a extend away from the longitudinal axis of the sliding track. SP which extends from the lower mooring fin 106 towards the upper mooring fin 105.
In addition, clip 103 slides along the sliding track SP 103 and within the sliding channel CD defined by mesial and distal walls of the lower lashing fins 105 and transversely oriented in relation to channel 102 or parallel to the longitudinal axis of the sliding track PD.
In an unlocked state, clip 103 does not cover channel 102 when the flaps 107a of each arm 107 are positioned on the lower lashing fins on the underside of channel 102. Clip 103 moves along the PD sliding track from an unlocked state or position to a locking state or position where the flaps 107a of each arm 107 are positioned on the upper lashing fins on the upper side of the channel 102. As shown clearly in Figure 13, the flaps 107a of each arm 107 are located between the upper lashing fins 105 and a locking ramp
101 positioned on the left and right sides of the PD sliding track along which the clip 103 moves when going from an unlocked state or position to a locked state or position.
In a third embodiment of the invention, a wedge-shaped locking ramp 101 is positioned on the left and right sides of the PD sliding track on the side of the upper lashing fin of the bracket 210. Each wedge-shaped locking ramp 101 has a first front surface 101a facing the lower lashing fins 106 and extending upwards and away from an upper surface of the 10-slide track PD. A second or rear surface 101b of the wedge-shaped locking ramp 101 faces the upper lashing fins 106 and extends essentially orthogonal to the upper surface of the sliding track PD. The front surface 101a and the rear surface 101b of the wedge-shaped locking ramp 101 are connected to each other by a transition surface 101c.
It is within the scope of the invention for the front surface 101a of each wedge-shaped locking ramp 101 of the third embodiment that is perpendicular to the sliding track PD, as illustrated in Figures 13 and 14. 20 Alternatively, as shown in 15, the front surface 101a of the wedge-shaped locking ramp 101 can be inclined relative to the sliding track PD with a beveled surface. A modification of the embodiment shown in Figure 15 is to connect the wedge-shaped locking ramps101, 101, with a beveled wall 170 defined along the portion 25 of the upper surface of the PD slide track between the wedge-shaped locking ramps 101,101, where the beveled wall 170 facilitates deflection over the flaps 107a of the arms. The modification of the embodiment shown in Figure 15 is included in Figures 16-18.
As emphasized above, each version of the third embodiment includes a wedge-shaped locking ramp 101,101 on the left and right sides of the PD sliding track.
In addition, in addition to the constitution of the PD sliding track, each bracket 1.110 and 210, and even those that will be described hereinafter, can optionally include a coplanar locking recess 35 defined by the lower locking fins6,16 and 106 below , for example, which is used to lock the flaps 7a, 17a, and 107a of clip 3, 13 and 103 in an open or unlocked state. A circular opening 130, defined by an open area between the arms 7, 7, 17, 17 and 107,107 of clip 3, 13 and 103, and with the first wall extending upwards 12a from channel 2, 12 and 102. One orthodontic instrument 40 such as, for example, a probe can be inserted into the circular opening 130 and with a rotating lever movement of approximately 45 ° in relation to the sliding track PD, the clip 3, 13 and 103 will be released from the wedge-shaped locking 1, 11 and 101 as described above to the others that will be discussed later, thereby exposing channel 2, 12, 102 to the orthodontic professional.
Returning to the embodiment shown in Figure 14, which for the following 5 discussions is an exemplary embodiment of the bracket illustrated in Figures 13-18, the AO orthodontic arch is clearly shown to be captured or securely retained in channel 102 by clip 103 in a closed state or locked. Clip 103 includes flaps 107a securing and securely retained by the rear surface 101b of the wedge-shaped locking ramps 10 101, 101. The flaps 107a and 107a are positioned between the rear surface 101b of the wedge-shaped locking ramps 101, 101 and the upper lashing fins 105, 105.
In addition, the lower lashing fins 106, 106 include protrusions 150, 150 extending inwardly from the left and right sides towards the longitudinal axis L of the sliding track PD. When the orthodontic professional is manipulating clip 3, 13 and 103 downwards or from a closed state to an open or unlocked state in the manner described above, the flaps 107a, 107a of the arms 107, 107 contact the protrusions 150, 150 , respectively, are elastically deflected towards each other or to 20 in towards the longitudinal axis L of the sliding track PD. Since the flaps 107a, 107a move over or over the protrusions 150, 150, the arms 107, 107 deflect elastically away from each other or away from the longitudinal axis L of the sliding track PD returning to its original shape, shape by locking clip 3, 13, 103 in the coplanar locking recess 25 140.
Suitably, regardless of which incorporation of bracket 110 illustrated in Figures 13-18 is being used, the orthodontic professional would position and retain the AO orthodontic arch within channel 102 of bracket 110 as follows. The clip 103 is manipulated along the sliding track PD from an open or unlocked state to toward a closed or locked state. The front surface 101a of the wedge-shaped locking ramp 101 deflects the corresponding flap 107a vertically up and away, at an oblique angle, in relation to the upper surface of the slide track 35 PD, and over the locking ramp in wedge shape 101.
Since the flaps 107a, 107a have passed over and beyond their corresponding wedge-shaped locking ramp 101, 101, each flap 107a returns down over the sliding track PD and rests within a defined recess between the rear surface 101b of each ramp 101 and the 40 corresponding upper lashing fin 105, where each flap 107a is retained or securely locked behind the wedge-shaped locking ramp 101 free from any transverse, coplanar or parallel locking force exerted by clip 103. That is, the rear surface 101b of each wedge-shaped locking ramp 101 locks and prevents the corresponding flap 107a from sliding towards an open state or the lower lashing fins 106.
Figures 19 and 20 illustrate a fourth embodiment of the bracket 310 5 of the present invention, where clip 203 slides along an inclined PD slide track within an inclined CD slide channel defined by the distal and mesial walls of the lower lashing fins. 206 and oriented transversely with respect to channel 202. In addition, a wedge-shaped locking ramp 201 is incorporated into the left and right sides of the PD sliding track. It is within the scope of the present invention for wedge-shaped locking ramps 201 to be located preferably adjacent to or near channel 202. Each locking ramp 201 has an inclined or ramped front surface 201a. Clip 203 includes a pair of arms 207, each arm 207 has a flap 207a located at the free end 15 so that it extends away from flap 207a of the other arm 207. As shown in Figures 19 and 20, each flap 207a is configured to cover the entire channel 202 so that when clip 203 is in a closed or locked state, a first edge 208 locks on the rear surface 201b of the corresponding wedge-shaped locking ramp 201 and the orthodontic arch 20 AO is retained on channel 202.
Optionally, each flap 207a can also be configured to have a second edge 209 which locks on the corresponding upper lashing fin 205.
Suitably, when clip 203 is slid into an inclined CD sliding channel and along an inclined PD sliding track from an open position towards a closed position, the sloped or ramped front surface 201a of the locking ramp in wedge shape 201 deflects the first edge 208 of the corresponding flap 207a vertically up and away, at an oblique angle to the sliding track PD over the wedge-shaped locking ramp 201 and through the channel 202. A Since the flaps 207a and 207a are slid past the corresponding wedge-shaped locking ramp 201, a portion of each flap 207a rests on a part of the sliding track PD located on the top side of the upper lashing fin 210, and portion remainder of each flap 207a covers the opening of channel 202. 35 The rear surface 201b of the wedge-shaped locking ramp 201 is surrounded by the first edge 208 of each flap 207a where the flaps the 207a, 207a are locked behind the corresponding wedge-shaped locking ramp 201, free of transverse, coplanar, or parallel locking forces being exerted by clip 203 preventing the corresponding flap 207a from sliding in 40 direction to the open position or in towards the lower lashing fins 206.
Figures 21-23 illustrate a fifth embodiment of the self-ligating orthodontic bracket 410 where, as described above in the third embodiment, a wedge-shaped locking ramp 301 has a first surface or front surface 301a towards the lower mooring fins 5 306, 306 and extending upwards and away from the upper surface of the PD sliding track. A second surface or rear surface 301b of each wedge-shaped locking ramp facing towards the upper lashing fins 305 and extending essentially diagonally with respect to the upper surface of the sliding track PD. The front and rear surfaces 10 301a and 301b of each wedge-shaped locking ramp 301, 301 are located on the side of the upper lashing fin above the channel 302 defined in bracket 410. Furthermore, the front surface 301a of each ramp wedge-shaped locking device 301 can be perpendicular or orthogonal to the sliding track PD; inclined in relation to the sliding track PD; or have 15 wedge-shaped locking ramps 301, 301 connected to each other by a beveled wall 170 (Figure 16) defined along a portion of the upper surface of the PD slide path between the wedge-shaped locking ramps 301, 301, where the beveled wall 170 facilitates upward deflection of the flaps 307a, 307a, extending from the corresponding arms 307, 307 of the clip 20 303.
Furthermore, in the fifth embodiment, an upper guide protrusion 325 and a lower guide protrusion 326 are included, respectively, in the upper and lower mooring fins to the channel 302 and centrally located along the sliding track PD. The protrusions 325 and 326 deflect the 25 arms 307, 307 of the clip 303 upwards and vertically at an oblique angle to the sliding track PD or sliding channel CD. When the clip 303 is slid along the slide path PD from an open position towards a closed or locked position, the flaps 307a, 307a are first deflected vertically by the lower guide protrusion 326, then 30 across the channel 302, and are again deflected vertically by the upper guide protrusions 325. Since the flaps 307a, 307a are deflected over the upper guide protrusions 325, the flaps 307a, 307a return down over the slide path PD where the flaps 307a, 307a are locked behind the wedge-shaped locking ramps 301, 301 free of forces of transverse, coplanar or parallel locking being exerted by the clip 303. The rear surface 301b of each wedge-shaped locking ramp 301 prevents the corresponding flap 307a slide towards the open position or towards the lower 306 lashing fins.
Figure 24 is a perspective view of an exemplary embodiment 40 of a sliding clip 1300 made from a material having shape memory.
Preferably, clip 1300 is manufactured from an alloy with shape memory (LMF), which is a metal alloy capable of returning to a previously defined shape and / or size when subjected to an appropriate thermal procedure. In general, LMF deform plastically at a relatively low temperature and when exposed to a higher temperature, LMFs return to their previous shape, that is, the shape before being exposed to a relatively low temperature. Shape Memory Alloys exhibit shape memory only when heated and are referred to as one-way shape memory, while materials which undergo a change in shape during cooling are referred to as two-way shape memory. Forma Memory Alloys have two stable phases, a first phase occurs during the high temperature phase and is referred to as austenitic, while the second phase occurs during the low temperature phase and is referred to as martensitic. Furthermore, martensite can be presented in one of two forms, interlaced and 15 deinterlaced. A phase transformation which occurs between the austenitic and martensitic phases during heating / cooling is known as the basis for a unique feature provided by the Shape Memory Alloys.
For example, if clip 1300 is made from a Shape Memory League and cooled, in the absence of an applied load, the Shape Memory League 20 changes from the austenitic to the martensitic phase. Suitably, the Shape Memory League can be transformed from the austenitic phase where clip 1300 has a geometric configuration previously determined for the martensitic phase where clip 1300 transforms, such as, for example, shrinks, into another configuration. As applied to the present invention, it is within the scope of the invention where clip 1300 is cooled or transformed from austenitic to martensitic so that clip 1300 transforms or shrinks in size and / or configuration. The orthodontic professional then takes the clip in the martensitic phase or in a shrunken state and inserts the 1300 clip into any of the aforementioned brackets. Once the clip 1300 is inserted into the bracket that is previously affixed to the patient's tooth surface, the temperature inside the patient's mouth will heat the clip 1300, thereby providing clip 1300 with a reverse transformation from the martensitic phase to the austenitic phase. That is, clip 1300 expands or transforms to a predetermined configuration or geometric shape. Suitably, and only as an example, the legs and / or tabs and / or locking tabs that extend internally in any of the aforementioned clips would expand or increase their dimensional size, thereby being more securely retained or locked with the various components structural elements of the aforementioned brackets, 40 such as, in the not limited to, walls of the lower lashing fins which define the CD sliding channel, the rear surface of any of the wedge-shaped locking ramps, and / or the upper mooring.
The material and the heat treatment process used to manufacture the 1300 shape memory clip brings versatility in the design and in the multiple 5 choices in flexibility, geometric configurations, thickness, shape memory recovery and martensitic to austenitic transformation from room temperature for the temperature of the mouth. The 1300 shape memory sliding clip can be formed from any material that has the flexibility to allow repetitive movements or deflections in the assembly, 10 opening and closing operations. More specifically, the material that forms the memory alloy sliding clip 1300 must undergo elastic deformation without significant plastic deformation occurring when deflected or bent during the course of orthodontic treatment.
Although numerous alloys that exhibit shape memory effect are known, alloys that recover a substantial amount of shape and that generate significant strength when changing shape are considered viable for use with the 1300 clip of the innovative bracket described above.
Examples of such alloys include, but are not limited to, Nickel-Titanium alloys (eg, NiTi) and Copper based alloys (eg, CuZnAI, CuAINi). It is known that 20 nickel-titanium alloys have a greater memory recovery compared to copper based alloys, as well as being more thermally stable, have excellent resistance to corrosion and greater resilience. However, it is also known that copper-based alloys cost less than nickel-titanium alloys, are capable of being easily melted and extruded into the air, and have a greater potential range of transformation temperatures. The 1300 clip can therefore be manufactured from two alloys described above while taking into account the advantages and disadvantages highlighted above considering the particularity of the application.
Many modifications can be made to adapt the teachings 30 of the bracket of this invention to specific or material situations without departing from the scope presented here. Therefore, this invention should not be limited to the incorporations disclosed herein, but include all incorporations within the spirit and scope of this disclosure.
For example, the orthodontic bracket illustrated in the attached figures 35 may include such additional features as a low profile due to the geometric design where it is not necessary to have a higher profile in the lip / lingual dimension to accommodate the bracket opening and closing mechanism and sliding clip. .
Together, the bracket may include rounded corners, a beveled groove and a convex shape oriented from gingival to occlusal or gingival to incisal to help prevent lip interference, thereby improving patient comfort and adaptation to the device. 5 Subsequently, the upper and lower mooring fins can be configured to provide a sufficiently wide space under the fins to facilitate the placement of auxiliary and connection accessories different from other self-ligating brackets where this important feature is missing.
