    REMOVABLE DENTURE SYSTEM
    FIELD OF THE SUBJECT REVEALED
    The subject disclosed here concerns, in general, the field of dentures. More particularly, the disclosure relates to a system and method for the stabilized assembly of a denture, yet, in a readily removable manner.
    HISTORY OF THE SUBJECT REVEALED
    The partial or complete loss of an individual's natural teeth, whether of the jaw or the jaw, due to age, accident, illness or other reasons have some serious effects on an individual, both functional and socially. The lack of teeth imposes several serious functional problems, such as not being able to chew, speech difficulties, etc. Furthermore, a smile with a complete set of white teeth is considered something to be desired, that is, aesthetics play an important role in life.
    Although a denture can be precisely fitted to an individual's alveolar ridge, it is difficult to hold a denture in position. That is, during chewing or normal speech, the denture has a tendency to jump out of position on the alveolar ridge, causing speech difficulties, chewing difficulties and unsatisfactory general use of a denture.
    A denture is a removable dental prosthesis that has artificial teeth embedded in a denture-like base. The base of the denture provides support for the prosthesis by resting on the gum or on a support bar fixed to the respective jaw bone by a plurality of dental implants. The interior of the base of the denture has a depression receptacle that receives at least part of the gum or support bar, in order to
    2/29 provide a pleasant, reversible denture fit.
    In recent years, the practice has developed the permanent implantation of dental implants (sometimes referred to as dental fixations or pins) in the bone structure of the mouth. These permanent dental implants are made of rigid material acceptable for the biological processes of the body (for example, titanium) and which are locked in position by bone growth. By using the implants permanently installed in the individual's mouth, then, there is the possibility of more quickly attaching a denture in the fixed or removable place.
    document W006103648 discloses a removable denture system comprising a support rod fixedly attached to the individual's alveolar ridge above the mucous membrane by a plurality of dental implants, and a denture that generally conforms to the individual's dental parameters and is integrated to a superstructure. The superstructure comprises at least a part formed in conformity with the support rod, and a denture locking arrangement for removably articulating, albeit fixedly, the denture for the rod
    support, avoiding unintentional undocking gives denture. 0 document US 5.0132.43 reveals a fixation in denture including a magnet body, to be incorporated into an
    denture base, comprises a pair of soft magnetic alloy end plates, a non-magnetic alloy spacer disposed between the end plates, and a cover covering the magnet body, the end plates and the spacer, except on the side of a ridge. The fixation causes an attractive magnetic force of the magnet body to act on the top of a magnetic alloy mold incorporated in a pulp cavity of a tooth without a crown, thus the base of the denture is
    3/29 stabilized in the gum. The magnet body is arranged with its N and S poles facing the end plates, respectively.
    SUMMARY OF THE SUBJECT REVEALED

    According to a first design of the locking mechanism, at least one first magnet is provided fixed within the support rod and oriented with a pole facing upwards; a disk-type manipulator received within the denture and rotatable on an axis substantially parallel to an axis of said first magnet; said manipulator projecting partially from at least one lingual or labial face of the denture and holding at least a second oriented magnet with an opposite pole facing the support rod; said disk-type manipulator being movable
    9/29 between a locked position, in which said at least one second magnet extends substantially coaxially with said said at least one first magnet, giving rise to the force of attraction between them and in which the denture is attracted to the support rod , and an unlocked position, when rotating the disk-type manipulator, with this the attraction force decreases significantly, in order to allow the denture removal.
    One of the first magnet and the second magnet can be a piece of ferrous metal configured to attract the magnetic member provided in the support rod or denture.
    According to an example, a second additional magnet (a rejection magnet) is provided, however, with its poles reversed in relation to said second magnet (that is, oriented like the first magnet), thus, the positioning of the manipulator disc type with the second additional magnet extending over the first magnet results in a rejection force between them, facilitating the extraction / removal of the denture;
    According to a particular design, the disk-type manipulator passes through the superstructure.
    According to a particular design, the locking mechanism is configured at the rear end of the denture.
    When the first two magnets are provided, it extends along an arc line of the denture, in which the disk-type manipulator is displaced 90 ° between their respective positions. When only a first magnet is provided, the disk-type manipulator is moved between 90 ° 270 ° in the unlocked position.
    According to a different configuration, the locking mechanism comprises one or two locking recesses configured in the support rod and the denture is configured with a disk-type manipulator received inside

    According to a particular design, the locking members extend tangentially from the disk-type manipulator.
    The locking recesses are configured inside or on an upper surface of the support rod.
    The design is such that the locking mechanism, according to any of the configurations disclosed here, does not in itself support loads, that is, when the denture is mounted on the support rod, during chewing, the forces react substantially between the superstructure and the support rod, and substantially no force is supported by the locking system.
    In addition, a locking mechanism can be configured with an arrangement designed to assist in unlocking it from a lip direction.

    DETAILED DESCRIPTION OF ACHIEVEMENTS
    First, attention is directed to Figures 1 to 4 of the drawings which illustrate a denture system generally designated as 10, in accordance with the present disclosed subject. The denture system 10 comprises a support rod 20 fixedly attached to a jaw bone 24 (i.e., to the individual's alveolar ridge above the mucous membrane) of an individual, by a plurality of dental implants 26 received within the bone jaw 24 and, where the support rod 20 is attached to said dental implants 26 by suitable screws 28.
    The support rod 20 follows the general arcuate shape of the mandible 24 and is configured with a lingual (internal) face 30, a labial (external) face 32 and an upper surface 36.
    It is apparent from the drawings that the upper surface 36 of the support rod 20 is substantially flat and soft
    15/29 along its entire length. However, it is appreciated that the upper surface may not be flat over its entire length.
    The denture 42 is configured to be removably mounted on the support rod 20, as will be discussed below, and is customized in order to conform to the individual's dental parameters, namely, that comprise a plurality of teeth 44, similar to the teeth natural features of the individual as well as the shape, size and color and a gingival portion 46 configured to extend below the support rod when mounted on it and to cover at least a part of the mucous membrane (the part of the individual's natural gingiva) . Fixedly integrated within a lower surface of the custom denture 42, there is a superstructure 50 having a cross section that conforms to that of the support rod 20 and adapted for comfortable mounting on it substantially in zero tolerance, for the purpose of which it is provided with an upper wall 54 which is substantially flat and soft configured for level positioning on the upper surface 36 of the support rod 20 and corresponding lingual surface 56 and lip surface 58 for smooth and level engagement with the corresponding lingual surface 30 and lip surface 32 of support 20. However, it is appreciated that the lower surface of the superstructure can be configured to fit along its entire length with the upper surface of the support rod, or at least along its substantial parts.
    It is appreciated that the custom denture 42 is configured for application and removal of the support rod 20 along an insertion path (POI), namely, the imaginary line along which the custom denture 42 is placed or removed from the rod support 20, crossing the plane
    16/29 occlusal of the individual's mouth.
    As can be seen further, in particular in Figures 1A and IB, the support rod 20 is configured with a plurality of positioning projections that project laterally 60 (four, in the present case, two in each one between the lingual surface 30 and the labial surface 32) said positioning projections 60 extending parallel to the insertion path and parallel to each other, while the superstructure 50 is configured with a corresponding number of positioning grooves 64 that extend in the register with the positioning projections 60 separately. configured for comfortable sliding over them in substantially zero tolerance.
    It can be seen, in the particular example, that the positioning projections 60 extend over the entire height of the support rod 20 and are configured with a rounded shape, in order to minimize irrigation by removing the custom denture 42. On the other hand , the positioning grooves 64 extend from the lower surface 68 of the superstructure to the upper surface 54 and, as mentioned above, are configured for comfortable sliding over the positioning projections 60.
    The denture system 10 is further configured with a locking mechanism 76 which, in the present example, is a pin type locking arrangement disclosed in further details in Figures 19A and 19B.
    Now, additional attention is directed to Figures 5 and 6 of the drawings, where the general aspects of the support rod generally designated as 90 and the custom denture generally designated as 92 with the integrated superstructure generally designated as 94 substantially follow the aspects, as discussed above, in connection with Figures 1 to 4.
    17/29
    However, in the example illustrated in particular in Figures 5A and 5B, the positioning projections 100 are trapezoidal with a wide bottom base 102 that narrows upwards towards a narrow top base 104 where, in the particular example, the bottom base 102 extends downwardly towards a lower edge 106 of the support rod 90 and the upper base 104 extends flush with a flat, upper surface 108 thereof. Correspondingly, superstructure 94 is configured with four corresponding positioning grooves 112, each having a cross section corresponding to the positioning projections 100 of the support rod 90, that is, positioning grooves 112 have a cross section of tapering with a wide opening 116 extending on a lower surface 118 of superstructure 94 and with a narrow upper part extending on the inner surface 120 of superstructure 94, configured for level support on the upper surface 108 of the support rod 90.
    It is appreciated that the trapezoidal configuration of the positioning projections 100 and the corresponding positioning grooves 112 facilitate easy assembly of the custom denture 92 on the support rod 90, with this the wide opening 116 of the positioning grooves 112 is placed on the base narrow top 104 of the positioning projections 100, thus providing a funnel-type arrangement that facilitates the placement of the custom denture on the support rod 90, however, which does not deteriorate the firm support of the custom denture 92 on the support rod 90 when completely received in it.
    Also note, the denture system collectively illustrated in Figures 5 and 6 is configured with a pin type 7 6 locking mechanism of the type revealed
    18/29 hereinafter with additional details in Figures 19A and 19B.
    Returning again to Figures 7A and 7B, a modification of the example illustrated in Figures 5 and 6 is illustrated. According to this example, the support rod generally designated with 140 is configured with positioning projections 142 that project laterally from the lingual surface and labial surface, respectively, and which extend parallel to the insertion path, as discussed above. However, the positioning projections 142 have a trapezoidal cross section (similar to the disclosure in Figures 5A and 5B), namely, having a wide bottom base 146 and a narrow top base 148, said top base extending flush with the top surface 150 of the support rod 140, and more when each of the positioning projections 142 is configured as a dovetail configuration, configured for sliding fit within the corresponding positioning grooves 156 formed in the superstructure 160 of the custom denture 162. Likewise In this way, the positioning grooves 156 have a similar configuration, in order to slide comfortably over the positioning projections 142, namely, that they are configured with a trapezoidal cross section that extends between a lower wide opening in 164 and that narrows to upwards towards the upper surface 170 of superstructure 160.
    It is appreciated that the dovetail-like positioning configuration of the grooves and projections reduces any possible tolerances between the superstructure and the integrated custom denture, while mounted on the support rod, thereby eliminating any movement.
    It is further appreciated that the positioning projection provisions that project laterally significantly increase the strength of the support rod
    19/29 to bending moments, cutting moments and torsion moments that act on the support rod, thus increasing its stability and braking. On the other hand, it is appreciated that the locations in which the superstructure is provided with positioning grooves, the overall thickness of the superstructure walls is not thinner, but, on the contrary, maintains a substantially uniform thickness.
    With additional attention being paid to Figures 8 and 9, now, yet another example of a denture system is illustrated, according to the present revealed subject that resembles, to a large extent, the configuration of Figures 5 and 6, however, wherein the support rod 180 is configured with a plurality of positioning projections generally designated 182 where, in this example, two lateral positioning projections extend from the front lip surface 184 and three positioning projections 182 extend from the internal lingual surface 186. It is observed that the positioning projections 182 are configured with a substantially straight part 190 that extends parallel to the insertion path (POI) and having a substantially rectangular cross section, although with beveled / rounded edges for minimal irritation to the individual , and there is also a lower magnification part 192.
    Correspondingly, the custom denture 190 is configured with an integrated superstructure 192 configured with corresponding positioning grooves 198, in which a lower opening of its own, designated 200, substantially flush with a lower surface 204 of the superstructure 192 is substantially wider and narrow upwards in a rectangular shape at 206 with a shape that corresponds to the corresponding positioning projections 182 and configured for comfortable mounting on it. The magnification aperture
    20/29 out of 200 facilitates easy assembly and positioning of the custom denture 190 on the support rod 180, in which, by placing the custom denture 190 and positioning it on the support rod 180, it becomes fixedly positioned and without any tolerances between them, as discussed above.
    Likewise, the positioning projections can be configured so that the bottom base is wider than the top base, both in a plane that extends along a posterior-anterior direction and in a plane substantially parallel to the support rod (Figures 10A10D).
    It should be appreciated, in connection with any of the examples discussed here, in the specification, that the number of positioning projections and respective positioning grooves can change, as well as their location and their shape and size. Likewise, a denture system can comprise several different types of positioning projections and corresponding positioning grooves, as long as the general concept of comfortable fit is present, with substantially zero tolerance between them.
    Figures 10Ά and 10B illustrate, in an enlarged scale, only a part of a support rod 220 and a part of a corresponding superstructure 222, where the positioning projections 224 configured on the support rod 220 is a combined configuration having an dovetail type, with an upper part 226 that extends substantially parallel to the POI and a lower part 228 that tapers in both a lateral and a planar direction (see also Figures 10A, 10B and 10D) and in which the groove of corresponding positioning 232 of superstructure 222 has an enlargement opening at its lower edge 236, narrowing upwards and ending at one end
    Upper 21/29 238, corresponding, in the cross section, with the positioning projections 224.
    Figures 10C and 10D are cross sections obtained along the plane of section X in Figures 10A and 10B, illustrating consecutive sets of mounting a custom denture with the superstructure integrated on the corresponding support rod, configured with a positioning groove and projections positioning, respectively.
    Although in the examples illustrated here so far, the positioning projections have been configured on the
    support rod and, respectively, the grooves in positioning have been configured in the superstructure, we following examples of Figures 11 to 14, the projections in positioning are configured in the superstructurerespectively, positioning grooves are configured on the support rod. Returning first Figures 11 and 12, it is observed that ha supportive 250 is configured in your labial face 252 with two grooves of positioning generally designated with 256 and a groove positioning 256 configured on the face lingual 258.
    Positioning grooves 256 extend parallel to the insertion path (POI) of the denture system and, in the particular example, positioning grooves 256 have an enlarged opening greater than 260, which extends from the substantially flat and soft top surface 262 of the support rod 250 and tapering downwards towards a substantially rectangular section 266, in a funnel type configuration.
    As seen in Figures 12A and 12B, the custom denture 270 is configured with an integrated superstructure 272 which, in turn, is configured
    22/29 with three positioning projections 276 configured to be received in a comfortable and tolerance-free manner within the corresponding positioning grooves 256 configured on the support rod 250. Thus, each of the positioning projections 276 is configured with a substantially lower part rectangular 280 extending from a lower surface 282 of the superstructure 272, said positioning projections 276 expanding in its upper part 286 in a manner corresponding to the shape of the respective positioning grooves of the support rod 250.
    Similar to the previous example, also in this case, the denture system is configured with a locking mechanism which, in the present example, is a locking mechanism of the pin type 76, of the type hereafter disclosed with particular reference to Figures 19A and 19B.
    Figures 13 and 14 illustrate a modification of the example illustrated in connection with Figures 11 and 12, in which the positioning grooves 290 are configured on the support rod 292 and, respectively, the superstructure 296 of the custom denture 298 is configured with projections of corresponding positioning 300 that project laterally inward, namely, in the confined space of the superstructure, in the positioning grooves 290 and the respective positioning projections 300.
    It has a tapering cross-section, namely, in which the positioning grooves 290 have a wide upper opening 304 which extends flush with the upper surface 306 of the support rod 292 and ending at a narrow lower base 308 thereof. Respectively, the positioning projections 300 of superstructure 296 extend from a narrow lower base 310 which extends flush with a lower edge 312 of superstructure 296 and extending upwards towards the upper surface 316 of the superstructure
    23/29
    296.
    In this example too, the configuration is so that the assembly of the custom denture 298 is facilitated and is guided by the funnel-type arrangement of the positioning grooves, however, by positioning the personalized denture in its final location on the support rod, it makes it is rigidly supported and with substantially zero tolerance, that is, substantially without movement between the custom denture and the behavior of the support rod.
    Returning now to Figures 15 to 18, there are illustrated different examples of denture systems, according to the subject disclosed. Figures 15 and 16 are similar in shape to the denture system revealed in connection with Figures 5 and 6, respectively, at least as far as the provision and shape of the positioning projections 330 formed on the support rod 332 and the respective positioning grooves that project laterally 336 configured in the superstructure 338 of the personalized denture 340. However, in addition to the said positioning grooves 336 and corresponding positioning projections 330, the denture system of Figures 15 and 16 still comprises a set (two, in the present example) of positioning projections projecting upwards 346 extending from the upper soft surface 348 of the support rod 332 with corresponding depressions 350 formed on the upper surface 356 of superstructure 338, in correspondence with said positioning projections 346, thereby increasing , the actual position between the respective support rod 332 and superstructure 338 with the integrated custom denture 340.
    The example in Figures 17 and 18 illustrates an arrangement that resembles that of Figures 15 and 16, however, with positioning projections and
    24/29 corresponding positioning laterally that resemble those of Figures 8 and 9, and also, when configured on the substantially flat top surface 370 of the support rod 372, there are two positioning grooves 376, while the superstructure 380 of the custom denture 382 it is configured with corresponding positioning projections 388 extending from the substantially flat upper surface 390 of the superstructure 380, configured for comfortable adjustment and reception within the respective positioning grooves 376 formed on the support rod 372. It is observed that the respective positioning grooves and positioning projections illustrated in connection with Figures 15 and 16, and 17 and 18, respectively, extend so that their side walls are parallel to the insertion path (POI) or constitute an acute angle between them, and, however, still in that the depth of the positioning groove and the corresponding height of the respective positioning projections are in order to guarantee the junction of its surface (surface to surface contact).
    As mentioned above, the denture system disclosed here previously is fitted with a locking mechanism. According to an example, the locking mechanism is a pin-type lock 76, discussed in further detail in Figures 19A (unlocked, open position) and Figures 19B (locked, closed position).
    The lock 76 comprises a housing 400 rigidly embedded within the custom denture 402, wherein said housing comprises a sleeve 404 made of or corresponding to an elastomeric or ceramic material and, in addition, the lock comprises a locking pin 408 formed with a annular travel limitation ring 412 configured to click into place by sleeve 404, said pin being displaceable between a locked position (Figure 19B)
    25/29 and an unlocked position (Figure 19A). The locking pin 408 is fitted with a substantially flat head part 414 which, in the locked position, extends in close proximity to the lingual surface 420 of the custom denture, thus causing minimal irritation to the individual, however, facilitating its retraction , for example, by the individual's nail (for this purpose, a small gap is typically configured between the inner surface of the head 414 and the lingual surface 420), the arrangement is such that the locking pin 408 is adjusted for comfortable fit within of the corresponding perforations 424 configured in the respective support rod 426, however, so that substantially no load is supported by the pin, while in the locked position.
    In some cases, the custom denture is fitted with a full perforation also in its labial face, with a corresponding complete locking perforation formed in the support rod, in which, in case of difficulty in extracting the locking pin 414, a sharp article it can be inserted through the opening (for example, a paper clip and the like) to facilitate pushing the locking pin 414 in the lingual direction to its extracted position (Figure 19A). However, this opening in the lip surface of the personalized denture is miniature and hardly visible to the eye.
    Returning now to Figures 20 and 21, a locking mechanism is illustrated, according to a different configuration from the present subject disclosed.
    The locking mechanism, generally designated 500, comprises a support rod 502 of the type included fixedly to an alveolar ridge of the individual 504 above the mucous membrane 506 by a plurality of dental implants 510.
    26/29
    The denture system 500 further comprises a personalized denture 514 that conforms to the individual's dental parameters and having the superstructure fixedly integrated within a lower surface, generally designated as 516, having a cross section that conforms to that of the support rod 502 and configured for a comfortable and tolerance-free fit on the support rod 502. The locking mechanism comprises at least one first magnet 522 received fixedly within the support rod 502 and oriented so that its North pole faces upwards and its south pole turns downwards. A disk-type manipulator 530 is received inside the custom denture 514 and is pivotally fixed on a rotation axis 532 substantially parallel to an axis of said first magnet 522. The manipulator 530 projects laterally, partially from at least one or more both between the lingual or labial face 538 and 540, respectively, and is fixedly fixed with at least one second magnet 544 oriented in an opposite direction and the first magnet 522, namely, with its south pole (S) facing down and its north pole (N) facing upwards.
    disk-type manipulator 530 is movable between a locked position (Figure 21A), in which the second magnet 544 extends substantially coaxial and above the first magnet 522, giving rise to a force of attraction that extends between them and where, as As a result, the custom denture 514 is attracted to the support rod 520 and thus will not spontaneously detach from it. The manipulator 530 is also movable in an unlocked position (Figure 21B), by rotating the disk type manipulator 530, as illustrated by the lines in arrows 550, with this, the second magnet 544 moves from its locked position above the first magnet 522, with this, the force of attraction between them captures or substantially
    27/29 decreases, thus, the custom denture 514 can be easily removed from the support rod 502.
    It is appreciated that the number of locking mechanisms of the type mentioned above, adjusted in a denture system, can vary, depending on the space provided in the denture system and, in the same way, the force of attraction can be controlled by providing magnets of different forces and, for this purpose, small, yet powerful magnets (for example, neo-medium magnets) can be used.
    In addition, it is noted that one of the first magnet 522 and the second magnet 544 can be a piece of ferrous metal configured to attract the magnetic member provided in the support rod or denture.
    In Figures 22A and 22B, a modification of the example shown in connection with Figures 20 and 21 is illustrated, in which the support rod is configured with a single magnet, as shown in the previous example, while the custom denture 560 is configured with a disk-type manipulation member 562 fitted with two magnets 564 and 566, the first oriented as in the previous example, namely, with its south pole (S) facing down and its north pole (N) facing up, and the last magnet 566 that extends with its north pole (N) facing down and its south pole (S) facing up.
    The arrangement is such that, in a first orientation of the manipulator, forces of attraction extend between the first magnet 522 of the support rod and the second magnet 566 of the custom denture, while the unlocking of the locking mechanism is facilitated by rotating the manipulator 562 to a position where magnet 564 extends above the first magnet 522, giving rise to rejection forces between them, facilitating easy extraction and removal of the denture.
    Returning now to Figures 23A-23E, it is illustrated
    28/29 a locking mechanism, according to an even different configuration, in which the support rod 600 is of the type previously disclosed here, and comprises, on its substantially flat upper surface 602, one or more projecting unlocking beams upwards 606 configured with a locking recess 608.
    The custom denture 620 is configured with the disc-type manipulator 622 that protrudes from the lingual surface 626 or the lip surface 628 or both and rotates on an axis substantially parallel to a longitudinal axis of the locking beam 606, said locking manipulator it is configured with a locking opening 632 having a wide part 634 and a narrow part 636 (Figure 23E) where the wide part 634 is at least as wide as the diameter D of the locking beam 606 and the narrow part 636 is as narrow when the recessed part d (Figure 23B) of the beam
    in locking 606. In position not locked, The custom denture 620 it is positioned on the rod in Support 600, allowing what beam 606 if design for The opening broad 634 of opening 632 (Figure 2 4A), getting, with that, the
    proper positioning and seating of the custom denture on the support rod. The locking occurs by the rotation of the manipulation member 622 in the direction of the arrow 640 (Figure 24A), with that, the narrow part 636 of the locking opening 632 locks in locking way the locking recesses 608 of the locking beam 606, avoiding, thus, the unintentional displacement of the support rod denture and eliminating any forces.
    It is appreciated that, according to any of the locking mechanisms revealed above, in the locked position, the locking mechanism does not support any loads, but, on the contrary, the custom denture superstructure
    29/29 supports comfortably on the support rod with substantially zero tolerances between them.
    Although several examples of the revealed subject have been presented, it should be understood that many changes 5 can be made in them, without deviating from the spirit of the revealed subject, mutatis mutandis. For example, the denture system, according to the subject disclosed, can be designed with a support rod configured with one or more positioning projections and one or more positioning grooves, and the superstructure correspondingly configured with one or more positioning grooves and one or more positioning projections, respectively.
