    CLAMPING DEVICE FOR A CLASP TECHNICAL FIELD
    The invention relates to a clamping device for a brace for transmitting prestressable spring forces on at least one in the lower or upper jaw in its position to be regulated tooth, the hie door has at least one connecting element.
    STATE OF THE ART
    Such jigs are used, inter alia, to correct the position of one or more teeth, for example to make room for an orderly alignment of the other teeth. In this context, WO 2009/071492 A2 an anchoring device for a tooth and / or jaw regulation is known, which is shown in its application with two braces, one of which in the palate area and the other around the outer periphery of the teeth of an upper jaw are arranged. Both braces have a seen in plan view horseshoe-shaped basic body in the form of tension wires, which is adapted to the individual jaw shape.
    The located in the palate area basic body of a brace is attached centrally with the anchoring device in the form of a bone screw on the upper jaw, whereas the two end portions of this brace are each firmly connected to a connection element which is provided on a pushed over a molar circular clamp , The outer braces in turn is also in each case fixed with its end portions of the said round braces of the molars via a connection element, but sliding, namely the braces on both sides in each case via a provided at this fixture for transmitting prestressable spring forces according to the arrows indicated there on which can act on the teeth to be moved.
    Since braces are mainly used in young patients and in turn are still growing, the jigs of the braces - which usually have to be worn over a longer period - often (for example, every 4 to 6 weeks) readjusted or even exchanged. These measures can be very time consuming due to the fixed installation of the braces on the respective teeth to be regulated, especially since the braces in the oral or oral cavity area are not easily accessible, moreover, a treatment with permanently installed braces is already relatively expensive anyway.
    OBJECT OF THE INVENTION
    This is where the invention, which is based on the object for a jig of a brace to create a clamping element, with which it is possible that this quickly and easily attached to the patient itself, that is fixed and pre-tensioned or post-tensioned can.
    SOLUTION OF THE TASK
    This object is achieved according to the invention in an advantageous manner that the tensioning device has a clamping element, the tooth side in the connection element plug-or hooked and tooth rack side is slidably formed on the braces.
    ADVANTAGES OF THE INVENTION
    As a result, it is advantageously possible with the tensioning element to pull this out, for example, on the connection element or to hang from this, then to make the braces 1/9 Austrian Patent Office AT12 663U1 2012-09-15 with the clamping device in this area more accessible and thus easier to readjust. Then it can then be easily attached to the respective connection element again. It is not necessary to unhook the tensioning element.
    Thus, the main advantage of the invention is that the entire system (clamping device with braces and clamping elements) can be preassembled and adapted to a gypsum or plastic model created by the patient, so that this in a further step without further corrections and processing of Overall system can be inserted into the jaw of the patient.
    Another essential advantage of the invention is that the attending physician, for example, the orthodontist can apply the entire system only by plugging and screwing. There is no need for a laboratory in which the items must be made. The present kit provides an easy to use system.
    The overall system also has the advantage that both by a tensile or compressive arrangement (direction in which the clamping element presses or pulls) causes the tooth to be positioned is pressed or pulled in the right direction.
    According to the present invention, it is expedient if the clamping elements on the side of the connecting elements each have a tongue-like portion and on the side of the brace have a sliding bush and the connecting elements to form a plug connection with the respective clamping element a pocket-like projection for receiving from its tongue-like portion. As a result, each connector can be made advantageous by a linear telescoping of the tongue-like portion in the pocket-like projection, which is very accommodating the space in the oral cavity area, especially since each clamping element is formed on the braces linearly displaceable on the braces by means of its slide bushing.
    Further, it may be expedient if the clamping element is formed on the side of the tongue-like portion corresponding to a mirror-inverted sieves whose transverse leg is the tongue-like portion.
    The clamping element can be made at the same time on the side of the tongue-like portion as a whole as a flat portion, similar to a small plate that takes up little space but is still stable in its longitudinal and transverse directions.
    The tongue-like portion opposite end portion can be fixedly connected to the sliding bush, in such a way that this end portion extends coaxially with the sliding bush, wherein the end portion in this case expediently has a length corresponding to the length of the sliding bushing.
    For attachment of possible other dental equipment such as binding wires, it may be advantageous if the end portion of the flat portion of the clamping element is formed on the side of the tongue-like portion with a right angle or has an additional hook member, which is then much smaller than that Whole flat portion of the clamping element is, wherein the tongue-like portion may be formed with a corresponding transverse web mirrored to this.
    As a further attachment for the said aids can also be provided that the end portion of the flat portion of the clamping element in the axial direction relative to the additional hook member has a bore. Finally, it is advantageous if the tongue-like portion of the clamping element and the crosspiece of the additional hook member are rounded at the ends, so that hereby a possible risk of injury is reduced and at the same time the tongue-like portion can be easily inserted into the pocket-like projection on the connection element.
    The sliding bushing of the tensioning element is an integral part. This sliding bush is either soldered or welded to the section. It can also be a one-piece 2/9 Austrian Patent Office AT 12 663 Ul 2012-09-15

    DESCRIPTION OF THE EMBODIMENTS
    The jaw part shown spatially in Fig. 1 (for example, a lower jaw)-designated 1 - has a series of teeth, of which the two molars 2 and 3 are to be displaced with respect to their position to the whitening teeth 3 and 4, Why a brace 6 is provided in a U-shaped curved shape. Furthermore, it should be effected that the jaw is stretched accordingly, so that the individual teeth get the necessary space.
    The brace 6 consists of a tensioning wire and is centrally attached via a bracket 7 with two fixing screws 8 on the jawbone and has free legs 9 and 10, on each of which a clamping device 11 is pushed, which is a locking member 12 with a screw 13, a compression spring 14 and as a first embodiment of an inventive clamping element 15 includes.
    The tensioning element 15, as shown on the right side of the jaw part 1, is connected by a releasable plug connection with the molar tooth 2, on the one hand pushed over this a ring clamp 16 with connecting elements 17 and 18 and on the other hand has the clamping element 15th for this purpose, a tongue-like portion 19, which is then inserted into the connecting element 18, which is pocket-shaped.
    The tongue-like portion 19 belongs to a flat portion 20, which is formed corresponding to approximately a mirror-inverted sieves. This has a tongue-like portion 19 opposite end portion 21 which extends coaxially with a sliding book 22 and is fixed thereto, wherein the end portion 21 has a length corresponding to the length of the sliding bush 22. Further, the end portion 21 on the side of the tongue-like portion 19 has a finger-like hook member 23 facing thereto.
    2-5 are shown as the second and third embodiments, two alternative clamping elements, the matching with the clamping element 15 in Fig. 1 parts have the same reference numerals.
    In Fig. 2 and 3, a clamping element 24 is shown with a flat portion 25, the end portion 21 terminates without an additional hook member 23. Whereas in FIGS. 4 and 5, a tensioning element 26 is shown, which has a flat portion 27, at the end portion 21 on the side of the tongue-like portion 19, an additional hook member 28 is provided. This hook member 28 is compared to the flat portion 27 of the clamping element 26 is substantially smaller and compared to the tongue-like portion 19 with a transverse web 29 mirror-inverted formed to this.
    Further, the flat portion 27 of the clamping element 26 still has a bore 30 which is arranged transversely to the axial direction of the sliding bush 22 in this relative to the additional hook member 28.
    Finally, the tongue-like portions 19 of the clamping elements 15 and 26 and the transverse web 29 of the additional hook member 28 are rounded end rounded.
    INDUSTRIAL APPLICABILITY
    In the jaw part 1 shown in Fig. 1, for the regulation of, for example, the molars 2 and 3, first the braces 6 are adapted in their u-shaped form the course of the teeth of the jaw 1 and then with two fixing screws 8, which through the Bracket 7 are inserted, centered on the jawbone as a kind of geometric resistance point secured against rotation. The fixing screws 8 engage in previously implanted bone screws and interact with them. Then the ring clamp 16 are placed over the molars 2 and 3 to be regulated, which can be done before the insertion of the brace 6.
    On the free legs 9 and 10 of the brace 6 is then in each case a tensioning device 11 quasi threaded, which in turn can be done before the attachment of the brace 6. As can be seen in the example of the right side of the jaw part 1 (but in an already biased state), the clamping element 15 was inserted with its tongue-like portion 19 in the pocket-shaped connection element 18 and then pushed the locking member 12 against the restoring force of the compression spring 14, so whose individual turns lie on each other.
    In this state, then the set screw was tightened so that the tensioning device 11 remains biased, that is on the molar 2 permanently exerts a lateral thrust force, so that this medium-term changes its position with respect to the white tooth 4. The force thus acts in the direction of the white tooth 4. However, it is also possible with the same arrangement as shown in FIG. 1 form a tensile force in the direction of the incisors, in which the spring in a connecting element 15 or in a bore 30 (Fig. 4) is hooked and the locking member 12 is guided in the direction of the incisors.
    The further connection element 17 serves to insert more rubbers or springs. However, it is not necessary for the present application and could not be present.
    On the left side of the jaw part 1, as an example, the tensioning device 11 is shown in a state before the compression spring 14 has been biased.
    Overall, a simplified attachment of the brace 6 to the teeth to be regulated 2, 3 has become possible through the connector between the clamping and connecting element 15, 18, which then experienced by the respectively interposed compression spring 14 a permanent thrust, so this due to the sliding bushes 22 can perform a pushing movement parallel to the legs 9, 10 of the brace 6. As soon as this thrust decreases in, for example, 4 to 6 weeks, the tensioning device 11 can be re-tensioned in a simple manner. At the same time, the additional hook members 23, 28 provided as an alternative to the clamping elements 15, 26 as well as the bore 30 can be fastened with additional aids such as wires. 9.4
