Abstract

The utility model disclose a dental appliance which comprises a bracket fixed on the enamel surface; wherein one side of the bracket is in contact with the enamel surface and its other side is provided with an arch wire bracket, the arch wire bracket is provided with an arch wire, the two longitudinal sides along the arch wire bracket are provided with a groove, and the groove is provided with an arch wire fixed clamp which fixes the arch wire on the bracket. The arch wire fixed clamp is provided with a head end and a tail end, the projection of the whole of the arch wire fixed clamp on the level plane forms a lapjointed square ring in the end, the two longitudinal sides are clamped in the groove, one side relative to the head end in the transverse direction is provided with a semi-ring convex ring clamped on the arch wire surface, the head end is provided with a hook, the hook is clamped on the arch wire surface, and the tail end is clamped in the adjacent side between the arch wire and the bracket. The utility model has the simple operation and the arch wire fixed clamp can be repeatedly used; the replacement of the arch wire is convenient and rapid, which can save materials and reduce the cost.

Description

A kind of orthadontic appliance

Technical field

This utility model relates to a kind of medical apparatus and instruments, is a kind of orthadontic appliance specifically.

Background technology

A kind of advanced medical apparatus and instruments of the correction deformity tooth of fixed appliance, it by band, bracket, buccal tube, rescue arch wire and some other adnexaes are formed, wherein rescue arch wire and be by the finer wire ligation on bracket and play a role.Because the correction deformity periodontal phase is longer, generally need 1-2, and just needed to change arch wire every 1-2 month, each arch wire of changing all needs the finer wire that the ligation arch wire is used is untied, and will rescue arch wire again and use the finer wire ligation on bracket, the finer wire that the ligation arch wire is used is with once just still falling, and the one, troublesome poeration, the 2nd, waste material.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of simple to operate, fixing reusable orthadontic appliance of material of using of arch wire.

For solving the problems of the technologies described above, this utility model comprises the carriage that is fixed on the enamel surface, one side of carriage contacts with enamel surface, opposite side has the arch wire bracket, in the arch wire bracket arch wire is installed, be provided with groove along the vertical both sides of arch wire bracket, its construction features is the arch wire that arch wire is fixed on the carriage to be installed in the described groove fix card.

Described arch wire holding clamp has a head end and a tail end, the side annular that project into end overlap joint of its integral body on horizontal plane, vertically both sides are installed in the described groove, has the semi-circular bulge loop that is installed on the arch wire surface in a horizontal side relative with head end, head end has a crotch, this crotch is stuck in the surface of arch wire, and tail end snaps in an arch wire side adjacent with carriage.

The fixing card of described arch wire is formed by finer wire bending successively.

After adopting said structure, when changing arch wire, as long as the tail end of the fixing card of arch wire is extracted out from arch wire is inboard, the fixing card of arch wire can be taken off, the arch wire that more renews, and when installing, the crotch of arch wire fixed chuck end is stuck in the surface of arch wire, walk around the groove on the arch wire bracket successively, then its tail end is snapped in an arch wire side adjacent with carriage and get final product, it is simple to operate, and arch wire fixedly card can repeatedly use, the replacing arch wire is convenient, fast, and economical with materials reduces cost.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation that Fig. 1 overlooks;

Fig. 3 is that the A-A of Fig. 1 is to view.

The specific embodiment

With reference to accompanying drawing, this orthadontic appliance comprises the carriage 1 that is fixed on the enamel surface, one side of carriage 1 contacts with enamel surface, opposite side has arch wire bracket 4, arch wire 3 is installed in the arch wire bracket 4, be provided with groove 6 along arch wire bracket 4 vertical both sides, the arch wire that arch wire 3 is fixed on the carriage 1 be installed in groove 6 fix card 2.The fixing card 2 of this arch wire has a head end 7 and a tail end 8, the side annular that project into end overlap joint of its integral body on horizontal plane, vertically both sides are installed in the described groove 6, has the semi-circular bulge loop 5 that is installed on arch wire 3 surfaces in a laterally relative side with head end 7, head end 7 has a crotch, this crotch is stuck in the surface of arch wire 3, and tail end 8 snaps in the adjacent side of arch wire 3 and carriage 1.The fixing card of arch wire 2 is formed by finer wire bending successively, and its material is the nitinol alloy wire of the about 0.5mm of diameter, with the maintenance better elastic.
