Abstract

The utility model relates to an arc-shaped groove bracket which comprises a bracket body and a groove formed in the bracket body. The arc-shaped groove bracket is characterized in that the groove is of an arc-shaped structure and matched with the radian of an arch wire. The straight groove structure of an existing bracket to locate the arch wire is changed, the groove is designed to be the arch-shaped structure, the arch wire can be matched with the groove, matching clearances are reduced, and necessary conditions are provided for fine adjustment of the position of teeth, clinically, the arch wire does not need to be bent at each tooth position, and the arch wire can be conveniently located, adjusted and bonded in the groove.

Description

A kind of arc-shaped trench bracket

Technical field:

This utility model belongs to dental orthotic field, particularly a kind of arc-shaped trench bracket.

Background technology:

Existing orthodontics is raw silk rings shape with the groove of bracket, that is to say as straight groove structure, but arranging due to human teeth is an arcuate structure, so just there will be in the time that arch wire size and groove approach and cannot insert, clinically, often need each tooth position row bending arch wire again, operation easier is large, also time and effort consuming.And if allow arch wire insert smoothly, must strengthen groove, this there will be again edge clearance excessive, is unfavorable for the intense adjustment to tooth position.How to overcome this contradiction, provide a kind of arch wire to be easy to into groove, and can reduce the clearance scheme of arch wire and groove, become the object of this utility model research.

Summary of the invention:

The purpose of this utility model is that a kind of groove of design is arcuate structure, inserts and form pinpoint arc-shaped trench bracket for arc arch wire.

Technical solutions of the utility model are achieved in that a kind of arc-shaped trench bracket, comprise the groove of offering on bracket and bracket, it is characterized in that groove is arcuate structure, coincide with arch wire radian.

Described bracket is fixed-wing bracket, comprises the wing of determining of bracket seat and disjunctor, and described arc-shaped trench is by bracket seat and two fixed interplane spaces that form.

Described bracket is Support slot with movable wings, comprises fixed-wing and is movably set in the movable wing on fixed-wing; Described movable wing has the tie wings of pin and disjunctor, and this tie wings top is provided with ligature hook and arch wire lid; Described arc-shaped trench is the space being formed by described arch wire lid, tie wings and pin.

This utility model changes the straight trough groove structure of existing bracket position arch wire, and groove is designed to arcuate structure, and arch wire can be coincide into groove, reduces and coordinates clearance, for the intense adjustment that reaches tooth position provides essential condition; Clinically, also remove bending arch wire without each tooth position, arch wire can be more convenient enters groove location, adjustment and ligation again.

Detailed description of the invention:

Embodiment mono-:

See figures.1.and.2, the bracket in this example is fixed-wing bracket, and what comprise bracket seat 1 and disjunctor determines the wing 2, and arc-shaped trench 3 is to determine by bracket seat 1 and two space forming between the wing 2; Can coincide with arch wire 6 radians, reduce clearance, reach intense adjustment.

The fixed-wing bracket of this legend, also applicable in Support slot with movable wings, as the structure of fixed-wing, or the improvement of traditional fixed-wing bracket.In this legend, the moulding of bracket is applicable to the rectification of tongue side.

Embodiment bis-:

With reference to Fig. 2, Fig. 3 and Fig. 4, the bracket in this example is Support slot with movable wings, comprises fixed-wing 4 and is movably set in the movable wing 5 on fixed-wing 4; This movable wing 5 has the tie wings 52 of pin 51 and disjunctor, and these tie wings 52 tops are provided with ligature hook 53 and arch wire lid 54; Described arc-shaped trench 3 is the spaces that formed by described arch wire lid 54, tie wings 52 and pin 51; In this legend, arc-shaped trench 3 is to arch upward toward arch wire lid 54 1 sides, as Fig. 5, is applicable to needing of facing rectification.

Embodiment tri-:

With reference to Fig. 6 and Fig. 7, this exemplary construction is same with example two, and just arc-shaped trench 3 is recessed toward pin 51 1 side pressures, as Fig. 7, is applicable to needing of tongue side rectification.
