Abstract
The utility model relates to a dental orthopedic metal supporting groove to rectify the abnormity of malocclusion which comprises a working groove, a ligature foil, a groove supporting body and a baseboard, and is characterized in that the baseboard is provided with at least two metal silk screens with the grids overlapped together. Such dental orthopedic metal supporting groove has at least two layers of metal silk screens at the base to form a frame space, so that the screen silk is wrapped by the binding admixture, thereby increasing the contact area between the binding admixture and the base of the supporting groove. After the binding admixture enters the base of such supporting groove and solidifies, the binding admixture produces a binding force with the tooth surface, thereby improving the solidification function of the supporting groove in the course of rectifying the abnormity of malocclusion.
Description
Technical field
This utility model relates to the wrong jaw abnormality of a kind of oral cavity denture and corrects the just abnormal metal bracket of tooth section of usefulness.
Background technology
Tooth section orthodontic bracket is the important composition part of mouth cavity orthodontic fixed appliance, orthodontic bracket is fixed on the facing, arch wire passes groove and fixes by tie wings and bracket, and the power of rescuing of arch wire is delivered to tooth by bracket in the orthodontic treatment process of denture, makes tooth produce moving of expection.
Used bracket was made up of supporter groove and substrate plate during present domestic mouth cavity orthodontic was clinical, and supporter groove has work groove, tie wings and ligature furrow, and its substrate is dove-tail form and monolayer net bottom.In clinical bonding operation, the adhesion strength of bracket and facing depends on the structure kenel of bracket substrate plate to a great extent.Present this substrate plate structure bracket occurs from the phenomenon that facing comes off through regular meeting in the orthodontic treatment process, this situation occurs, makes patient and doctor feel trouble deeply on the one hand, has also influenced treatment cycle and effect on the other hand.
Summary of the invention
The purpose of this utility model provides a kind of and the high just abnormal metal bracket of tooth section of facing adhesion strength.
The just abnormal metal bracket of tooth section of the present utility model comprises supporter groove and substrate plate with work groove, tie wings and ligature furrow, it is characterized in that being fixed with at least on substrate plate the staggered metal gauze that coincides of two-grid.
The just abnormal metal bracket of tooth section of the present utility model, because substrate has double layer of metal silk screen at least, form a frame-type space, make bonded dose of parcel of twine, increased the contact area of binding agent and bracket substrate, binding agent promptly produces firm adhesion with facing after entering the substrate curing of this kind bracket, can improve the firm effect of bracket in just abnormal process.
Description of drawings
Fig. 1 is the just abnormal metal bracket structural representation of tooth section of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
With reference to accompanying drawing, the just abnormal metal bracket of tooth section of the present utility model comprise have work groove 3, the supporter groove 1 and the substrate plate 2 of tie wings 4 and ligature furrow 5.In the illustrated example, on substrate plate 2, be welded with the staggered metal gauze 6 that coincides of two-grid.Its grid can be a random geometry, and usually, the order number of used metal gauze is 20～200 orders, and the silk footpath of metal gauze is 0.05～2.0mm, and the cross section in silk footpath has random geometry.The order number of silk screen and silk footpath can be identical, also can be inequality.Bracket is to be made by austenitic stainless steel or its metal of base, has the tooth of corresponding different sizes of all size and different tooth position.
Claims (3)
1. the just abnormal metal bracket of tooth section, comprise have work groove (3), the supporter groove (1) and substrate plate (2) of tie wings (4) and ligature furrow (5), it is characterized in that on substrate plate, being fixed with at least the staggered metal gauze (6) that coincides of two-grid.
2. by the just abnormal metal bracket of the described tooth of claim 1 section, the order number that it is characterized in that metal gauze (6) is 20～200 orders.
3. by claim 1, the just abnormal metal bracket of 2 described tooth sections, it is characterized in that the silk footpath of metal gauze (6) is 0.05～2.0mm.
