Abstract

The utility model is a set of dental orthodontic straight wire bracket, which comprises 20 brackets for teeth positions, wherein, each bracket includes a bracket body and a base plate, the bracket is provided with a marker, a ligation wing and a working groove, and the data of the axis tilt angle, the torque angle, the height of the base, the proximal, distal and median radians, the radian between the gingiva and the jaw, the distal and median compensation angles are designed in accordance with the Chinese normal jaws, thus the utility model is suitable for the Chinese dental morphology. The clinicians do not need to bend or adjust the wire during the whole orthodontic process, till the end of the orthodontic treatment. The straight wire bracket not only provides a better clinical orthodontic tool for the domestic orthodontic doctors, but is also suitable for the majority of the Chinese people, thereby making the face of the patients be more beautiful and harmonic after the orthodontic treatment.

Description

The just abnormal straight silk bow supporting groove of one cover tooth section

Technical field

This utility model relates to the wrong jaw abnormality of oral cavity denture and corrects the orthodontic bracket 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.

Orthodontic bracket is rescued the principle difference according to fixed appliance, roughly has following several: side's silk bow bracket, and the ROTH straight silk bow supporting groove, MBT slip bracket, the ALEXANDER straight silk bow supporting groove, the Tip-Edge bracket, or the like.Side's silk bow bracket is development fixed appliance parts early, and the doctor need bend and adjust arch wire in chair a large amount of time of other cost when operation, and working strength is big, and efficient is low.Other bracket such as ROTH, or bracket such as MBT is preset at three sequence bendings on the bracket, needn't bend arch wire, only needs that a straight arch wire is directly embedded the bracket groove at every turn when changing arch wire and gets final product.Improved clinical efficiency greatly, made a just abnormal doctor to be subjected to increasing just abnormal doctor's welcome simultaneously for a plurality of patient's services.

But, above-mentioned all fixed appliances are all by the just abnormal doctor's design of Hesperian specialty, the data of its designing institute collection obtain on the structure of statistical analysis westerner tooth and morphological basis, and therefore, these brackets are more suitable for westerner's orthodontic therapy.The China doctor often will do some adjustment to the angle of torsion or the axial rake of single tooth in each patient's the later stage of rescuing.

Summary of the invention

The purpose of this utility model provides the just abnormal straight silk bow supporting groove of a cover tooth section that is suitable for Chinese's tooth form that the wrong jaw abnormality of a kind of denture is corrected usefulness.

The just abnormal straight silk bow supporting groove of a cover tooth section of the present utility model, bracket with 20 tooth positions, each bracket comprises supporter groove and substrate plate, supporter groove has gauge point, tie wings and work groove, and the offset angle data are as follows to radian with far for the axial rake of each tooth position bracket, angle of torsion, end height, nearly middle radian far away, gum jaw:

The bracket of a whole set of 20 tooth positions of the present utility model corresponds respectively to 20 teeth in the human body denture, comprises the buccal tube of grinding one's teeth in sleep, and buccal tube is ground one's teeth in sleep corresponding to the 1st and the 2nd.Bracket can be made by corrosion resistant metal, pottery or plastic or other material.When using stainless steel material to make, through digital control processing, one piece casting, powder injection or draw supporter groove and the stainless (steel) wire base plate dialled after being shaped firmly to weld together, then carry out surface treatment, make surface roughness value Ra≤0.05 μ m.Bracket also can adopt powder injection forming or casting method integral body to create, and makes it to be integral the formula bracket, and base plate adopts the adhesion strength that groove or alternate manner make to be increased with facing.

And customized, in whole strong process, until rescuing end, the clinician need not to bend or adjust arch wire to straight silk bow supporting groove of the present utility model at Chinese normal jaw standard.This straight silk bow supporting groove is not only rescued instrument for domestic just abnormal doctor provides a kind of better clinic orthodontic, and is fit to the compatriots of the overwhelming majority, makes patient rescue rear face coordination more attractive in appearance.

Description of drawings

Fig. 1 is the structural representation of the single straight silk bow supporting groove of this utility model, and wherein: (A) figure is the front view of bracket, and (B) figure is the side view of bracket, and (C) figure is the vertical view of bracket.

The specific embodiment

With reference to Fig. 1, each bracket comprises supporter groove 1 and substrate plate 2, and underlined point 3, tie wings 4 and work groove 5 are identical with common bracket on the supporter groove.Basilar part adopts network structure, can increase the contact area of bracket and crown surfaces, thereby improves the adhesion strength between bracket and the dental surface.If the axial rake degree is α, torque angle is β, and the substrate plate hight is h, and nearly middle radian far away is a, and the gum jaw is b to radian, and middle offset angle far away is γ.The axial rake of each tooth position bracket, angle of torsion, end height, near far away in radian, gum jaw to radian and far away in the offset angle design data as shown in table 1:
