Abstract

This utility model provides a kind of banded straight silk bow supporting groove, described bracket comprises base plate and is located at the bracket body on base plate, described bracket body is horizontally set with the bracket groove that cross section is rectangle, bottom surface and the backplate surface of described bracket groove form Prevailing torque degree, banded arch wire is located in bracket groove, and wide of banded arch wire is fitted with groove bottom surface, to produce automated torque.This utility model, when being made by conventional ligation wide of banded arch wire fit with groove bottom surface, can be made tooth produce automated torque and reach normal torque degree; The change of bracket groove structure and the combination with banded arch wire, can carry out coming into line the various Tooth Movements such as leveling, adduction, torque simultaneously.The beneficial effects of the utility model are: by automated torque and synchronous Tooth Movement, reduce clinical manipulation complexity, improve Tooth Movement efficiency and accuracy, shorten the orthodontic cycle.

Description

Banded straight silk bow supporting groove

technical field:

This utility model relates to a kind of orthodontics fixed orthodontic device correcting malocclusion, especially can realize the banded straight silk bow supporting groove of automated torque and synchronize fully Tooth Movement.

background technology:

The basic structure form of current fixed orthodontic appliance is traditional edgewise appliance structure, and on bracket groove, add the bending straight arch wire groove structure of elimination three sequence, its common feature is: groove be designed to opening labiad cheek to lateral trench, the cross section of groove is the rectangle that upper-lower height is narrower than trench depth, for including the utility arch being plane leptoprosopy being bent molding with wide in, namely usually said square silk bow.It is in order to eliminate the third order bend of traditional side's silk bow, and the torque configurations that groove designs is positioned at the top and bottom of groove, realizes moving to torque the words of tooth by the moment of torsion of arch wire and top and bottom.This construction features makes the square silk bow of square-section in orthodontics moves, the mechanical mechanics property of arch wire can not be given full play to, come into line needing elastic tooth in moving and can not play desirable elasticity, and need come into line separately by other Resilient Wire material; To in control before and after the denture needing arch wire rigidity, required rigidity can not be met.Its torque produced is moved because arch wire performance can not Appropriate application, and is difficult to realize predetermined torque Tooth Movement, often needs auxiliary arch wire.Thus, the denture of currently used fixed appliance is corrected and is needed progressively to carry out, and namely comes into line leveling, adduction, torque etc., makes orthodontic efficiency lower.

summary of the invention:

In order to solve conventional brackets groove and square-section side's silk bends irrational mix performance, this utility model bracket is by the change of groove structure, make it the structural behaviour by more reasonably playing groove and square arch wire, reach the orthodontics effect of automated torque and synchronize fully Tooth Movement, clinical position efficiency can be improved.

This utility model solves the technical scheme that its technical problem adopts:

The banded straight silk bow supporting groove of this utility model, it is characterized in that: described bracket comprises base plate and is located at the bracket body on base plate, described bracket body is horizontally set with the bracket groove that cross section is rectangle, bottom surface and the backplate surface of described bracket groove form Prevailing torque degree, banded arch wire is located in bracket groove, and wide of banded arch wire is fitted with groove bottom surface, to produce automated torque.

Above-mentioned groove height is greater than 0.025 inch, and trench depth is less than or equal to 0.025 inch.

This utility model is by becoming upper-lower height size to be greater than the size of the degree of depth inside and outside it groove Cross section Design, make it to become the rectangular cross section structure that facade is greater than plane, the height being specially groove opening is greater than 0.025 inch, trench depth is less than or equal to 0.025 inch, and at groove bottom surface Prevailing torque degree, be that wide face is bent the band shape side silk bow of shaping and banded arch wire by plane in order to include in leptoprosopy, thus make banded arch wire and groove form the fixed appliance structure optimized.When making wide of groove bottom surface and banded arch wire to fit by the ligation of this structure, the automated torque that can realize tooth moves, and the more existing bracket of the expression of Prevailing torque degree can be made more accurate.On the other hand, banded arch wire denture words to favorable elasticity be conducive to the movement of straightening of teeth, arch wire is conducive to controlling the stable of biteplane and laminating opening in the sagittal rigidity of denture, thus can start namely to carry out adduction denture at first appliance of installing, and while adduction, realize coming into line and flattening of tooth.The change of this bracket groove structure and the combination of bending with band shape thereof, can carry out coming into line the various Tooth Movements such as leveling, adduction, torque simultaneously, thus come into line when changing existing fixed appliance treating tooth leveling, adduction, torque in order proceed step by step rescue program.This utility model only need use a main arch wire, without the need to using auxiliary bow, and seldom needs to change arch wire.Thus make clinical manipulation more be simple and easy to grasp.

The beneficial effects of the utility model are: by automated torque mechanism and synchronize fully Tooth Movement mechanism, solve existing fixed orthodontics Tooth Movement from fixed appliance stuctures and properties mechanism to be undertaken by intrinsic program, efficiency is low, the uppity problem of degree of accuracy.Decrease the complexity of clinical manipulation, improve Tooth Movement efficiency and accuracy, shorten the orthodontic cycle.

detailed description of the invention:

The banded straight silk bow supporting groove of this utility model, the bracket body 1 that described bracket comprises base plate 5 and is located on base plate, described bracket body is horizontally set with the bracket groove 2 that cross section is rectangle, bottom surface 201 and the backplate surface 501 of described bracket groove form Prevailing torque degree 8, banded arch wire is located in bracket groove, and wide of banded arch wire is fitted with groove bottom surface, to produce automated torque.

In FIG, bracket body (1) and base plate (5) are bonded bracket entirety, bracket body (1) are designed with groove (2), positioning mark (3), bracket tie wings (4), vertical holes (6) and bracket substrate (7).

When bracket is adhered to tooth labial surface according to positioning mark (3), its position as shown in Figure 2; The angle that the bottom surface of bracket groove (2) and backplate surface 501 are formed, as Fig. 3, is Prevailing torque degree (8).

Fig. 5,6, the bottom surface of groove (2) namely forms banded arch wire torque mechanism (10) with the banded long limit facade bending cross section (9) automatically by conventional ligation bracket tie wings (4), when torque degree reaches Prevailing torque degree (8), both shown as the relation (11) of groove and banded arch wire when normal torque is spent, now Tooth Movement is to normal lip inclination.This torque mechanism is produced automatically by conventional ligation.
