Abstract

The invention provides a kind of sleeve pipe groove to interlock the adjustable bracket of torque, is related to dental orthotic field.The tooth rectification bracket includes being available for rescuing the sleeve pipe that arch wire passes through and the groove with bracket seat；The cylindrical sleeve outer wall and the groove inwall of cylinder are respectively equipped with along the equally distributed rack of major axis, described sleeve pipe and insert the groove and form interlocking；Described sleeve pipe interior wall construction is close with adding torque arch wire external structure, it is ensured that the arch wire slidably, and can ensure that the arch wire can not rotate in described sleeve pipe in described sleeve pipe；In lip cheek to horizontal opening, width is advisable the groove of the bracket with rescuing maximum model arch wire needed for just including；The length of described sleeve pipe is consistent with the groove length.The tooth rectification bracket of the application solves the nonadjustable technical problem of straight arch wire orthodontic bracket correction angle.

Description

Sleeve pipe groove interlocks the adjustable bracket of torque

Technical field

The invention belongs to dental orthotic field, more particularly to a kind of adjustable tooth rectification bracket of torque.

Background technology

During traditional edgewise appliance is rescued, arch wire will carry out three kinds of sequence bendings.The first horizontal bend, certainly Determine the trend of tooth horizontal direction；Second is that axle inclines song, is the bending in arch wire vertical direction, determines the shaft rake of tooth； The third is torque bending, by the torsion using square filament length axle as axle center, come determine tooth words to gradient.

Straight wire appliance generally used now effectively eliminates first, second, third sequence by the improvement to bracket Row bending.First order bend is eliminated by adjusting the thickness at each bracket bottom；Eliminated by the default axial rake of bracket Second order bend；Third order bend is eliminated by bottom land or groove preset torque angle.Thus eliminate curved to arch wire The program of system three kinds of sequences bending, make to rescue more convenient.

There is also deficiency while straight wire appliance is brought convenience to us.All it is by bracket preset thickness Complete to rescue with angle, and the thickness of bracket and angle are all non-adjustable, so will result in not accurate enough the and discomfort rescued, It is nonadjustable especially by bottom land or groove preset torque angle, strength is also non-adjustable caused by torque, can so give patient Bring pain or discomfort.And for words to the big patient of gradient, arch wire be difficult into groove, can thus give rescue bring it is tired It is difficult.

Thus, the present invention devises a kind of sleeve pipe groove interlocking adjustable bracket of torque and efficiently solves above mentioned problem.

The content of the invention

It is an object of the invention to design a kind of sleeve pipe groove interlocking adjustable teeth orthodontic bracket of torque, solves straight arch wire The uncontrollable technical problem of orthodontic bracket correction angle.

The present invention devises a kind of sleeve pipe groove interlocking adjustable bracket of torque, including be available for rescuing sleeve pipe that arch wire passes through and Groove with bracket seat.It is characterized in that described sleeve pipe outer wall and groove inwall are cylinder, and in sleeve outer wall and groove Wall is respectively equipped with along the equally distributed rack of major axis, inserted after described sleeve pipe arbitrarily rotation the groove can tight connecting formed Interlocking.

Described sleeve pipe is cylinder tubular structure, described sleeve pipe pipeline supply needed for rescue arch wire by and in the pipeline Wall construction with by the pipeline arch wire external structure of torque can be added close, it is ensured that the arch wire can in described sleeve pipe Slidably, and ensure that the arch wire can not rotate in described sleeve pipe.

The groove of the bracket is cylindrical tubular structure, in lip cheek to horizontal opening, is easy to arch wire to be put into from buccal labial surface, Width is advisable with rescuing maximum model arch wire needed for just including.

The described sleeve pipe groove interlocking adjustable bracket of torque, it is characterized in that the length of described sleeve pipe and the length of the groove It is consistent.

The present invention provides the described sleeve pipe groove interlocking adjustable bracket of torque, and the bracket bonding is in the buccal labial surface of tooth, groove Ditch parallel to level to, notch horizontal opening in lip cheek to, described sleeve pipe be enclosed in advance with its match for the bow rescued On silk, the groove for including the bracket again for the arch wire rescued, then described sleeve pipe inserted in described groove one end, and Formed and interlocked in groove.When needing to add torque to the arch wire, need to only rotate to an angle described sleeve pipe the insertion mortise It can reach in ditch and accurately rescue purpose, the arch wire can be locked in again in the bracket, reach the effect of ligation.

Brief description of the drawings：

Combining specific legend by taking square silk bow as an example below, the invention will be further described：

Fig. 1 is that sleeve pipe groove interlocks the adjustable bracket groove cross-sectional view of torque；

Fig. 2 is that sleeve pipe groove interlocks the adjustable bracket sleeve pipe cross-sectional view of torque；

Fig. 3 is that groove sleeve pipe interlocks cross-sectional view；

Fig. 4 is that square silk passes through sleeve pipe cross-sectional view；

Fig. 5 is that square silk is locked in groove cross-sectional view by sleeve pipe；

Fig. 6 adds cross-sectional view after torque to square silk.

Embodiment

Technical scheme is clearly fully described by with reference to accompanying drawing by taking square silk bow as an example below.

Referring to figs. 1 to Fig. 6, the sleeve pipe groove interlocking adjustable bracket of torque includes groove 1 and sleeve pipe 2；The back side disjunctor of groove 1 has Bracket seat 6, the inwall of groove 1 is cylinder, provided with along the equally distributed rack 3 of major axis；The outer wall of sleeve pipe 2 is cylinder, provided with edge The equally distributed rack 4 of major axis；Groove 1 is inserted after the arbitrarily rotation of sleeve pipe 2 can tight connecting formation interlocking such as Fig. 3.

Groove 1 is advisable in lip cheek to horizontal opening 7, width with the just side's of including silk 8.

The cross-sectional structure of the sleeve opening 5 of other sleeve pipe 2 is close with the cross-sectional structure of square silk 8, is rectangle, so , can only be in sleeve pipe 2 slidably after square silk 8 passes through sleeve pipe 2, and such as Fig. 4 can not be rotated in sleeve pipe 2.

With initial reference to Fig. 4 by the square threading 2 of silk 8 in this example, then square silk 8 included in groove 1, finally by sleeve pipe 2 Insert groove 1 and pin such as Fig. 5.As long as being inserted into after sleeve pipe 2 is rotated to an angle in groove 1, square silk 8 can form torque and reach To the purpose rescued such as Fig. 6.
