Abstract

A brake of an orthodontic balancing appliance is in a T-like shape of a conventional brake and an L-like shape of a lingual brake. The conventional brake is composed of a brake cap and a brake body, wherein the brake cap is an arc irregular body, the brake body is an asymmetrical cuboid, two ends of the brake cap are free, the free two ends are symmetrical in size, the edge of the brake cap is an arc cap smooth region, four triangular friction ditches are formed on the front surface of the brake body, and the brake apex of the brake body is an arc smooth surface. Two sliding crests are formed on the back of the brake body and are parallel to two side edges of the brake body. The lingual brake is smaller than the conventional brake, a force applying convex is located at the upper part of the brake body surface, the force applying convex is of a prominent shape, the side surface of the force applying convex is of a mushroom-like shape, and the shape of the brake body of the lingual brake is identical to that of the brake body of the conventional brake. The positions and shapes of the brake caps and force applying convexes as well as the sizes of the conventional brake and the lingual brake are different.

Description

The damper brake of mouth cavity orthodontic balance appliance

Affiliated field:

Be to be used for the arresting parts of tooth body in the mouth cavity orthodontic field balance rectification system.

Background technology:

In the mouth cavity orthodontic field, the most often use the rectification system of damper brake in the Begg filament rectification system, it promptly is in arresting process that there is a common shortcoming in the damper brake in Begg rectification system; The relative tooth body of bracket can not play whole machine balancing braking, though its reason has the situation of tooth body self unstable, the groove wing design that bracket lacks the balance adjustment also is that it occurs in arresting process inhomogeneous like diastema; Move the nearly medium dip far away of tooth body; Syndromes such as major axis inclination, though can adjust the deficiency of appearance through auxilliary bow, its shortcoming at first is a trouble; The other activity duration of chair is longer; Next is that action effect lacks accurately, this shows damper brake bracket in the Begg filament bow rectification system.Correct between the tooth body three and in the process of orthodontic procedure, have error, can not in the process of operation, form tacit agreement and influence mobile tooth and the relation between the braking tooth in the correcting process, cause influencing the rectification program at last, the improvement time extends.

Summary of the invention:

According to physical friction power principle and balance appliance bracket form; The damper brake form of balance appliance is conventional type " T " shape and two kinds of forms of tongue side damper brake class " L " shape; Concrete condition is following: balance appliance conventional brake lock is made up of lock medicated cap and lock body two parts; The form of lock medicated cap is the arc irregular body, the lock body be shaped as asymmetric cuboid.Lock medicated cap positive curved, the two ends of lock medicated cap are free shape, and free two ends size is symmetrical; 5 millimeters of damper brake length overalls, the length of lock medicated cap are 2 millimeters, and width is 1.5 millimeters, and the camber line apogee distance is 0.5 millimeter in the parallel hypothesis line-spacing of the two free-ends lock medicated cap, and the outward flange of lock medicated cap is arcual medicated cap smooth areas in the side.The side view of lock body is asymmetric cuboid, and the nearly lock medicated cap end width of lock body is 1.5 millimeters, and thickness is 1.5 millimeters; Lock point width is 0.7 millimeter, and thickness is 0.7 millimeter, and lock body length overall is 3.5 millimeters; 2 slip ridges are arranged at the back side of lock body; Parallel lock body edge, each slip ridge width is 0.3 millimeter, highly is 0.3 millimeter.The nearly medicated cap end height of each slip ridge and lock medicated cap equate that promptly the nearly medicated cap end of lock body thickness is 1.5 millimeters, comprises the height of slip ridge.There are 4 trianglees friction ditches in the front of lock body, 0.2 millimeter of every friction ditch depth, and damaged form is a right angled triangle at lock body front openings place, 4 friction ditches are arrangement arranged side by side.Distance is 2 millimeters a lock dignity between lock medicated cap and lock body intersection to first friction ditch, and the distance of last friction ditch to lock cusp edge is 0.5 millimeter.Time gating tip, front is the arc of evagination, and the lock tip also is arcual body smooth areas in the side.Tongue side damper brake is formed with lock body two parts by reinforcing is prominent; The lock medicated cap of different with the conventional brake lock is conventional brake lock is positioned at the top of lock body; And the prominent positive top that is positioned at the lock body of the reinforcing of tongue side damper brake promptly is different from the conventional brake water seal perpendicular to the lock body and puts down in the position of lock body.Simultaneously the size of tongue side appliance bracket is different with the used bracket of lip side, and tongue side appliance bracket is less than the used bracket of lip side, so the size of tongue side damper brake little than lip side damper brake, the total length of tongue side damper brake is 3 millimeters; Nearly jaw portion width is 1 millimeter, and the lock body thickness is 1.5 millimeters, and the lock dignity length of the top of lock body to first friction ditch is 1.5 millimeters, and there are 4 leg-of-mutton friction ditches in the front of lock body; Every 0.2 millimeter of ditch depth of friction, friction ditch defect is wide 0.25 millimeter in the front, and 4 friction ditches become side by side to arrange; The distance of last friction ditch to lock tip is 0.5 millimeter, and front, lock tip is the arc of evagination, and the lock tip also is arcual body smooth areas in the side; The lock tip is than top thin for the top is thick for the lock body, and the thickness of lock tip is 0.7 millimeter, the afterburning prominent top that is positioned at lock dignity; Occupy the central authorities of lock dignity, afterburning prominent height is 0.8 millimeter, 0.8 millimeter of afterburning prominent top width; Root is wide 0.5 millimeter, and the top is curved, parallel friction ditch.Afterburning prominent shape is the shape of projection, and afterburning prominent side view type of being dried mushroom shape has 2 slip ridges at the back side of lock body; Parallel lock body both sides of the edge, the width of each slip ridge is 0.3 millimeter, highly is 0.3 millimeter; 1.5 millimeters of the gross thickness of lock body comprise the height of slip ridge.Manufacturing of the conventional brake lock of balance appliance damper brake and tongue side damper brake all is to form with medical stainless steel or medical alloy manufacturing.

Specific embodiments:

In the process of orthodontic, according to corrigent step and operation, when correcting to needs brakings or with the part that tooth is stable to increase anchorage, the braking in the time of can using this damper brake to accomplish the tooth body to move.During use at first with the ligation silk gently the ligation ligation silk of going into bracket or will penetrate bracket loosen; Use fixedly tweezers or other fixed apparatus gripping damper brake; Damper brake is put into the vertical furrow of bracket, advance down to arch wire from nearly gum forward by the lock point at the bottom of the slip ridge is close to vertical furrow, embed the friction ditch to arch wire and get final product; The ligation silk is tightened; Use light power afterburning more afterwards, arch wire is embedded in the friction ditch of relative extreme higher position in the hope of obtaining the highest frictional force, obtain better braking effect simultaneously.The conventional brake lock will add the nearly jaw of lock medicated cap and bracket place when secondary is afterburning is in the same place, and tongue side damper brake then is afterburning prominent adding with bracket to carry out the secondary reinforcing together, when the secondary reinforcing, will not correct the tooth reinforcing of putting together, is prone to bracket and comes off.
