Description
Technical field
This utility model relates to a kind of orthodontic bracket, particularly a kind of passive type self-ligating orthodontic bracket.
Background technology
Along with orthodontic is more and more general, the requirement of people to orthodontic bracket and correction process is also more and more higher.Used straight silk bow supporting groove is generally first be connected with the arch wire designed, then straight silk bow supporting groove and arch wire fixed with ligature or ligature loop.Because these operations all need to carry out in patient oral cavity, and operate cumbersome, the set time is longer, patient is more painful in correction process.Meanwhile, owing to using ligature or ligature loop to fix straight silk bow supporting groove and arch wire, need often to carry out further consultation.In addition, the correction cycle of existing straight silk bow supporting groove is general longer.In order to solve the problem, locking bracket is used to fix straight silk bow supporting groove and arch wire at present.But current locking bracket ubiquity partially thick problem, affects comfort level when patient wears.Therefore, existing orthodontic bracket also exists the problem that operation comparatively bothers, the set time is longer, correction cycle is longer, further consultation interval is longer, patient is more painful and comfortable wearing degree is undesirable.
Utility model content
The purpose of this utility model is, provides a kind of passive type self-ligating orthodontic bracket.This utility model, when not increasing bracket thickness, not only has simple to operate and that the set time is shorter advantage, can also extend further consultation interval, shorten correction cycle, alleviate patient suffering, improve comfortable wearing degree.
The technical solution of the utility model: passive type self-ligating orthodontic bracket, comprises supporter groove, is provided with mesh floor bottom supporter groove; Supporter groove is provided with the groove that runs through supporter groove and the T-shaped chute perpendicular to groove, and the intersection of groove and T-shaped chute is provided with draw-in groove; Be provided with through hole below T-shaped chute, T-shaped chute head both sides are equipped with square through hole; T-shaped chute is connected with T-shaped locking plate, and T-shaped locking plate comprises upper and lower two-layer; The head both sides of T-shaped locking plate lower floor are equipped with elasticity card horizontally outward, are provided with movable space between the elasticity card of both sides; The afterbody of described T-shaped locking plate lower floor is by being welded to connect T-shaped locking plate upper strata, and elastic card body can be freely movable to both sides.
In aforesaid passive type self-ligating orthodontic bracket, described movable space is positioned at immediately below T-shaped locking plate upper strata, and is covered in by T-shaped locking plate upper strata completely.
In aforesaid passive type self-ligating orthodontic bracket, described supporter groove and T-shaped locking plate are non-corrosive material, and on supporter groove and T-shaped locking plate, all seamed edges or corner angle are arc-shaped edges or fillet.
Compared with prior art, this utility model improves orthodontic bracket structure.This utility model have employed the push-pull structure of T-shaped locking plate and T-shaped chute, makes supporter groove have passive type auto-lock function, avoids the fixing operation using ligature or ligature loop; Thus simplify operation, shorten the fixed cycle, extend further consultation interval, make orthodontist operate while alleviating the misery of patient handy.Meanwhile, the thickness of supporter groove can not also be increased.And this has through hole to this utility model below T-shaped chute, reduce the contact area of T-shaped locking plate lower surface and supporter groove, thus improve the sliding speed between arch wire and groove, make that torque is faster, correction cycle is shorter.In addition, on supporter groove and T-shaped locking plate, all seamed edges or corner angle are arc-shaped edges or fillet, are to wear more comfortable, further mitigate the misery of patient.Therefore, this utility model, when not increasing bracket thickness, not only has simple to operate and that the set time is shorter advantage, can also extend further consultation interval, shorten correction cycle, alleviate patient suffering, improve comfortable wearing degree.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described, but not as the foundation limited this utility model.
Embodiment.Passive type self-ligating orthodontic bracket, forms as shown in figures 1 to 6, comprises supporter groove 1, be provided with mesh floor 2 bottom supporter groove 1; Supporter groove 1 is provided with the groove 3 that runs through supporter groove 1 and the T-shaped chute 4 perpendicular to groove 3, and groove 3 is provided with draw-in groove 5 with the intersection of T-shaped chute 4; Be provided with through hole 6 below T-shaped chute 4, T-shaped chute 4 head both sides are equipped with square through hole 7; T-shaped chute 4 is connected with T-shaped locking plate 8, and T-shaped locking plate 8 comprises upper and lower two-layer; The head both sides of T-shaped locking plate 8 lower floor are equipped with elasticity card 9 horizontally outward, are provided with movable space 10 between the elasticity card 9 of both sides; The afterbody of described T-shaped locking plate 8 lower floor is by being welded to connect T-shaped locking plate 8 upper strata, and elasticity card 9 can be freely movable to both sides.
Described movable space 10 is positioned at immediately below T-shaped locking plate 8 upper strata, and is covered in by the upper strata of T-shaped locking plate 8 completely; Described supporter groove 1 and T-shaped locking plate 8 are non-corrosive material, and on supporter groove 1 and T-shaped locking plate 8, all seamed edges or corner angle are arc-shaped edges or fillet.
This utility model connects supporter groove 1 and T-shaped locking plate 8 by T-shaped chute 4, and T-shaped locking plate 8 can slide along the relative supporter groove 1 of T-shaped chute 4.When carrying out self-locking, inwardly promote T-shaped locking plate 8 to promoting; Now, T-shaped locking plate 8 is across groove 3 and the arch wire pinned in groove 3; The elasticity card 9 of T-shaped locking plate 8 lower floor snaps in square through hole 7, fixing T-shaped locking plate 8.When removing self-locking, pull out T-shaped locking plate 8 to exposing groove 3; Now the elasticity card 9 of T-shaped locking plate 8 lower floor snaps in draw-in groove 5, prevents T-shaped locking plate 8 from coming off from supporter groove 1, facilitates carry out self-locking next time.Above-mentioned plug-type design, when not increasing supporter groove thickness, achieves passive type self-locking.Be provided with movable space 10 between the elasticity card 9 of T-shaped locking plate 8 lower floor, facilitate the activity of elasticity card 9, also can slide in T-shaped chute while making elasticity card 9 can snap in draw-in groove 5 and square through hole 7.The upper strata of T-shaped locking plate 8 can cover in the movable space 10 in T-shaped locking plate 8 lower floor completely, prevents other objects in cavity from snapping in movable space 10, ensures that elasticity card 9 can be freely movable.
During installation, pull out T-shaped locking plate 8, the elasticity card 9 now on T-shaped locking plate 8 snaps in draw-in groove 5, exposes groove 3 completely.Then the groove 3 on supporter groove 1 is stuck in the position that arch wire sets, then inwardly will promotes T-shaped locking plate 8 to promoting.Now, the elasticity card 9 on T-shaped locking plate 8 snaps in square through hole 7 due to the effect of elastic force, and T-shaped locking plate 8 is fixed on supporter groove 1.Meanwhile, because T-shaped locking plate 8 is positioned at directly over groove 3, arch wire is stuck in groove 3 by T-shaped locking plate 8, plays the effect of passive type self-locking.
During dismounting, use specific purpose tool to pull out T-shaped locking plate 8, the elasticity card 9 on T-shaped locking plate 8 is stressed movable in the movable space 10 of centre, and elasticity card 9 snaps in draw-in groove 5 after departing from from square through hole 7, expose groove 3, now just can easily supporter groove 1 be taken off from arch wire.
