Description
Technical field
This utility model relates to a kind of self-locking bracket for tooth orthodontic.
Background technology
Correction silk bow fixed orthodontic technology is used to treat that the malocclusion of patient is as uneven in tooth arrangement, torsion, gap etc.Gear division orthodontic bracket is the important component part of mouth cavity orthodontic fixed appliance, orthodontic bracket is fixed on facing, arch wire passes bracket groove and is fixed in supporting slot groove by ligation or self-locking, in orthodontic treatment process, the Orthodontic force of arch wire is delivered to tooth by bracket, makes tooth produce the movement of expection.
At present, locking bracket has low-frictional force relative to conventional brackets, and clinical manipulation is simple, and the time of rescuing is short, patient uses the features such as comfort and convenient, make locking bracket be subject to the favor of more and more orthodontist, at present conventional is the locking bracket with slide lock tabs, but to be used for inserting the chute of slide lock tabs too small due to locking bracket, and slide lock tabs needs to load in chute by tweezers, cause installing not easily, and gravitate easily comes off, and considerably increases installation difficulty.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and facilitates slide lock tabs to install and can not the self-locking bracket for tooth orthodontic of landing.
For achieving the above object, this utility model provides following technical scheme: a kind of self-locking bracket for tooth orthodontic, comprise supporter groove and slide lock tabs, archwire slot is provided with in described supporter groove, the supporter groove of described archwire slot both sides is respectively equipped with chute and locked groove, the described side supporter groove being provided with chute is also provided with the stopper slot preventing slide lock tabs landing, described slide lock tabs is U-shaped, described slide lock tabs is provided with the latch hook coordinated with locked groove for a pair and the spacing preiection coordinated with stopper slot for a pair, described chute dorsad one end port of archwire slot is expand to arrange.
By adopting technique scheme, one end port arranging chute archwire slot dorsad arranges to increase the port size of chute in expanding, and facilitates slide lock tabs to insert; Arrange stopper slot and limit convex to get up to block slide lock tabs and avoid its gravitate to skid off chute simultaneously.
This utility model is set to further: the end face that described slide lock tabs is provided with one end of latch hook is that splayed is arranged.
By adopting technique scheme, one end end face slide lock tabs being inserted chute is arranged to splayed, makes slide lock tabs inserting paragraph in gradually large setting, and minimizing slide lock tabs starts end face size when inserting, and facilitates the insertion of slide lock tabs.
This utility model is set to further: described stopper slot is located on chute, and described stopper slot is communicated with archwire slot, and described stopper slot is greater than the ultimate range of spacing preiection to the end face arranged in splayed along the degree of depth in chute direction.
By adopting technique scheme, above setting avoids slide lock tabs end to block archwire slot.
This utility model is set to further: described spacing preiection is located at the both sides of slide lock tabs and same one end is located at by described spacing preiection and latch hook, and described stopper slot is located on the two side of slideway.
By adopting technique scheme, above setting avoids increasing supporter groove affects comfort.
This utility model is set to further: the upper surface of described chute one end port of archwire slot is dorsad provided with chamfering.
By adopting technique scheme, expanding the openings of sizes of port by arranging chamfering, facilitating the insertion of slide lock tabs.
This utility model is set to further: described chamfer angle is 30 °-60 °.
By adopting technique scheme, being less than 30 ° and establishing port openings less, DeGrain, be greater than lower and excessive easily the rocking of opening of 60 ° of inclination degree of depth that upper surface opening is set and cause inserting.
In sum, this utility model self-locking bracket for tooth orthodontic have structure simple, facilitate slide lock tabs to install and the advantage of slide lock tabs landing can not be caused.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, this utility model self-locking bracket for tooth orthodontic is described further.
As shown in Figure 1, a kind of self-locking bracket for tooth orthodontic, comprise supporter groove 1 and slide lock tabs 3, archwire slot 2 is provided with in described supporter groove 1, the supporter groove 1 of described archwire slot 2 both sides is respectively equipped with chute 12 and locked groove 11, the described side supporter groove 1 being provided with chute 12 is also provided with the stopper slot 13 preventing slide lock tabs 3 landing, described slide lock tabs 3 is in U-shaped, described slide lock tabs 3 is provided with the latch hook 31 coordinated with locked groove 11 for a pair and the spacing preiection 32 coordinated with stopper slot 13 for a pair, described chute 12 dorsad one end port of archwire slot 2 is expand to arrange.One end port arranging chute 12 archwire slot 2 dorsad arranges to increase the port size of chute 12 in expanding, and facilitates slide lock tabs 3 to insert; Stopper slot 13 is set simultaneously and spacing preiection 32 avoids its gravitate to skid off chute 12 to block slide lock tabs 3.
As shown in Figure 2, the end face that described slide lock tabs 3 is provided with one end of latch hook 31 is that splayed is arranged, namely U-shaped slide lock tabs 3 is provided with the both ends of the surface of one end of opening is that splayed is arranged, one end end face slide lock tabs 3 being inserted chute 12 is arranged to splayed, make slide lock tabs 3 inserting paragraph in gradually large setting, minimizing slide lock tabs 3 starts end face size when inserting, and facilitates the insertion of slide lock tabs 3.
As shown in Figure 3, described stopper slot 13 is located on chute 12, and described stopper slot 13 is communicated with archwire slot 2, described stopper slot 13 is greater than the ultimate range of spacing preiection to the end face arranged in splayed along the degree of depth in chute 12 direction, and above setting avoids slide lock tabs 3 end to block archwire slot 2.
Preferably, described spacing preiection 32 is located at the both sides of slide lock tabs 3 and same one end is located at by described spacing preiection 32 and latch hook 31, and described stopper slot 13 is located on the two side of slideway, and above setting avoids increasing supporter groove 1 affects comfort.
As shown in Figure 4, the upper surface of described chute 12 one end port of archwire slot 2 is dorsad provided with chamfering, expanding the openings of sizes of port, facilitating the insertion of slide lock tabs 3 by arranging chamfering; Described chamfer angle is 30 °-60 °, establishes port openings less, DeGrain owing to being less than 30 °, is greater than lower and excessive easily the rocking of opening of 60 ° of inclination degree of depth arranging upper surface opening and causes inserting, therefore arrange between 30 ° to 60 °, preferably 36 °.
The above makes preferred implementation of the present utility model, and under not departing from the prerequisite of this utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
