Description
Technical field:
This utility model relate to a kind of can the orthodontics self-locking bracket of effective expression torque.
Background technology:
It is attractive in appearance that correct tooth torque is conducive to the foundation of good occlusion, the conduction of power, periodontal health and facing.The situation desirable at the end of rescuing of straight wire appliance should be that built-in torque angle gives full expression to, but torque remains the weakness of straight wire appliance, because the contact surface of torque only relying party's silk and bracket produces twisting resistance, this acting surface is too little relative to the volume of tooth, is difficult to fully work; Simultaneously in orthodontic treatment, the general arch wire size used always is less than slot width, and what be beneficial to arch wire enters the comfortable of groove and patient, and inevitably gap between such bracket groove and arch wire, causes the loss of torque, and then affect the expression of torque.Therefore orthodontist needs bending of arch edgewise suitably to adjust torque direction and the size of upper and lower incisor.But be difficult to the number of degrees accurately controlling arch wire torque clinically, so just easy generation departs from the consequence that normal angle does not have torque force or produces excessive torque power a little.Desirable orthodontic force is persistence, decay low force slowly, the excessive very easy initiation root resorption of torque.
Current existing orthodontic bracket can be divided into traditional ligation type bracket and self-locking type bracket two class from clinical ligature type.And locking bracket substitutes conventional junction tied silk to arch wire by the self-locking structure of bracket to carry out ligation, reduces the frictional force of appliance inside, have the advantages such as anchorage loss is few, clinical manipulation efficiency is high, patient pain's response light.But the locking bracket on market, expensive, in Clinical practice, also there will be closing cap can not open the problem maybe can not closed.Although using the stage of thin arch wire treating tooth can moving teeth fast, but have the following disadvantages: be difficult to when 1, locking bracket is bonding locate exactly, this is because the locking bracket structure of most kind is more complicated and do not have obvious double-vane, cause bond locking bracket time doctor not portable put, be difficult to locate locking bracket exactly.Though 2, frictional force reduces, wayward tooth position, move the inclination of tooth clinically, rotation happens occasionally, sometimes still need to correct and the inclination of prophylaxis of teeth and rotation with ligature ligation arch wire for this reason; 3, the axial rake that particularly labial teeth bracket is prefabricated and angle of torsion will be lost to some extent, sometimes will do necessary compensation deals on arch wire, but arch wire after process is in place more difficult and cannot close slip lid or locker, or moment is afterburning excessive and cause root resorption; 4, the self-locking device of locking bracket occupies larger space usually, makes the thickness of locking bracket comparatively large, may come off when chewing, simultaneously because the short and small circle of the bracket wing of locking bracket is blunt, and more inconvenient, the easy slippage of maintenance when adding ligation adnexa.
Utility model content:
This utility model is in order to make up the deficiencies in the prior art, provide a kind of can the orthodontics self-locking bracket of effective expression torque, its reasonable in design, easy and simple to handle, frictional force is controlled, and arch wire can be come in and gone out arch wire groove easily, accelerates Tooth Movement and also reduces tissue injury; Achieve and effective locking of arch wire is controlled, increase the frictional force of system, thus realize the accurate control to tooth torque, substantially reduce the orthodontist clinical manipulation time, shorten the patient treatment cycle, improve rectifying effect, solve problems of the prior art.
