Background technology
Orthodontic treatment is a subdiscipline that degree of specialization is higher of dental field, is mainly to rescue for tooth, jawbone, facial deformity, by oral cavity, inner Fixed Orthodontics appliance recovers patient's normal occlusion function gradually.Bracket is the important component part of orthodontic appliance, is mainly adhered on labial teeth, canine tooth, premolars, and orthodontic treatment is by being arranged in the groove of bracket rescuing arch wire, and the Tooth Movement of guiding dislocation is to desirable position.
Traditional bracket adopts the mode of ligature or the ligation of India rubber circle that arch wire is fixed in groove, but the shortcoming such as this fixed form exists the time-consuming inconvenience of clinical manipulation, frictional force is large, level of comfort is poor.In recent years, the orthodontic treatment that appears as patho-occlusion that locking bracket (self-ligating bracket) is rescued system has been introduced new method.The feature of locking bracket maximum is to substitute conventional junction tied silk (circle) by the self-locking structure of bracket arch wire is carried out to ligation, reduce the frictional force of orthodontic appliance inside, making to rescue efficiency significantly increases, and is a kind of quick, comfortable, safe fixed orthodontic device.At present, locking bracket has low-frictional force, reduces anchorage loss, improves clinical manipulation efficiency, the particular advantages of patient to aspects such as pain reaction are light with respect to traditional bracket, and locking bracket engagement is stable, small and exquisite attractive in appearance, patient wears with comfortable, easy to clean, Chairtime shortens, further consultation interval extends, and rescues that efficiency is high, the course for the treatment of is shorter.Make locking bracket obtain more and more correction doctors' understanding and affirm.
Common locking bracket is slide way type structure (a passive slide) or locker formula structure (a spring clip).Slide way type bracket arranges slip lid in groove both sides, includes arch wire in rear promotion slip lid and forms a closed conduct solid, that arch wire can move freely, claims again passive-type locking bracket (passive self-ligating bracket).The built-in high resiliency locker of locker formula bracket, the elastic pressure of closing rear generation can act on arch wire when needed, provides and continues soft orthodontic force, claims again active locking bracket (active self-ligating bracket).Because the self-locking device multidigit of locking bracket is in bracket metal surface, convenient for instrument or finger tip switch, ligation process is more easy.
But still there are some shortcomings in locking bracket in clinical practice.First be that locking bracket is difficult to locate exactly when bonding, this is due to the double-vane bracket with respect to traditional, there is larger difference in the form of the locking bracket of most kinds and traditional double-vane bracket, locking bracket structure is more complicated and there is no an obvious double-vane, this may cause bonding when locking bracket doctor not portable put, cause the radian of locking bracket base plate and facing not coincide well, be difficult to locate exactly locking bracket.Once locking bracket malposition will be added to the difficulties to later stage intense adjustment, thereby extend the treatment time in intense adjustment stage, made troubles to clinical manipulation.
Next is that locking bracket itself has certain design defect, if affected by some unexpected factor, its slip lid or locker is surprisingly opened, and can lose the control of groove to arch wire, affects therapeutic effect, instead extended treatment time; And due to the complicated structure of locking bracket, some external force (comprising masticatory force) and doctor's maloperation all may cause the damage of locking bracket, thereby cause slip lid or locker to open and to close, when serious, even cause bracket to scrap, increase patient's financial burden, improved treatment cost.
The self-locking device of locking bracket occupies larger space on facing conventionally again, makes the thickness of locking bracket larger, while chewing, may come off, and the poor child of compliance and deep overbite patient use are existed to limitation; Simultaneously because the short and small circle of the bracket wing of locking bracket is blunt, more inconvenient, the easy slippage of maintenance in the time adding ligation adnexa, and in the process of insertion arch wire and taking-up arch wire, locking bracket is compared and is had great uncomfortable property with traditional double-vane bracket, usually causes patient's pain.In addition, in the time using the bending indivedual tooth of Rectangular SS archwires adjustment, arch wire is in place compared with difficult and cannot close slip lid or locker, and these have all limited the use of traditional intense adjustment mode.
