Description

The orthodontic bracket system

Technical field

The invention belongs to mouth cavity orthodontic and fixedly rescue technical field, more particularly is the bracket system about just abnormal raw silk rings bow fixed appliance.

Background technology

Just abnormal silk bow fixed orthodontic technology be used for treating patient's grind one's teeth jaw abnormality such as tooth arrangement uneven, reverse, slit etc.Tooth section orthodontic bracket is the important component part of mouth cavity orthodontic fixed appliance, orthodontic bracket is fixed on the facing, arch wire passes the bracket groove and is fixed in the supporting slot groove by ligation or self-locking, the power of rescuing of arch wire is delivered to tooth by bracket in the orthodontic treatment process, makes tooth produce moving of expection.

Orthodontic bracket roughly has following several according to the correcting principle difference of appliance: side's silk bow bracket, Roth straight silk bow supporting groove, MBT slip bracket, Alexander straight silk bow supporting groove, just abnormal Tip-Edge bracket.

Side's silk bow bracket is development fixed appliance parts early.Side's silk bow fixed appliance is still most widely used in the world general at present, influence the most far-reaching a kind of dynamical orthotic device, although in the evolution of this technology, some schools have appearred, fragment bow technology as Burstone, the biological progressive technology of Ricketts, Alexander raw silk rings begg appliance technology, MBT raw silk rings begg appliance technology and MEAW technology etc., but ultimate principle all is similar with rescuing thought, all be to contact with the tight of rectangle groove, make tooth precisely controlled and mobile on three dimensions, thereby allow strong smelting effect reach to the greatest extent perfectly condition by side's silk bow.But when application side's silk bow bracket, the doctor need bend and adjust arch wire for a long time on the chair side when operation, and working strength is big, and efficient is low, and these methods that bend and adjust arch wire are difficult for grasping for the abecedarian.

Roth straight silk bow supporting groove and MBT slip bracket etc. have been preset on the bracket because of the ideal position angle that the tooth expection will be reached, so, do not need basically arch wire is bent, improved clinical position efficient, be subjected to increasing just abnormal doctor's welcome.

The orthodontic bracket basis fixedly method difference of arch wire can be divided into three kinds: common bracket, self-locking bracket and tubulose bracket.

Common bracket is the bracket that has wings of being invented in early days and using.It is to adopt active ligation, exactly by with the ligation of the bracket wing utility arch and bracket closely being strapped in steel wire or elastic tape, can realize well the control of tooth on three dimensions, but this fixed form makes the frictional force between utility arch and the bracket groove bigger, thereby influences moving of tooth and make the orthodontic treatment time lengthening.Another shortcoming of common bracket is that steel ligature usually causes damage to the oral mucosa that is contacted.

The self-locking bracket has overcome the shortcoming of common bracket, it is that the slide plate that has by bracket self or cover plate that can folding are fixed on utility arch in the supporting slot groove, because utility arch is strong at supporting slot groove door sliding, therefore reduced the frictional force between arch wire and the supporting slot groove, thereby the tooth translational speed is accelerated, shortened the just abnormal clinical treatment time.In addition, use the self-locking bracket and rectify smelting, because system's internal friction seldom, what rescue that process adopts is the slight force that continues whole, and tooth can better be realized whole moving, and just abnormal doctor can prolong patient's further consultation interval.Using common bracket just abnormal further consultation blanking time is about 4 weeks, and the further consultation of using the self-locking bracket to rectify to live can extend to 8-10 week at interval.But, the self-locking bracket also has the some shortcomings part, first, the self-locking bracket is made up of bracket body and slide plate or cover plate two parts textural, because the volume of bracket is less, makes its manufacturing process complexity, cost is higher, its price is several times of common bracket normally, can not be accepted by Most patients.Secondly, in the orthodontic treatment process, the slide plate of self-locking bracket or cover plate need folding repeatedly and cause damage easily, at this moment need to change bracket and bring very big inconvenience for just abnormal doctor.

The tubulose bracket paste grind one's teeth in sleep on the time be also referred to as the buccal tube of grinding one's teeth in sleep, also there is the doctor that the tubulose bracket is put into labial teeth in the recent period and does orthodontic, but have no idea to utilize the square arch wire tooth to be carried out three-dimensional control location owing to its groove is cylindrical in the treatment later stage, so, this tubulose bracket can only be done simply tooth and come into line, for comparatively complicated case history, when needs paste each tooth with bracket, laying of utility arch will be very difficult, and this makes this tubulose bracket seldom be used.

At present, the patient is more and more higher to the requirement aspect the beauty treatment in the orthodontic treatment process.Metal bracket is because of its good intensity and be easy to shape and be widely used, but that its color and luster is an impediment to is attractive in appearance, and this just causes bending the appearance of creamy white brackets such as porcelain and plastics.Though the creamy white bracket has satisfied patient's beauty treatment requirement, will make the self-locking bracket because of its physical characteristic just needs very high technology manufacturing, and consequently price is very expensive, embarrasses popular patient to accept.

This shows, above-mentioned each bracket yarn system respectively has its pluses and minuses and uses limitation, so just abnormal doctor and patient expect to have a kind of appearance of new orthodontic bracket system, this system will satisfy like this some demands: manufacturing process is simple, and price is suitable and can satisfy patient's beauty treatment demand; Frictional force is little between utility arch and supporting slot groove, the utility height; The doctor is easy to use, and it is comfortable that the patient feels.
