Description
Technical field
The utility model relates to a kind of displacement tooth spring leaf, rotated teeth spring leaf and rotated teeth appliances.
Background technique
Dental appliance is that clinic is widely used because of the effect of its Three dimensions control Tooth movement, the basic principle is that by viscous
The bracket on tooth is connect, sees Fig. 1, the Orthodontic forces such as tractive force of the elastic force of steel wire, elastic tape are transmitted to tooth, tooth is moved
Move ideal position.The dislocation of tooth has near and far, lip (cheek) tongue to, torsion, a high position, low level, inclination etc., therefore corrects tooth
The tooth move mode that tooth needs has near and far, lip (cheek) tongue to, torsion, vertically to, control root torque etc..The non-self-lock-ing of commercialization
Bracket method meets the needs of clinical orthodontic, needs that draw hook is cooperated to use, by draw hook putting forth effort as elastic force rubber band etc.
Point.At present there are mainly two types of the structures of draw hook, one is using ligature to be made by doctor, under this mode, ligature
Silk frangibility, time-consuming, and easily loosens, rotates, shifts, falls off when in use, causes traction effect not good enough.Another kind is bracket
Included draw hook under this mode, since draw hook is completely fixed on bracket, is unable to satisfy and is adjusted for specific demand
It is whole, and since included draw hook setting protrudes, in outside when setting, influence beauty.
Correction NITI Ω arch wire is by bonding appliance on facing, and arch wire is placed in groove, and Orthodontic force is by rescuing
Device is transmitted on tooth, is made to grow the tooth in alveolar bone and is moved to normal position.In orthodontic treatment, moving in rotation is tooth
It is most complicated in moving process, most difficult.Traditional non-self-lock-ing appliance is in the malocclusion therapeutic process for correcting torsion tooth, often
Tongue button often is bonded in torsion tooth tongue side, forms a pair of of couple in lip side and tongue side, torsiversion malposition tooth is gradually corrected in Z-shaped traction.
It is had the following problems under this mode:
One, bracket clinically is bonded in torsion tooth cheek-tongue side, is drawn round about with rubber band, tongue side bonds bracket first
Foreign body sensation is more strong, stimulates tongue side mucous membrane, reduces comfort level；Elastic chain ring strength decaying is very fast, and patient's further consultation is frequent, such as
If patient fails further consultation on time, affect the treatment；Rubber band is impregnated by saliva for a long time, and by various abrasions when chewing, strength is uneven.
Two, when torsion torsion of teeth angle is bigger than normal, with adjacent teeth at a distance of relatively closely, clinic bonding bracket or tongue button difficulty are larger, behaviour
Make difficulty increasing.
Three, when reversing tooth and being repaired to normal position, the later period often needs traction therapeutic to adjust occluding relation, due to general
Draw hook is not carried on logical non-self-lock-ing bracket, clinically often completes to lead by using the homemade round deduction cap draw hook of ligature
Draw treatment.A possibility that shifting, loosening, rotate, falling off can occur in use in this homemade round deduction cap draw hook,
Cause traction effect not good enough, influences treatment process.In addition, draw hook placement location because operator be accustomed to and experience it is variant, shadow
Ring traction effect.
The above problem is should to pay attention to and solve the problems, such as during orthodontic.
Utility model content
The purpose of the utility model is to provide a kind of dedicated displacement tooth spring leafs of non-self-lock-ing bracket, solve existing skill
Draw hook is made using ligature present in art, ligature frangibility, time-consuming, and easily loosen, rotate when in use,
It shifts, fall off, cause traction effect not good enough；Using at high cost existing for included draw hook, draw hook is completely fixed on bracket,
It is unable to satisfy aiming at the problem that specific demand is adjusted.
The purpose of this utility model is also to provide a kind of dedicated rotated teeth spring leaf of non-self-lock-ing bracket and rotated teeth is rectified
Device is controlled, solution is existing in the prior art to bond bracket in torsion tooth cheek-tongue side, is drawn round about with rubber band, first tongue side
It is more strong to bond bracket foreign body sensation, stimulates tongue side mucous membrane, reduces comfort level；Elastic chain ring strength decaying is very fast, Huan Zhefu
It examines frequently, if patient fails further consultation on time, affects the treatment；Rubber band is impregnated by saliva for a long time, by various abrasions when chewing,
The problems such as strength is uneven.
