Description
Technical field
The invention belongs to field of medical auxiliary equipment, are related to underuption, and in particular to a kind of face of underuption
Posture tractor.
Background technology
Underuption is common dentognathic deformity, can betide any tooth position of full denture, these dentognathic deformities can be serious
Face appearance and masticatory function are influenced, often influences to face tooth health.Early treatment can be carried out to impacted tooth, this is for impacted tooth and neighbour
The prognosis of tooth is extremely important.More early beginning rectifying effect is better, starts to rescue adjustable tooth location of root in early days, make impacted tooth and
Adjacent teeth disengages, it can be promoted to play last root of the tooth growth potential rudimentary root of the tooth, root of the tooth is made to continue to develop.It is no
Then, necessarily there is short and curved even root in budding root of the tooth to absorb, final impacted tooth or adjacent teeth have to pull out.
The difficult point of underuption traction：1. drawing force direction reduction impacted tooth by control when drawing impaction Tooth movement to lead
2. prevent tractive force is too small from impaction tooth being caused not move or draw by controlling tractive force size the injury for facing tooth when drawing
Power is excessive to cause the appliance bonding of impaction odontoseisis 3. impacted tooth difficult, since surgical operation opens a window exposure impacted tooth crown face
When, the blood saliva of surrounding is easy pollution, causes appliance to be very easy to fall off, once appliance falls off, needs patient again
Row surgical operation windowing exposure impaction corona row is bonded again, if appliance is fallen off repeatedly so that drawing failure.
Orthodontist often rescues impacted tooth by conventional surgical operation windowing and elastic traction at present, and impacted tooth is led
Guiding to entopic method mainly has fixed appliance method and removable appliance method, but has some disadvantages：
First, it is drawn using dental arch and arch wire as anchorage：It can simultaneously be applied during orthodontic, foreign body sensation is low, but
The shortcoming of the method：1. the method is vulnerable to the blocking of adjacent teeth root when drawing underuption, often there is adjacent teeth root and absorbed；②
There is dental arch deformation as anchorage in dental arch when rescuing, and part is small to open tooth conjunction；3. the appliance bonding of impacted tooth is difficult.
Second, removable appliance method：The method be using removable appliance lip, cheek side attachment as anchorage, can be according to requiring
Force direction is rescued in adjustment, and impacted tooth distraction procedure can be made more controllable, reduces the absorption of adjacent teeth root.But there is also many for the method not
Foot place：1. the direction and the size that adjust reinforcing are limited；2. can not simultaneously be used with fixed appliance, the time is rescued in extension；③
It can not simultaneously be used with Anterior crossbite appliance, may miss and most preferably rescue the time.4. the appliance bonding of impacted tooth is difficult
