Description

The stealthy fixed appliance of orthodontics

Art

The present invention relates to a kind of apparatus for correcting (appliance) coming into line, flatten or adjust tooth dislocation deformity for tooth.

Background technology

At present, to misplace uneven orthodontic appliance mainly lip side fixed appliance for straightening of teeth, normally by the metal bracket/cheek pipe (grind one's teeth in sleep upper generally use cheek pipe) being bonded in tooth labial surface, to connect the arch wire of each bracket/cheek pipe and ligature composition, utilize the rebound effect of Resilient Wire to come into line the tooth of dislocation, utilize the high stainless steel silk of thick size hardness as stabilization filament to close extraction of tooth space.This is a kind of universal appliance (general between different patient), bonding agent is utilized directly to be placed on corresponding tooth clinically by orthodontist, the advantages such as have clinical manipulation simple, Tooth Movement controls accurately, the desirable price economy simultaneously of therapeutic effect; Maximum weak point is that appliance is positioned at the buccal labial surface of tooth, easily be exposed to outside, thus affect attractive in appearance, make some have the patient of particular/special requirement (as television anchor to image, performer, government official etc.) and the adult patient high to aesthetic cannot accept.There is the aesthstic bracket (resin or ceramic material) in labial teeth district (exposed region) and aesthstic arch wire afterwards, but cannot realize stealthy completely, still cannot meet for the high patient of aesthetic.

Along with the continuous increase of orthodontics in adults colony, more strong to the requirement of aesthetics treatment, some mouth cavity orthodontics scholar starts clinical research and the practice of stealthy correction, and lingual orthodontics device arises at the historic moment.The composition of initial tongue side fixed appliance and lip side fixed appliance is similar, by lingual bracket/cheek pipe, tongue side arch wire and ligature composition, maximum feature is the lingual surface (inner side) appliance being adhered to tooth, thus appliance is hidden in after tooth, reach extraordinary aesthetic.But lingual orthodontics device does not become main flow in the world, sub-fraction doctor is only had to carry out lingual orthodontics.Tracing it to its cause, it is complicated to mainly contain 1. clinical manipulations, because appliance is positioned at tooth medial surface, no matter lays, and adjustment or dismounting, take time and effort, especially backteeth district, unfavorable to the cervical vertebra health of doctor; 2. lingual orthodontics device is because tooth lingual surface anatomical structure is complicated, can not be other directly bonding at chair, needs first to arrange tooth in skilled worker room, makes and make indirect bonding pallet, and this is also a complicated process; 3. because distinctive biomechanics reason, lingual orthodontics device is for pulling out 4 premolarss, and backteeth is counter to be closed, and angle of elevation case and folding treatment relative difficulty, be not easy Mesial movement lower molar; 4. there is certain difference in the thinking (theory that lip side is rescued) that lingual orthodontics device is traditional with orthodontist on correction times, the person of lacking experience easily carries out the design of mistake, increases the difficulty that case is rescued; 5. price costly.

Summary of the invention

In order to overcome the deficiency of existing lip side appliance and the existence of lingual orthodontics device, the invention provides a kind of new appliance system, this is rescued system and is applicable to treat the relatively large Extraction treatment case of difficulty.This appliance not only has the advantage of lingual orthodontics device invisalign, and can according to the traditional correction times theory of common orthodontist, and clinical manipulation is relatively convenient, realizes the Three dimensions control good to tooth simultaneously and moves.

The technical solution used in the present invention:

In the aesthstic district of labial teeth, the lingual surface of labial teeth places lingual bracket, thus realizes effect stealthy attractive in appearance, overcomes the deficiency that appliance labial teeth district, traditional lip side bracket exposes; In backteeth district (non-aesthetic district), adopt lip side fixed appliance (corresponding modify is carried out to the size of groove), add the control to rear Tooth movement, facilitate the clinical manipulation of orthodontist.So this appliance system is by the lingual bracket of labial teeth, and the labial bracket of premolars, the rustless steel arch wire used when the buccal tube of grinding one's teeth in sleep and the stage that comes into line use high resiliency nitinol and close extraction of tooth space forms.

Be further used as the improvement of technical scheme of the present invention, the lingual bracket that upper and lower labial teeth uses is vertical slot ditch lingual bracket ripe on the market at present, and groove size is 0.018 × 0.028 inch.

Be further used as the improvement of technical scheme of the present invention, the bracket of premolars lip side constructs consistent with traditional lip side straight silk bow supporting groove, but groove size adjusts.Tradition lip side straight silk bow supporting groove groove size only has two kinds, 0.022 × 0.028 inch and 0.018 × 0.028 inch respectively, for cooperation 0.022 × 0.016 inch of stainless steel silk sliding scale closes extraction of tooth space in the technical program, the size of the bracket of described premolars lip side is 0.025 × 0.028 inch;

Be further used as the improvement of technical scheme of the present invention, buccal tube tradition of grinding one's teeth in sleep lip side straight arch wire buccal tube structure is consistent, but lumen size adjusts, and changes 0.025 × 0.028 inch into;

Be further used as the improvement of technical scheme of the present invention, the nitinol size coming into line early application normally 0.012,0.013,0.014 or 0.016 inch, its form is different from the Standard arch wire of lip side fixed appliance, also be different from the mushroom-shaped of lingual orthodontics device, be a kind of distinctive " bullet " form, see accompanying drawing.

The invention has the beneficial effects as follows, had the attractive in appearance of lingual orthodontics device concurrently and controlled accurately with lip side appliance tooth, advantage easy and simple to handle, take into account the impression of patient and the convenient of medical and technical staff's work, reduce medical treatment cost simultaneously.

Detailed description of the invention

In FIG, early stage tooth comes into line the stage, after pulling out frist premolar, at the bonding lingual bracket 1 of labial teeth, premolars labial bracket 2, and buccal tube 3 of grinding one's teeth in sleep, elastomeric " bullet " shape nitinol (4) are put into labial teeth lingual bracket 1, and premolars labial bracket 2 and buccal tube 3 of grinding one's teeth in sleep, fixed by ligature, because tooth is uneven, there is certain deformation.The compensation song of this stage " bullet " shape nitinol second premolars should leave canine tooth lingual bracket 1 one segment distance, is convenient to canine tooth and moves backward, removes crowding anterior teeth.

In fig. 2, elastomeric " bullet " shape nitinol 4 returns to the original form, thus comes into line labial teeth.

In figure 3, after tooth comes into line, utilize " bullet " shape stainless steel silk 6 to guide, close extraction of tooth space.Now the compensation song of " bullet " shape stainless steel silk 6 second premolars should near in canine distal, and free hook is placed at the position of the adjacent song of arch wire.According to clinical molar anchorage design needs, chain circle is suspended to the hook of first molar buccal tube or second molar buccal tube to close extraction of tooth space from free hook.

In the diagram, space closure latter stage, the gap of 0.4mm (stainless steel silk level is to thickness 0.016 inch=0.40mm) between canine tooth and the second premolars, will be remained, and only arch wire need be cut off as labial teeth section and backteeth section, and continue to close residual gap.
