Through setting up traction hook 9 and external tractive subassembly, when needs carry out antedisplacement to the upper jaw, can realize the antedisplacement tractive to the upper jaw, realize better the effect of correcting.
The specific process of using the muscle function adjusting orthodontic appliance for the III-type malocclusion deformity comprises the steps of ordering a patient to sit on a dental chair, relaxing the whole body, enabling the back and the head to lean against the chair back, taking down the normal middle jaw position wax biting of the jaw according to a conventional method, and taking up an upper jaw tooth model and a lower jaw tooth model. And transferring the model to a occlusal frame according to the biting wax, and manufacturing the appliance. After the preparation of the muscle function adjusting orthodontic appliance for the class III malocclusion deformity is completed, the lower jaw teeth of the patient are worn and debugged. The patient can realize the lifting of the tongue body by wearing the correction device, and the problem that the lower jaw generates forward thrust because the tongue body descends is effectively prevented. When the upper jaw of the patient is narrow, the upper jaw correcting component is used for correcting.
This kind of a muscular function control orthodontic appliance for class III malocclusion deformity through carrying out joint control to tongue muscle and masticatory muscle function, can carry out physiological improvement to the malocclusion deformity in the short time. The function of the tongue muscle and the masticatory muscle are adjusted by additionally arranging the tongue spine 3 on the lower anterior lingual side and adopting the muscle relaxing jaw pad 1. When maxillary arch stenosis exists, correction is further realized by matching the maxillary correcting component. When the upper jaw needs to be dragged forwards in a matched manner, the upper jaw can be further additionally provided with a dragging hook 9 to be matched with an external dragging component, so that the upper jaw is dragged.
This a just abnormal ware of rescuring of muscle function regulation for III class malocclusion deformity, can solve and present to III class malocclusion deformity, mostly use external force to carry out jaw traction or tooth removal, there is not the problem that the joint muscle function adjusting device that an effectual tongue muscle position training and masticatory muscle relax reaches physiological correction, and muscle function is not the important factor of relapse after the treatment, therefore the embodiment the device carries out effective joint regulation to tongue muscle and masticatory muscle function, can improve the long-term stability of treatment, effectively avoid the problem of relapse after the treatment.
This kind of a muscle function regulation just abnormal correction ware for III class malocclusion deformity locates the lower jaw through muscle loose jaw pad 1, uses the space of oral cavity lower part, and this design can lift the tongue body passively on the ground, and it is too big when avoiding muscle loose jaw pad 1 to adhere to, hinders to lift on the tongue body, leads to the problem that can not change the position of the tongue body well. The muscle function adjusting orthodontic appliance for the III-class malocclusion deformity can adjust the occlusal position of a III-class patient by adjusting the functions of the obturator muscle and the tongue muscle, is used for performing programming on the muscle before fixed correction to return the condyloid process to the temporomandibular joint positive middle position and improve the III-class occlusion relation; thereby achieving the purpose of reducing later-stage fixation and correction, improving the function of bad muscles and increasing the long-term stability of treatment.
