Description

TECHNICAL FIELD

[0001] The utility model relates to molar distal movement device technical field, specifically point to a kind of molar moving towards distal end and push the orthodontic device. BACKGROUND

[0002] Dental defect refers to the loss of part of teeth in dentition, and the treatment can be performed by using removable partial denture, fixed denture (fixed bridge), covering denture, implant denture and other treatment methods. However, in clinical work, individual posterior tooth loss is often seen, and in addition to small range of atrophy of the alveolar ridge in the local tooth defect, the remaining teeth often tilt to the defect side, so the molar needs to be distally moved before treatment.

[0003] The existing molar distal movement treatment requires the patient to wear a full mouth fixed appliance, and after the full dentition is fully aligned and leveled, the T-shaped curved arch wire is inserted into the slot, and the remaining teeth are used as a whole support to apply force to the tilted tooth. At the same time, the molar is pushed distally by the elastic element arranged between the tilted tooth and the remaining tooth adjacent to the missing tooth. The above structure cannot guarantee the stability of the molar during distal movement.
