Orthodontic device for assisting mandibular protraction and adduction of upper anterior teeth

Abstract

The invention provides an orthodontic device for assisting mandibular protraction and adduction of upper anterior teeth, and relates to the field of orthodontic clinical instruments. The device includes a planar guide plate parallel to the occlusal plane, a guide rod, a bracket, and implant anchorage screws; the planar guide plate is arranged on the palatal side of the maxillary central incisor and occludes with the lower incisor; the support includes an arc-shaped main body, a first connecting rod , a traction post and an attachment part, the two ends of the arc-shaped main body are respectively connected with the attachment part, and the arc-shaped main body is connected with a first connecting rod extending in the mesial direction and a traction post extending in the mesial occlusal direction; the proximal part of the first connecting rod The middle end is connected with the plane guide plate, the occlusal side of the plane guide plate is connected with a guide rod, and the guide rod is against the lingual side of the lower incisor; the implant anchorage screw is set on the upper palate, and the implant anchorage screw and the traction column are set A stretched rubber band. The present invention can carry out functional correction and fixed correction at the same time for the case of mandibular retrusion and the growth and development peak accompanied by crowded upper dentition at the same time, and the treatment time is relatively short.

Description

technical field

[0001] The invention relates to the field of orthodontic clinical instruments, in particular to an orthodontic device for assisting mandibular forward extension and adducting upper anterior teeth. Background technique

[0002] For the case of mandibular retraction and at the peak of growth and development accompanied by crowding of the upper dentition, the treatment process includes the adduction and alignment of the upper anterior teeth and the forward guidance of the mandible. In traditional treatment, the mandible is first performed. Forward guidance means functional correction. After the functional correction is completed, stage II fixed correction is performed, and the course of treatment is longer. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide an orthodontic device that assists the simultaneous realization of mandibular extension and retraction of the upper anterior teeth. The device can simultaneously perform fu...
