Correcting device for assisting protraction of lower jaw and retraction of upper anterior teeth

Abstract

The invention provides a correcting device for assisting protraction of the lower jaw and retraction of the upper anterior teeth and relates to the field of orthodontic clinical instruments. The correcting device comprises a planar guide plate parallel to an occlusal plane, a guide rod, a support and an implant anchorage peg, wherein the planar guide plate is arranged on the central incisor palate side of the upper jaw and engages with lower incisors; the support comprises an arc-shaped body, a first connection rod, a traction post and attaching parts, two ends of the arc-shaped body are respectively connected with the attaching parts, the arc-shaped body is connected with the first connection rod extending near a central direction and the traction post extending near a central occlusion direction; the end, near the central direction, of the first connection rod is connected with the planar guide plate, the guide rod is connected to the occlusion side of the planar guide plate, and the guide rod is abutted to the tongue side of the lower incisors; the implant anchorage peg is arranged on the palate, and a rubber band in a tensional state is arranged between the implant anchorage peg and the traction post.

Description

technical field [0001] The invention relates to the field of orthodontic clinical instruments, in particular to an orthodontic device for assisting mandibular protraction and adduction of upper anterior teeth. Background technique [0002] For the cases of mandibular retrusion and at the peak of growth and development accompanied by crowding of the upper dentition, the treatment process includes adduction and alignment of the upper anterior teeth and forward guidance of the mandible. In traditional treatment, the mandible is performed first. Forward guidance, that is, functional correction, after the functional correction is completed, the second stage of fixed correction will be performed, and the course of treatment will be longer. Contents of the invention [0003] The purpose of the present invention is to provide an orthodontic device that assists in simultaneously realizing mandibular protraction and adduction of the upper anterior teeth. The device can simultaneousl...
