III CLASS III MALOCCLUSION ORTHODONTIC APPLIANCE

摘要

The present invention relates to a frame (20) of a configuration capable of maxillary arch expansion; A modulator 10 connected to the frame 20 through a first elastic member 41 and configured to be capable of traction of an upper portion of the upper and lower backward movement of the mandible; And a second elastic member (42) connected to the frame (20) to assist anterior traction of the maxilla and backward movement of the mandible, and to separate the upper and lower dentition to eliminate interference due to occlusion And a splinter (30) capable of inducing a correcting force to act smoothly, preventing a dentition of a maxillary posterior tooth to minimize a change in a facial length, and eliminating occlusal interference and stabilizing the jaw joint, It is possible to provide a correcting device capable of correcting Class III malocclusion through lateral retraction of the maxilla and posterior downward movement of the mandible and rearward movement of the mandible.
