A mandible displacement adjusting device includes an upper braces and a lower braces, wherein the upper braces and the lower braces have an upper teeth accommodation space and a lower teeth accommodation space, the upper teeth accommodation space and the lower teeth accommodation space are made based on the tooth shape, and fits on the upper and lower dental arches of the human body respectively, and the side walls of the upper braces and lower braces extend out a first positioning part and a second positioning part corresponding to the upper molar area and the lower molar area. When the user wear the upper braces and the lower braces, the first positioning part and the second positioning part would be driven to fit together, and maintain a movable displacement space, so that when the mandible of the human body is moved forward and fixed, it will not cause the mandible of the human body due to tightening, neither cause the discomfort at the condyle, while avoiding the back of the tongue slumping down and blocking the breathing passage.

This invention discloses a personalized maxillary and mandibular combined traction device for patients with skeletal Class II high-angle mandibular retrusion, belonging to the field of orthodontics. The device includes personalized maxillary / mandibular titanium plates, elastic traction components, and brackets. Two elastic traction components are included, one for intruding the maxillary molars and the other for tractioning the mandible forward. The maxillary and mandibular titanium plates are positioned at the center of jawbone resistance and are both 3D-printed integrated personalized designs. The elasticity of the traction components can be selected according to needs. This device simultaneously achieves mandibular advancement and maxillary molar intrusion, efficiently enabling early correction of skeletal Class II high-angle mandibular retrusion patients. It also avoids labial tipping of the lower anterior teeth and mesial tilting of the lower posterior teeth. The titanium plates conform to the jawbone, resulting in minimal intraoperative trauma, precise force control, and significantly improved treatment effectiveness and efficiency.
