However, the traditional Twin-block appliance is a movable appliance, which has the following disadvantages: (1) patients can take off and wear it by themselves, and it is difficult to obtain good results for patients with poor cooperation; (2) the retaining part is an arrow clasp, in order to obtain a good retention force, the necessary clinical crown height is required, otherwise poor retention will affect the treatment effect; (3) When wearing the Twin-block, the mandible is in a mandatory position with the help of the appliance. At this time, the muscles will pull backwards, and the force will be directly transmitted to the mandibular anchorage teeth (lower anterior teeth and mandibular bicuspids) through the appliance, resulting in the labially inclined lower anterior teeth being more labial. pour

The invention provides an appliance for mandibular retrusion, and relates to the field of orthodontics. The appliance for mandibular retrusion comprises a maxillary retainer and a mandibular retainer, wherein the maxillary retainer and the mandibular retainer are cast by metals; a maxillary occlusal pad is arranged on the maxillary retainer, and a mandibular occlusal pad is arranged on the mandibular retainer; the maxillary occlusal pad and the mandibular occlusal pad are locked with each other. The appliance for mandibular retrusion can be fixed in the oral cavity of a patient in an adhering manner, has an excellent retaining force, and can be used for effectively correcting mandibular retrusion.
Description
technical field [0001] The invention relates to the field of orthodontics, in particular to an appliance for mandibular retrusion. Background technique [0002] In orthodontic treatment, for patients with mandibular retrusion in the growth and development period, functional correction is required to guide the mandible forward. Among the many functional appliances that guide the mandible forward, Twin-block is favored by patients in orthodontic treatment because it can be worn all day without affecting the patient's eating. However, the traditional Twin-block appliance is a movable appliance, which has the following disadvantages: (1) patients can take off and wear it by themselves, and it is difficult to obtain good results for patients with poor cooperation; (2) the retaining part is an arrow clasp, in order to obtain a good retention force, the necessary clinical crown height is required, otherwise poor retention will affect the treatment effect; (3) When wearing the Twin...
