摘要

The purpose of this study was to evaluate the incidence of TMD after treatment with the Mandibular Cervical Headgear (MCH) and fixed appliances in Class III patients. The records of 75 young adult patients (32 female, 43 male) were obtained from two private practices. They comprised three groups: 1. A control group of 25 untreated subjects; 2. 25 Class I patients who had undergone orthodontic non- extraction treatment with fixed appliances; and 3. 25 patients with dentoskeletal Class III disharmonies treated with MCH and fixed appliances.
