A patient with skeletal Class III malocclusion was treated in 2 phases during the early permanent dentition. In phase 1, maxillary protraction was combined with rapid palatal expansion; in phase 2, fixed appliances were placed. The results were good posttreatment, and, 1 year later, a favorable growth tendency could be observed. This report shows that treatment for a patient with skeletal Class III malocclusion can be started in the early permanent dentition, with very good final results.
一名恒牙早期的骨性Ⅲ类错牙合患者接受了两期治疗。第一期，上颌前牵引联合快速腭开展；第二期，佩戴固定矫治器。治疗后效果良好，1年后观察到有良好的生长趋势。本报告表明，骨性Ⅲ类错牙合患者的治疗可在恒牙早期开始，最终效果非常好。
