摘要： 目的:介绍并评价利用后方牙合诱导治疗骨性II类下颌后缩畸形的方法。方法:16例骨性II类下颌后缩畸形患者,年龄16~30岁。治疗前SNA基本正常,SNB≤75°,ANB≥5°,磨牙关系为双侧远中关系。常规排齐整平及适当扩弓后利用多曲唇弓暂时消除磨牙区咬牙合干扰,并通过升高下颌双尖牙,远中倾斜上颌后牙段,使双尖牙区形成暂时的早接触,进而建立双尖牙区的后方牙合诱导,利用后方牙合诱导引导后缩的下颌骨适当向前建立咬牙合,并纠正磨牙的远中关系。 结果:所有患者磨牙关系均调整到中性,侧貌改善明显,SNB平均增大1.58°,下颌前牙略有唇倾,但无统计学意义。结论:利用后方牙合诱导可适度纠正骨性II类下颌后缩畸形。

Abstract: Objective: To introduce and evaluate the method to correct skeletal class II malocclusion with mandible retrusion by using retrusive guidance. Methods: Sixteen patients with skeletal class II mandibular retrusion, aged from 16 to 30 were treated. Before treatment, SNA was normal, SNB≤75°, ANB≥5°. Molar relationship was class II. The treatment began with aligning and leveling the upper and lower dental arch, then upper arch was expanded when necessary. Multiloop edgewise arch wire (MEAW) was used to eliminate molar interference, then to extrude lower premolars and tip back upper posterior teeth, so premature contact could be obtained and premolar retrusive guidance was established to guide the mandible forward. Results: Molar relationship of class II was improved to class I. SNB increased by 1.580 on average. Lower anterior teeth flared slightly but not significantly. Conclusion: To some extent, the retrusive guidance can be used to correct skeletal class II malocclusion with mandible retrusion.
