Treatment of maxillary retrusion using maxillary protraction combined with rapid palatal expansion in different age 扩弓联合前牵引治疗不同年龄段的上颌发育不足
Results: Both complete unilateral cleft lip and palate groups had almost the same significant degree of maxillary retrusion compared with the normal control group. 结果:唇腭裂均修复组与仅唇裂修复组具有基本相似的上颌骨生长抑制。
Conclusion: After cleft lip repair maxillary retrusion will happen. 结论:唇裂修复术后会出现上颌后缩的生长发育畸形。
Mangement of the maxillary retrusion includes orthognathous treatment and distraction osteogenesis. Distraction osteogenesis has become the ideal method because of the advantages such as extensive application, less damage, exact effect and lower recurrence rate. 上颌后缩的治疗包括传统正颌治疗和牵引成骨治疗,由于牵引成骨具有应用范围广、创伤小、效果确切、复发少的优点,现成为治疗上颌后缩的理想方法。
