| 摘 要： | 目的 探讨上颌快速扩弓对成人牙龈退缩的影响。方法 测量成人上颌快速扩弓组 (RME组 )和非上颌快速扩弓矫治病例组 (对照组 ,C组 )治疗前后牙牙合石膏模型临床牙冠高度的变化。结果 矫治前后第一磨牙、第二前磨牙、第一前磨牙临床牙冠高度的差值与C组矫治前后同名牙临床牙冠高度的差值比较 ,男性RME组无统计学意义 ,女性RME组第二前磨牙无统计学意义 ,第一磨牙和第一前磨牙的差值有统计学意义。结论 成人上颌快速扩弓不会加速和 (或 )导致成人牙龈退缩。

| Abstract: | Objective To investigate the gingival recession of adults after rapid maxillary expansion. Methods Clinical crown heights of premolars and first molars were measured on the plaster model for both the group of adult rapid maxillary expansion (RME) and the group of non-rapid maxillary expansion (C) before and after treatment. Results In male group, comparison between the RME and the C groups generally was not significantly different. In female group, there was no difference for the second premolar, but there was significant difference for the first premolars and first molars. Conclusion RME did not promote or induce an increase in this naturally occurring gingival recession. |
