不同年龄组骨性Ⅲ类错FR-Ⅲ功能调节器临床疗效分析

Skeletal class Ⅲ malocclusion in two age group patients with FR-Ⅲ functional regulator efficacy analysis

目的:探讨FR-Ⅲ型功能调节器对不同年龄段骨性Ⅲ类错患者的矫治效果。方法:28例上颌发育不足为主的骨性Ⅲ类错患者,分成小年龄组(5～8岁)和大年龄组(9～12岁),采用FR-Ⅲ型功能调节器治疗,治疗前后拍摄头颅定位侧位片并用Winceph8.0X线头影测量软件进行分析。结果:FR-Ⅲ型功能调节器对两组患者均产生良好的矫治效果,上颌骨前移,下颌骨向后下旋转,反解除,侧貌明显改善。小年龄组患者在更短的治疗时间内获得更多的骨骼改变而牙代偿改变较小。结论:FR-Ⅲ型功能调节器对生长高峰期患者有效,在生长发育早期使用效果更好。

Objective：To investigate the function of FR-Ⅲ-type regulator of bone of different ages Ⅲ malocclusion patients.Method：28 cases of maxillary hypoplasia mainly Class Ⅲ skeletal malocclusion patients,divided into small age group（5～8 years）and older group（9～12 years）,the use of FR-Ⅲ functional regulator therapy,treatment lateral head position before and after the film shooting and cephalometry Winceph 8.0X measurement and analysis software.The Result：FRⅢ functional regulator of the two groups of patients are a good treatment effect of maxillary advancement,mandibular backward rotation of anti-Hop lifted profile improved significantly.Younger patients treated in a shorter period of time for more changes in the bone changes in compensatory smaller teeth.Conclusion：FR-Ⅲ-type function of growth regulator effective in patients with the peak period in the early growth and development of better.
