【摘要】 目的:探讨正畸治疗失误病例的特征及失误原因。方法:根据37例经各类口腔医疗机构治疗结束、中断或正在进行的正畸病例的原始资料及来诊时采集的资料,将这些失误病例的原始畸形和现畸形分别分类,分析总结这些病例的特征及失误原因。结果:37例治疗失误患者中,Ⅲ类错(牙合)最多,共26例,占70.27％,而尤以替牙(牙合)期的问题最为严重,畸形从单纯的前牙反(牙合)发展为同时伴有牙列颌骨的偏斜、开(牙合)等严重问题。出现问题的原因主要为诊断及治疗方案、阻断性矫治、矫治器制作、颌间牵引和口外弓使用及治疗程序等方面的失误。结论:失误病例种类及原因多种多样,但以Ⅲ类错(牙合)问题最多且最严重,特别是替牙(牙合)期,这提示我们要慎重对待Ⅲ类错(牙合)的治疗。更多还原

【Abstract】 PURPOSE: To evaluate the characteristics and reasons for mistakes in some orthodontic cases. METHODS: 37 cases after or during treatment in other hospitals with mis-treatment were chosen, their original records as well as the records when they came to our hospital were collected, their original and present malocclusions were classified and the characteristics and reason of mistakes were analysed. RESULTS:Among the 37 cases, 26 cases had class-Ⅲ malocclusion which account for 70.27% of the group, especially for the malocclusions began in mixed dentition and the problems developed from anterior dental crossbite to severe skeletal crossbite with dentofacial asymmetry and openbite. The main reasons lie in the mistakes of diagnosis and treatment planning、preventive treatment,appliance fabrication,use of extraoral arch and elastics,treatment processes, et al. CONCLUSIONS: There are various characteristics and reasons of treatment mistakes, but the problems lie mainly in class-Ⅲ malocclusion especially during mixed dentition which indicates that we should pay more attention to the treatment of class-Ⅲ malocclusion.更多还原
