摘要:

目的探讨临床常见的正颌手术后,如何很好的维护和调整上下牙列的咬合关系,为临床提供有益的参考。方法选择骨性Ⅰ类双颌前突行根尖下截骨后徙术、Ⅱ类下颌后缩行下颌升支矢状劈开前徙术、Ⅲ类骨性反行下颌升支骨切开后退及合并上颌前徙术各6例患者,共18例患者。正颌手术后依据分类分别行3种不同的牵引模式进行咬合调整。结果18例患者均达到了预期的治疗效果,无1例复发,上下牙列咬合良好。结论依据不同的手术术式和错类型,采用有效的颌间牵引可达到理想的功能咬合关系。

Abstract:

Objective To investigate the orthodontic retention and adjustment of the occlusion after orthognathic surgery. Methods 18 patients were divided into three groups. Group Ⅰ : Cases with skeletal Class Ⅰ bimaxillary protrusion treated by subapical osteotomy; Group Ⅱ : Cases with skeletal Class Ⅱ mandibular retrusion treated by sagittal split mandibular advancement surgery; Group Ⅲ: Cases with skeletal Class Ⅲ treated by Le Fort Ⅰ osteotomy on maxilla and sagittal split osteotomy on mandible. There were 6 patients in each group. Three kinds of orthodontic elastic tractions were used based on different categories of malocclusion and different types of operation. Results 18 patients attained functional occlusion after the orthodontic occlusion adjustment. There was no relapse and malocclusion by surgery. Conclusion Intermaxillary elastics based on different categories of occlusion and different kinds of surgery can improve the occlusion after orthognathic surgery and attatin the functional occlusion.
