摘　　要：总结97例患者,分析其中16例术后出现咬合关系不良的原因并探讨防治措施。经颌间牵引或固定、颅颌固定或颅颏弹性牵引,14例患者恢复咬合关系,1例再次手术,1例转正畸科会诊。复位不准确、手术操作不当、术后缺少有效的颌间固定、颌间固定不规范是颌骨内固定术后咬合关系不良主要原因,及时解剖复位、手术正确规范、颌间牵引固定及选择性应用颅颌固定或颅颏弹性牵引代替颌间牵引固定是防治颌骨骨折钛板内固定术后咬合关系不良的有效手段。97 cases of jaw bone fractures were treated with rigid internal fixation.16 cases had malocclusion postoperation.The etiology was analyzed and the prevention methods were proposed.Intermaxillary elastic traction or fixation and craniomaxillofacial fixation or craniomentum elastic traction were performed to treat the malocclusion.By this way,14 cases were cured.1 case was operated again to resume the normal occlusion,1 case received occlusal adjustment.Incomplete reduction,incorrect operative performance,deficiency of postoperative intermaxillary fixation and incorrect intermaxillary fixation were the main causes to malocclusion.So anatomic in time reduction,correct operative performance,intermaxillary fixation,application of craniomaxillofacial fixation or craniomentum elastic traction instead of intermaxillary fixation for some special cases are effective methods to correct postoperative malocclusion.
