Abstract:
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.
