摘　　要：目的:探讨自攻牵引钉应用于颌面骨折颌间牵引的并发症及防治对策。方法:总结2007年1月～2009年12月间颌面骨折,应用自攻牵引钉行颌间牵引30例。其中上颌骨骨折5例,下颌骨骨折25例。结果:29例咬合关系恢复至正常,1例咬合关系恢复不良。在222枚螺钉中有39(18%)枚牵引钉在拆除时发现螺钉尾部被口腔黏膜覆盖,有4(2%)枚螺钉断裂。在牵引完成前有7(3%)枚螺钉松动,未发现螺钉两侧的牙根损伤。结论:虽然自攻颌间牵引钉是一种安全,省时的颌间牵引方法,但它本身存在一定的局限性和潜在并发症,临床医生应该意识到这一点,更加安全有效地使用它。Objective：To investigate the prevention and treatment of complications to self-drilling/tapping intermaxillary fixation screws in the management of maxillofacial fracture.Methods：30 patients suffered from maxillofacial fractures and treated with intermaxillary fixation screws from 2007 to 2009 were retrospectively analyzed.There were 5 cases of maxillary fractures and 25cases mandibular fractures.The complications during the treatment were analyzed.Results：Occlusion of 29 cases were restored to normal,but 1 case had malocclusion.During the treatment period,of the total number of screws placed（222）,39（18%）had soft tissue covered the screws,4（2%）had screw fracture;7（3%） became loose but no root fracture.Conclusion：Overall,the self-drilling/tapping screws have been shown to be safe and time-sparing modality to establish maxillomandibular fixation.However,it still has limitation and the surgeon must be aware of ut in order to provide safe and effective treatment.
