Intermaxillary fixation (IMF) screws were first introduced to achieve IMF as a kind of bone borne appliance for jaw fractures in 1989. Because this method can overcome many disadvantages associated with tooth borne appliance, IMF screws have been popularly used for jaw fractures since then. From March 2011 to February 2014, we treated 168 cases with single or multiple jaw fractures by open reduction and a total of 705 IMF screws were intraoperatively applied in all the cases to achieve IMF and maintain dental occlusion as an adjuvant to open reduction. The numbers, implantation sites and complications of IMF screws were retrospectively analyzed. In our experience, we found that IMF screws were important to assist open reduction of jaw fractures but their roles should be objectively assessed and the reliability of open reduction and internal rigid fixation must be emphasized. Much attention should be paid when implanting.
颌间固定（IMF）螺钉于1989年首次被引入，作为一种用于颌骨骨折的骨支持器械来实现颌间固定。由于这种方法可以克服与牙支持器械相关的许多缺点，自那时起，IMF螺钉就被广泛用于颌骨骨折的治疗。2011年3月至2014年2月，我们对168例单颌或多颌骨折患者进行了切开复位治疗，术中共应用了705枚IMF螺钉以实现颌间固定并维持牙列咬合，作为切开复位的辅助手段。对IMF螺钉的数量、植入部位及并发症进行了回顾性分析。根据我们的经验，我们发现IMF螺钉对于辅助颌骨骨折的切开复位很重要，但应客观评估其作用，并且必须强调切开复位和坚固内固定的可靠性。植入时应予以高度重视。
