Intermaxillary fixation (IMF) is conventionally used for treatment of fractures involving maxillomandibular complex both for closed reduction and as an adjuvant to open reduction. To overcome the cumbersome procedure of tooth borne appliances cortical bone screws were introduced in the year of 1989 to achieve IMF which is essentially a bone borne appliance. In our institution we treated 45 cases of mandibular fracture both single and multiple fractures by open reduction over a period of 24 months. IMF screws were used to achieve dental occlusion in all the cases. Various advantages, disadvantages and complications are discussed. In our institutional experience we found that the IMF screws are an ideal device for temporary intermaxillary fixation for the cases having only mandibular fracture.
颌间固定（IMF）传统上用于治疗涉及上颌下颌复合体的骨折，既用于闭合复位，也作为切开复位的辅助手段。为了克服牙支持式矫治器的繁琐操作，1989年引入了皮质骨螺钉来实现颌间固定，其本质上是一种骨支持式矫治器。在我们机构，我们在24个月的时间里通过切开复位治疗了45例下颌骨折，包括单发性和多发性骨折。所有病例均使用颌间固定螺钉来实现牙列咬合。讨论了各种优缺点及并发症。根据我们机构的经验，我们发现颌间固定螺钉对于仅患有下颌骨折的病例来说是一种理想的临时颌间固定装置。
