目的：评估下颌骨后移手术与不颌间固定（IMF）screen.Patients和方法的骨骼稳定性：受试者是40例下颌骨无颌症患者。受试者接受了升支矢状劈开截骨术和钛板固定，并分为2组，I组使用和I组不使用IMF螺钉。术前、术后即刻、术后1个月、3个月和6个月分别进行头颅侧位片检查。结果：在重复测量方差分析的两组间的时间过程变化的比较中，咬合平面（受试者之间，F = 2.517; df = 4; P = 0.0437）和凸度（受试者之间，F = 4.048; df = 4; P = 0.0038）存在显著差异。然而，在其他measurement.Conclusion：这项研究表明，在大多数测量，有没有IMF螺钉的时间过程中的骨骼变化的2组之间没有显着差异。然而，使用IMF螺钉作为IMF的刚性锚钉有助于正颌手术。(c)2007年美国口腔颌面外科医师协会。
Purpose: To assess skeletal stability after mandibular setback surgery with and without an intermaxillary fixation (IMF) screw.Patients and Methods: The subjects were 40 patients with mandibular prognathism. The subjects underwent sagittal split ramus osteotomy with titanium plate fixation and were divided into 2 groups, I with and I without an IMF screw. A lateral cephalogram was done preoperatively, immediately after surgery, and I month, 3 months, and 6 months postoperatively. The 2 groups were then compared statistically.Results: in the comparison of the time-course change between the 2 groups with repeated measure analysis of variance, there were significant differences in occlusal plane (between subjects, F = 2.517; df = 4; P = .0437) and convexity (between subjects, F = 4.048; df = 4; P =.0038). However, there was no significant difference in the other measurements.Conclusion: This study suggested that in most measurements, there was no significant difference between 2 groups with and without an IMF screw in time-course skeletal change. However, use of IMF screws was helpful for orthognathic surgery as a rigid anchor of IMF. (c) 2007 American Association of Oral and Maxillofacial Surgeons.
