下颌骨升支矢状骨切开术是矫治颌面畸形和功能障碍的常用而且提供多项选择的手术方法。学者认为术后维持下颌骨髁状突段在它正确的解剖位置是至关重要的,并为此进行长期的研究.1986年 Luhr 提出在行下颔骨手术时使用“L”或“T”形小夹板固位,本文作者对 Luhr 法作了改进,用两个37mm 的“L”形小夹板从三维方向上对下颌髁状突段进行准确固位。此法已成功地运用于70多例患者。该方法采用一个正中夹板、一个中间夹板和一个手术夹板固位,应用于双领手术病例。对无颞颌关节症状的病例,正中夹板是在患者的可重复解剖正中关系位的
Mandibular ascending branch sagittal osteotomy is commonly used to correct maxillofacial deformities and dysfunction and provides a number of options for surgical procedures. Scholars believe that postoperative maintenance of the mandibular condyles in its correct anatomical location is crucial and long-term research for this purpose.In 1986 Luhr proposed the use of “L” or “T” Small splint retention, the author of the Luhr method has been improved, with two 37mm “L” -shaped splint from the three-dimensional direction of mandibular condyle accurate retention. This method has been successfully applied to more than 70 patients. The method uses a median splint, a middle splint and a surgical splint retention, used in double collar surgical cases. For cases without temporomandibular joint symptoms, the median splint is located in the patient's reproducible anatomical median relationship
