When using the bilateral sagittal split osteotomy (BSSO) technique, rigid internal fixation (RIF) remains the standard method to accurately fix the distal and proximal osteotomy fragments. A concern with the use of RIF, especially with bicortical screws, is the increased risk of condylar torque and its functional consequences. This technical note introduces a new method for preventing torque of the mandibular condyles after BSSO, using a sagittal split space maintainer.
在使用双侧矢状劈开截骨术（BSSO）时，刚性内固定（RIF）仍然是准确固定远、近骨折块的标准方法。RIF 的使用存在一个问题，特别是双皮质螺钉，其增加了髁突扭矩的风险及其功能后果。本技术说明介绍了一种使用矢状劈开间隙保持器预防 BSSO 后下颌髁突扭矩的新方法。
