目的：介绍一种基于咬合的"正颌定位系统"（OPS）的概念和用途，该系统将在正颌外科手术中使用。材料和方法：OPS由术中基于咬合的设备组成，该设备将虚拟手术计划转移到手术区域，用于重新定位截骨的牙骨段。该系统使用连接到咬合夹板的可拆卸引导件。初始钻孔导向器用于建立稳定的参考或标志。这些是在骨上钻孔的，不会在截骨线附近重新定位。在骨骼节段活动后，根据虚拟手术计划，使用最终定位导向器（参考钻孔标志）转移骨骼节段。OPS的数字化设计，使用三维计算机辅助设计/计算机辅助制造技术和制造与stereolithographictechnology.Conclusions：虚拟手术计划提高了术前评估，并与OPS，执行正颌外科手术。OPS可以消除传统正颌手术计划中常见的不准确性，并通过消除手术步骤（例如术中测量、确定髁突位置、使用笨重的中间夹板以及使用颌间钢丝固定）来简化执行。OPS试图将虚拟计划精确地转换到手术区域，从而弥合虚拟手术和实际手术之间的差距。(C)2013年美国口腔颌面外科医师协会J Oral Maxillofac Surg 71：911 - 920，2013
Purpose: To introduce the concept and use of an occlusal-based "orthognathic positioning system'' (OPS) to be used during orthognathic surgery.Materials and Methods: The OPS consists of intraoperative occlusal-based devices that transfer virtual surgical planning to the operating field for repositioning of the osteotomized dentoskeletal segments. The system uses detachable guides connected to an occlusal splint. An initial drilling guide is used to establish stable references or landmarks. These are drilled on the bone that will not be repositioned adjacent to the osteotomy line. After mobilization of the skeletal segment, a final positioning guide, referenced to the drilled landmarks, is used to transfer the skeletal segment according to the virtual surgical planning. The OPS is digitally designed using 3-dimensional computer-aided design/computer-aided manufacturing technology and manufactured with stereolithographic techniques.Conclusions: Virtual surgical planning has improved the preoperative assessment and, in conjunction with the OPS, the execution of orthognathic surgery. The OPS has the possibility to eliminate the inaccuracies commonly associated with traditional orthognathic surgery planning and to simplify the execution by eliminating surgical steps such as intraoperative measuring, determining the condylar position, the use of bulky intermediate splints, and the use of intermaxillary wire fixation. The OPS attempts precise translation of the virtual plan to the operating field, bridging the gap between virtual and actual surgery.
