PC-based Virtual Reality Surgical Simulation for Orthognathic Surgery

چکیده
Complex maxillofacial deformations continue to present challenges in analysis, planning and correction beyond modern technology. The purpose of this paper is to present a virtual reality environment for surgeons to perform virtual orthognathic surgical planning in three dimensions. A surgical planning system, “PC-based virtual reality surgical simulation for orthognathic surgery” (VRSSOS), consists of four major stages: CT data post-processing and reconstruction; 3D color facial soft tissue model generation; virtual osteotomy planning; and, soft-tissue-change simulation. The surgical planning and simulation are based on 3D CT reconstructed bone model, whereas the soft tissue prediction is based on color texture-mapped and individualized facial soft tissue model. Our approach is able to provide a quantitative osteotomy -simulated bone model and prediction of post-operative appearance with photo-realistic quality. The predicted appearance can be visualized from any arbitrary viewing point using a low-cost PC-based system.

Using three-dimensional (3D) computerized simulation systems has enabled us to determine the anticipated position of the maxilla and mandibular proximal and distal segments. The bony segments need to be mobilized according to the planned final position. The concept of 3D surgical planning in orthognathic surgery has evolved continuously. While using 3D simulation for planning the correction of ...

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 a...
