Model Surgery for Planning Surgical Movements and Occlusion

Model surgery used to determine direction and distance of surgical movement necessary to achieve desired postoperative occlusion and facial aesthetics. (A) Casts mounted on a semiadjustable articulator. (B) Repositioning of maxillary cast using a precision measuring instrument. Distances of model surgical movements are coordinated between desired facial aesthetics and movements necessary to create the ideal postoperative occlusion. (C) Maxillary cast remounted on a semiadjustable articulator after precision movements have been completed and verified. Intraocclusal wafers are constructed on this final occlusal setup for use at the time of surgery to align osteotomies and dental segments into the desired postsurgical position.
