Abstract: This invention is a method and an apparatus to assist in accurate placement of teeth and jaws of a patient during orthognathic surgery. An indicator member when independently inserted into the slot of the teeth indexing member assists in designing and making osteotomies relative to the reference planes.

Abstract: A method and apparatus to assist in accurate placement of teeth and jaws at orthognathic surgery. A recording of reference planes used prior to surgery to plan desired changes to an original position of teeth and jaws of a patient is made with a teeth indexing member. The teeth indexing member has a horizontal slot and scribe lines indicating the orientation of the reference planes. During surgery, the recording of the reference planes is transferred to the patient by positioning the teeth indexing member onto the patient's teeth. A swivel member is attached to the patient's head by a cranial structure. A port in the swivel member is oriented to the reference planes by inserting a coupling member into the horizontal slot of the teeth indexing member and into the port of the swivel member, aligning the coupling member to the scribe lines on the teeth indexing member, and securing the oriented swivel member in place. The port thereby records the reference planes.
