Abstract: The simulator includes an upper and lower facebow for mounting on a patient to record and later reproduce the three dimensional movements of the patient's mandible. The upper frame has two receptacles mounted thereon having a bore opening toward the anterior portion of the facebow. A molding material is disposed within the receptacles and the lower frame has two styli projecting into the receptacles for indenting the molding material to make an innerocclusal record during the movement of the patient's mandible. The frames are then removed and dental casts are affixed to the frames. The innerocclusal record formed in the molding material is used to reproduce all of the patient's mandibular movements.

Abstract: The simulator includes a maxillary and mandibular facebow, a maxillary and mandibular support and an incisal pin. Receptacles are mounted on the ends of the side arms of the maxillary facebow, and the side arms of the mandibular facebow have styli disposed thereon projecting into the receptacles of the maxillary facebow. Means are provided on both the facebows for the attachment of labial cores and/or bite rims and means are provided on both the supports for the attachment of study casts.The invention also includes a method, using the simulator to record jaw movements.
