Abstract: A positioning apparatus and method for using the positioning apparatus to position a dental arch model in a dental articulator, simulating the position of dental arch in a skull. The positioning apparatus includes a first member, a second member that slides with respect to the first member, and a third member that slides with respect to the second member. A locating member on the second member and one or more adjustment members on the third member impart an orientation to a mounting surface representative of a plane in which a dental arch lies. A maxillary tray having radio-opaque members may be mounted to the mounting surface. X-ray data obtained while the maxillary tray is engaged with a patient's teeth is used to determine the position and orientation of a dental arch model while said model is engaged with the maxillary tray on the mounting surface.

Abstract: An apparatus for receiving a model of a dental arch of a patient is provided. The apparatus comprises a generally U-shaped base portion and at least three spaced-apart radio-opaque members secured to the base. An extension may project from the base portion and may include a fourth radio-opaque member secured to the extension. The apparatus also includes means for securing the apparatus to a mounting surface. Also provided is a positioning apparatus and method for enabling use of the model-receiving apparatus to position the dental arch model within a dental articulator to simulate the position of the dental arch in a skull. The positioning apparatus includes a first member, a second slidable with respect to the first member and a third member slidable with respect to the second member.
