Location of the terminal hinge axis by intraoral means.

Abstract An intraoral technique for locating the terminal hinge axis has been described. The key to the success of this technique lies in the accurate location of centric relation at 2 different degrees of jaw separation. Centric relation can be located by many techniques but there is some variability in the results obtained by any of them. Therefore, each dentist should have a means of comparing his registrations so that an intelligent selection can be made. The Buhnergraph and the technique described here provide a means of locating centric relation and determining and/or verifying the location of the terminal hinge axis.
