ABSTRACT:
A method and apparatus for instrumental model analysis employing a mandibular dental model support pivotally carried on a maxillary dental model support to simulate hinge movements of the lower jaw. The mandibular model support includes a base plate with two vertically extending and spaced apart columns, each column supporting a condylar head, the connection line of the two heads defining the instrumental hinge axis. The condylar heads are individually adjustable in a tridimensional manner to vary the position and orientation of the instrumental hinge axis.
