Abstract:

A surgical dental articulator having a pivotable frame to which a pair of independently adjustable cantilevers carrying opposed dental casts are mounted. The dental casts are mounted to the cantilever for movement along the cantilever axis and for pivotal movement about a first pivot axis normal to the cantilever axis. The cantilevers are each mounted to the frame by a cantilever support assembly which includes linear support and pivot assemblies. The linear support assembly includes a first transverse support fixedly mounted to the frame and defining a first linear path and a second transverse support slidably mounted to the first transverse support for movement parallel to the first linear path and defining a second linear path perpendicular to the first linear path. The pivot assembly is slidably mounted to the second linear support along the second linear path via a pair of pivot arms. The cantilever is pivotably mounted to the pivot assembly for rotation about the cantilever axis and about a second pivot axis perpendicular to the longitudinal axis.
