Custom adaptation of an occlusal plane analyzer to a semiadjustable articulator

The use of a semiadjustable articulator has become more popular for prosthodontic rehabilitation. An occlusal plane analyzer has long been used to assist the operator in the development of an initial mandibular occlusal plane in diagnostic contour casts and later as an integral part of both the contours of the definitive restorations as well as guidelines for the actual tooth preparations. Many manufacturers of semiadjustable articulators offer no such occlusal plane analyzers for use with their instruments. This article describes modifications for the adaptation of an occlusal plane analyzer to the WhipMix 2240 semiadjustable articulator, a possibility heretofore unavailable from any manufacturer.
