ABSTRACT:
A pair of spaced apart grooves are machined in a plate in correspondence with the movement of a patient's left and right condyles relative to the sockets in which they move. A third groove is also machined in the same plate, equally spaced and remote from the pair of grooves, in correspondence with the minimal separation of the patient's mandibular and maxillary teeth at various lateral and anterior positions. The plate is then attached to a cast of the patient's maxillary teeth and is mounted in an articulator frame on rigid posts which slide in the machined grooves of the plate as the plate is manually moved, thereby reproducing movements corresponding to the patient's closure pathway and condylar topography.
