A clutch apparatus includes a mandibular clutch device and a maxillary clutch device. The mandibular clutch device includes a mandibular clutch configured to be affixed to mandibular teeth, a mandibular face bow connected to the mandibular clutch, and first and second collimated light sources connected to the mandibular face bow. The maxillary clutch device includes a maxillary clutch configured to be affixed to maxillary teeth, a maxillary face bow connected to the maxillary clutch, and first and second position-sensitive diodes (PSDs) connected to the maxillary face bow. Each of the mandibular and maxillary face bow is selectively adjustable to position the first and second light sources and the first and second PSDs in a plurality of positions. In an example, the mandibular and maxillary face bow are selectively adjustable to position the first and second light sources and the first and second PSDs proximate right and left bicuspid regions or proximate the actual physiologic axis of rotation of the mandible.

A system and method for modeling bite function. A top pantograph is fixed to a patient via clutches to the top teeth of the patient, a bottom pantograph is fixed to a patient via clutches to the bottom teeth of the patient and the actual bite of the patient is optically monitored by monitoring the relation of the top pantograph to the bottom pantograph during a bite cycle and storing a hinge axis. Data is stored relating to the actual bite and the top teeth are scanned to create a top teeth model while the bottom teeth are scanned to create a bottom teeth model. A digital representation of the top pantograph is digitally fitted to the top teeth, a digital representation of the bottom pantograph bottom pantograph is digitally fitted to the bottom teeth, and the relationship of the top teeth model and the bottom teeth model to the hinge axis is recorded. A bite model is digitally created by recording the position of the top teeth model in relation to the bottom teeth model while digitally moving the bottom teeth model with respect to the top teeth model around the hinge axis.
