An apparatus for use in dentistry to obtain positional data related to movement of a mandible about a maxilla comprises a rigid support frame for supporting a maxilla support member, a positionable mandibular member and sensing assemblies. The support member fixedly attaches to the support frame. The mandibular member is positionable proximate the maxilla member. The sensing assemblies attach to the support frame and connect to the mandibular member to obtain positional data related to the movement of the mandibular member. The positional data is collected by a computing device and stored in a data storage medium as time history files. The files can then be transformed into usable information to replicate the mandibular movement in real time either virtually or mechanically.

Apparatus and method for recording mandibular movement

An apparatus to replicate and analyze movement of a mandible relative to a maxilla with dental casts thereof includes a base frame, an arm connected to the base frame and a suspension assembly positionable by a plurality of electro-mechanical actuators. The arm connects to the base frame and supports the dental cast of the maxilla in a fixed position relative to the base frame. The suspension assembly, having opposing first and second sides, supports the dental cast of the mandible in working relation to the dental cast of the maxilla. The plurality of actuators each selectively impart movement to the sides of the suspension assembly such that the movement of the mandible obtained during a recording process can be replicated on the apparatus in real time.
