Abstract:
A system and method for determining condyle displacement during jaw articulation includes a physical model with corresponding reference points. The physical model is positioned and scanned to obtain positional data representing a first and second bite position. This positional data is used to generate a transformation matrix. The position of at least one condyle is determined in reference to positional data scanned from the physical model. The transformation matrix is used to map the position of the condyle with respect to the second bite position.
