Claim One:
1. A method for determining condyle displacement for a patient, the method comprising: mounting a first physical model onto a first scanning plate module to form a first mounting arrangement, the first physical model being representative of a first set of teeth of the patient; mounting a second physical model onto a second scanning plate module to form a second mounting arrangement, the second physical model being representative of a second set of teeth of the patient; positioning the first and second mounting arrangements on a base plate module to arrange the first physical model relative to the second physical model within a coordinate system of a scanning device according to a first bite record; scanning three or more reference sites on at least one of the mounting arrangements with the scanning device to obtain a first set of positional data; positioning the first and second mounting arrangements on the base plate module to arrange the first and second physical models within the coordinate system of the scanning device according to a second bite record; scanning the three or more reference sites with the scanning device to obtain a second set of positional data; determining a transformation matrix from the first and second sets of positional data with a data processing system; determining a first location of a point corresponding to a condyle of the patient in relation to the first set of positional data; determining with the data processing system a second location of the point corresponding to the condyle in relation to the second set of positional data based on the transformation matrix; and generating a manipulable electronic model based on the first and second sets of positional data and the transformation matrix to assess condyle displacement of the patient.
