ABSTRACT:
A method and apparatus for monitoring, storing and displaying movements of a person's mandible in relation to the cranium, comprises a plurality of infrared LED's securely mounted to the cranium and to the jaw, in immovable relation to the mandible. The location of each LED, as determined by photodiodes as the LED's are sequentially turned on and off, is compared against an established three dimensional system frame of reference and through distinct local frames of reference associated with the cranium and the jaw, respectively, within the system frame of reference. A pointer, also provided with LED's is used to locate specific points on the mandible in reference to the movement described by the LED's attached to the lower jaw. The data is collected, calibrated and stored by a computer for subsequent display and analysis, either alone or in conjunction with a video display of the person's actual head and jaw as the data was taken.
