Abstract
Jaw movements are measured mechanically and electrically. The information is used to adjust guide boxes on a dental articulator which cooperate with fixed styluses to simulate jaw movements. The information is also used to select preformed guide blocks with fixed walls. Such preformed guide blocks are adjustably mounted which causes change of the orientation of the fixed walls. Also disclosed is a hinge bracket for use in positioning preformed guide blocks for simple hinging action in an articulator. Further disclosed is a pair of alignment members having laterally extending openings which facilitate lateral adjustment of an articulator upper frame on fixed styluses of a lower frame.
