ABSTRACT:
An articulator having an upper frame having an upper arm and a lower frame having a lower arm. A pivot is provided on the upper arm swingably supporting the upper frame on the lower frame. Adjusting mechanism is provided for adjusting the upper arm relative to the lower arm so that a casting supported on the upper arm can be rotated relative to the lower arm or tilted up and down, forward and laterally, as well as swinging the upper casting relative to the lower casting. The dental articulator simulates the operation of human jaws for use in the manufacture of false teeth. An upper frame representing the upper jaw is mounted to a lower frame by a pair of ball and socket joints which may be adjusted to approximate a specific patient's jaw hinge. The adjusting mechanism can include a computer controlled motor for adjusting the upper arm relative to the lower arm in accordance with X-ray data of a patient's jaw structure.
