Abstract
A dental articulator for connecting upper and lower dental models made from dental impressions of teeth and for moving the mandible in opening and closing, protrusive and lateral motions generally comprises upper and lower arms each having a front end for attachment respectively to upper or lower model. The upper arm includes a pair of condylar slots for receiving journals of the lower arm such that the lower arm may perform the opening and closing motion, the protrusive movement, and lateral movement of the mandible. A cantilever spring attached to the upper arm biases the journals toward the centric occlusion position. Slot stops limit protrusive movement and axle stops limit lateral movement.
