A simplified method of recording centric relation contact position (CRCP) using the leaf gauge

Centric relation contact position (CRCP) is the relationship of the maxilla to the mandible when the condyles are in an anterior/superior position in their fossae and tooth contact has just occurred. Provided that the TMJ remains healthy, CRCP is constant and reproducible throughout life and appears to be functionally comfortable. Accordingly, CRCP records serve as a useful reference from which restorative and prosthodontic treatment can be planned.

One frequently reported method of recording CRCP is the bimanual manipulation technique, first described by Dawson.1 This is where the operator supports the patient's mandible during the retruded arc of closure until the first tooth contact (CRCP) is felt by the patient. This process is repeated while the assistant marks CRCP using articulating paper. Some clinicians believe this technique is prone to operator error and that it is difficult to be certain when the mandible is in CRCP using this method.2^,3
