title: Locating the centric relation prematurity with a computerized occlusal analysis system.
abstract: Locating the first tooth contact that interferes with freedom of movement in and out of centric relation has been the diagnostic and treatment objective of most occlusal therapies. The centric relation prematurity can be located by various methods, which involve operator-guided mandibular positioning combined with the patient's subjective assessment of his or her perceived first tooth contact. The method known as bimanual manipulation has been widely recognized and accepted as a predictable method of determining and verifying the centric relation position. The first occlusal contact that results when the mandible is closed on a correct centric relation axis is known as the centric relation prematurity. An alternative procedure combines bimanual manipulation with the simultaneous recording of the sequence of resultant tooth contacts using a computerized occlusal analysis system. This alternative offers a significant improvement in the precision of locating the first tooth contact. This article describes a method of identifying the first tooth contact while not relying on the patient's subjective assessment of his or her perceived occlusal feel.
