Description

Centric occlusion and intercuspal position are generally defined as the centered con-tact position of the occlusal surfaces of the mandibular teeth against the occlusal surfaces of the maxillary teeth. However, 'centric occlusion' is defined in the Glossary of Prosthodontic Terms, 6th edition as 'the occlusion of opposing teeth when the mandible is in centric relation. This may or may not coincide with the maximum intercuspation'. The terms that express mandibular posi-tion are ambiguous. In particular, the definition of 'centric relation' has changed over time. It has been considered the most posterior position for reproducible transfer recording purposes. The question arose as to whether the position of centric relation was biologically acceptable. I con-cluded that centric relation is the most anterior-superior position of the mandible that is physi-ologically acceptable. This paper discusses centric occlusion and presents a definition.
