Abstract
Concepts of occlusion in the early twentieth century were based primarily on the rehabilitation of totally edentulous patients with complete dentures. Concepts of centric relation evolved as dentists refined their treatment methods for edentulous patients. The term centric occlusion was not abandoned but was redefined as “the occlusion of opposing teeth when the mandible is in centric relation”, a position that may or may not coincide with maximum intercuspal position (MIP). Developing an MIP that coincides with centric relation provides denture stability in MIP; however, mastication is not restricted to pure hinge movement. Mastication involves lateral, protrusive, and retrusive three-dimensional movements. With further improvements in materials and techniques in the 1960s, it became possible to accurately seat castings that were splinted together. An articulator, which has several functions, is used when restoring a dentition.
