Abstract

In order to create denture occlusion that is functional, comfortable and balanced, it is necessary to both determine a vertical dimension of occlusion that is in harmony with the patient's musculature and to record a relatively repeatable jaw relation position. This require clinical skill to establish an accurate, verifiable and reproducible vertical dimension of occlusion (VDO) and centric relation (CR). Correct vertical relation depends upon a consideration of several factors, including muscle tone, inter-dental arch space and parallelism of the ridges. Centric relation is considered to be a repeatable position from which all opening and lateral mandibular movements begin and recording this position is a critical step in the fabrication of dentures. Any errors made while taking maxillo-mandibular jaw relation records will result in denture that are uncomfortable. The purpose of this paper is to review a very simple and efficient technique for accomplishing these two important steps in denture fabrication.
