Abstract
1 The correct centric relation is essential in complete denture construction. 2 Prosthodontists disagree as to what constitutes centric relation and how it is best registered. 3 The present accepted definition of centric relation is based upon the relationships of the mandibular condyles to the glenoid fossae under normal or ideal conditions. 4 The Gothic arch tracing is the best visual device for ascertaining the horizontal relationships of mandibular positions and two dimensional movements. 5 The Gothic arch tracing does not determine centric relation. 6 A sharp Gothic arch tracing may be obtained with the condyles in more than one location in the glenoid fossae. 7 A method is advocated to utilize and analyze Gothic arch tracings in order to determine centric relation.
