This study investigated variations in occlusal prematurities and condylar positions using different methods of determining centric relation. Thirty patients were randomly placed into three groups of 10. In Group I a clinical analysis of occlusal patterns using bilateral mandibular manipulation (BMM) was compared to results with a chin point (CPM) method. Group II compared CPM to an anterior guidance jig (CPJ) method. Group III compared BMM to CPJ. Standardized transcranial oblique radiographs were taken of each temporomandibular joint using CPM and BMM on 10 patients. Condylar position was determined with tracing evaluations and direct measurements of the radiographs. Clinical results indicated that the initial point of contact was located most accurately with CPJ. Both initial contact points and secondary points were disclosed with CPM. The BMM disclosed the most tooth contacts. Contacts were most prevalent on the premolars. Radiographic analyses of condylar positions were inconclusive.
