Abstract:
An experimental study was conducted to analyze the accuracy of transferring jaw relations with recording materials and the derived casts. A specific measuring system was designed to determine three-dimensional deviations of the condyles of an articulator. Four interocclusal recording materials were analyzed after various storage periods. The results indicated that the accuracy of the derived cast had a critical influence on the accuracy of the transferred jaw relations. None of the materials were reliable; the most accurate material generated deviations of approximately 300 microns.
