Evaluation of occlusal contacts in maximum intercuspation using the T-Scan system.

Different authors have questioned the reliability of the T-Scan system as a method for registering occlusal contacts. The number of tooth contacts resulting from four bites made in maximum intercuspation was analysed with T-Scan using time moment statistics. The results indicate that (1) the largest number of contacts occur in the molar region (2) variability between subjects is greater than variability within subjects, and (3) it is possible to identify the subject being tested in 90.3% of cases. The T-Scan system has proved to be a reliable method for the analysis and evaluation of occlusal contact distribution in maximum intercuspation.
