In In vivo evaluation of T-Scan in quantifying occlusal contact, the researchers sought to evaluate the reliability and validity of T-Scan system for quantitatively measuring occlusal contact area and occlusal contact number.

They concluded that T-Scan method showed strong reliability for measuring OCA and OCN quantitatively. Strong correlations were found between OCA values from TSO and STA method, but the validity of TSO for measuring OCN needs to be promoted.

Clinical significance: T-Scan system demonstrates good potential in quantitative analysis of occlusion, which will expand its clinical application.
