Description
Summary:Purpose Reference values of occlusal characteristics are needed to interpret the data obtained using the T‐Scan System. This study aimed to establish reference values for and to assess the reliability of, occlusal force distribution in the maximal intercuspal position and the occlusion time in young adults with healthy dentition. Materials and Methods In total 178 adults with natural dentition participated in this retrospective cross‐sectional study, of whom 76 performed a retest session. Several occlusal recordings were obtained from each participant using the T‐Scan system while asking them to bite two or three consecutive times (multi‐bite) or only once (single‐bite) at the maximal intercuspal position. The lateral and anteroposterior occlusal force distribution were determined as percentages in the right and posterior teeth . Occlusion time was measured in seconds. After the occlusal force distribution and occlusion time percentiles were calculated, reliability was assessed by the intraclass correlation coefficient. Results The 5th–95th percentiles for occlusal force distribution were 34%–67% on the right teeth and 55%–94% on the posterior teeth. The 90th percentile for multi‐bite occlusion time was 0.17 s and for single‐bite occlusion time was 0.27 s. The intraclass correlation coefficients for lateral occlusal force distribution, anteroposterior occlusal force distribution, multi‐bite occlusion time, and single‐bite occlusion time were 0.70, 0.68, 0.58, and 0.67, respectively. Conclusions This study generated reference values for key occlusal characteristics (occlusal force distribution and occlusion time) when using the T‐Scan system. These values showed moderate reliability.
