TLDR
T-Scan is good for assessing occlusion discrepancies and can be used to portray the pre- and post-operative occlusal contact distribution during treatment planning and follow-up, and was better after surgery than before surgery.Abstract:
Dental occlusion varies among individuals, and achieving correct physiological occlusion after osteotomy is essential for the complex functioning of the stomatognathic system. The T-Scan system records the centre of force, first contact, maximum bite force, and maximum intercuspation. The aim of the present study was to investigate the usefulness and consistency of T-Scan in assessing occlusion before and after orthognathic surgery. Occlusal information was evaluated for 30 healthy adults with normal occlusion and 40 patients undergoing orthognathic surgery. T-Scan had a high degree of reliability for consecutive measurements (Pearson correlation, r = 0.98). For most parameters, occlusal distribution was better after surgery than before surgery. More teeth contributed to occlusion at maximum intercuspation after surgery than before surgery (14 vs. 10). In addition, the difference in the posterior force distribution was reduced after surgery (17.6 ± 13.8 vs. 22.7 ± 21.4 before surgery), indicating better occlusal force distribution after surgery. The maximum percentage force on teeth (p = 0.004) and the number of teeth contributing to occlusion (p < 0.001) also differed significantly. Thus, T-Scan is good for assessing occlusal discrepancies and can be used to portray the pre- and post-operative occlusal contact distribution during treatment planning and follow-up.read more

T-scan system in the management of temporomandibular joint disorders – A review
TL;DR: T-scan computerized Occlusal analysis technology eliminates the process of subjective interpretation of occlusal contacts obtained using articulating paper marks and precisely pinpoints the excessively forceful contact locations and displays them for analysis in a colourful three-dimensional view thus helping the diagnostician to understand the overall occlical force distribution.
