Occlusion is fundamental to preserving the functional integrity of the stomatognathic system. Conventional techniques for assessing occlusion primarily depend on subjective patient responses and visual judgment, often lacking measurable data concerning the force and timing of occlusal contacts. Introduced in 1984 and now in its tenth generation of software, the T-Scan system offers a computerized, objective, and dynamic method for occlusal evaluation. Utilizing a pressure-sensitive Mylar sensor, the device records the timing and relative intensity of occlusal forces, helping clinicians identify early contacts, imbalanced force distribution, and potential temporomandibular joint issues. The system delivers real-time two-dimensional and three-dimensional visual outputs under both temporal and force analysis settings. Its versatility extends across various dental disciplines, including prosthodontics, implantology, orthodontics, restorative procedures, and post-operative monitoring. T-Scan enhances diagnostic precision, facilitates patient understanding, and may streamline treatment processes. However, it is not without limitations, such as its inability to measure absolute force, variability in sensor performance, and reduced reliability in certain clinical scenarios. Despite these challenges, the system has shown sufficient sensitivity and specificity to be a reliable tool in clinical practice. By enabling more accurate occlusal adjustments and promoting evidence-based treatment planning, T-Scan plays a significant role in advancing contemporary approaches to occlusal diagnostics and care.
Keywords: Computerized Occlusal analysis, Digital Analysis, Dynamic Mapping, T-Scan.
