T-Scan Digital Occlusal Analysis in Dentistry: Principles, Clinical Applications, Evidence, and Future Perspectives

Abstract

Occlusal analysis is a fundamental component of diagnosis and treatment planning in dentistry, influencing the longevity, function, and comfort of both natural dentition and prosthetic rehabilitations. Conventional occlusal indicators such as articulating paper, waxes, and shimstock foils identify contact locations but do not quantify occlusal force or provide information regarding the sequence and timing of tooth contacts. Computerized occlusal analysis using the T-Scan system has emerged as an objective and dynamic method for evaluating occlusal relationships by recording relative occlusal force distribution, contact timing, occlusion time, disclusion time, and the center of force during mandibular function. The present review summarizes the principles, technological evolution, clinical applications, current evidence, limitations, and future prospects of T-Scan technology across various dental specialties. A comprehensive literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar for English-language publications from January 1990 to July 2026. Relevant clinical trials, observational studies, in vitro investigations, systematic reviews, narrative reviews, and consensus publications were identified using predefined search terms related to computerized occlusal analysis and T-Scan technology. Studies were screened for relevance, and data were synthesized narratively according to dental specialty and clinical application. Current evidence suggests that T-Scan enhances diagnostic accuracy, facilitates precise occlusal adjustment, improves implant occlusion management, supports temporomandibular disorder assessment, and contributes to predictable prosthodontic rehabilitation when used alongside conventional clinical examination. Although limitations including equipment cost, sensor wear, and the inability to directly visualize contact markings remain, ongoing advances in digital dentistry, artificial intelligence, and virtual articulators are expected to further expand the role of computerized occlusal analysis in contemporary dental practice.
