Comparison of digital technologies for occlusal analysis in dentate arches: A systematic review.

Abstract

Background: Digital occlusal analysis systems are increasingly utilized to enhance the accuracy and reproducibility of occlusal assessments in dentistry by providing quantitative data on occlusal forces and contact sequences. The variability in the methodologies and outcomes across studies necessitates a systematic evaluation of these technologies.

Objective: This systematic review evaluates the accuracy, reproducibility, and clinical applications of digital occlusal analysis systems in dentate arches.

Methods: MEDLINE/PubMed, Scopus, Web of Science, and Embase databases were searched for articles published up to September 2024. Inclusion criteria encompassed in vitro and clinical studies comparing digital occlusal analysis systems, including T-Scan, OccluSense, Accura, and intraoral scanners.

Results: A total of 3354 articles were identified, of which eight were included. Studies consistently demonstrated superior accuracy and reproducibility of T-Scan systems in dynamic occlusal force assessment. Cerec Omnicam provided reliable static occlusal evaluations, particularly in anterior regions, while OccluSense was an affordable alternative, although reproducibility across various operators and settings was limited. The integration of intraoral scanners with digital occlusal analyzers significantly enhanced diagnostic precision, allowing the simultaneous visualization of occlusal contacts, force distribution, and dynamic sequences. However, variability in the calibration methods and reporting metrics was noted across studies.

Conclusions: Digital occlusal analysis systems, particularly T-Scan, deliver enhanced accuracy and reproducibility for occlusal assessment. Combining systems such as T-Scan with intraoral scanners (Trios or Medit I600) optimizes the clinical outcomes by integrating dynamic force analyses with precise static visualization. Future research should prioritize standardizing methodologies and conducting robust clinical trials to establish comprehensive clinical guidelines.

Clinical significance: This systematic review provides clinicians with evidence-based guidance to select appropriate digital occlusal analysis technologies, which can enhance diagnostic accuracy and patient care.
