Analysis of two methods for occlusal contact registration with the T-Scan system

Area of Science:

• Dentistry
• Biomechanical Engineering
• Dental Technology

Background:

• The reproducibility of occlusal contact analysis using the T-Scan system has yielded conflicting results among various researchers.
• Accurate occlusal analysis is crucial for diagnosing and treating dental conditions.
• The T-Scan system offers a digital approach to evaluating occlusal forces and timing.

Purpose of the Study:

• To analyze the T-Scan system's value as a method for exploring occlusal contacts.
• To compare the number of occlusal contacts recorded in different T-Scan operational modes.
• To assess the impact of mandibular positions on occlusal contact measurements.

Main Methods:

• The number of occlusal contacts was recorded in 31 subjects using two T-Scan operational modes (time and force analysis).
• Measurements were taken in four mandibular positions: maximum intercuspation, edge-to-edge, right laterality, and left laterality.
• Analysis of variance (ANOVA) was employed to compare the average number of tooth contacts between modes and positions.

Main Results:

• A significant difference in the number of occlusal contacts was observed for each patient across various mandibular positions.
• The T-Scan system's time analysis mode recorded a proportionally greater number of occlusal contacts compared to the force analysis mode.
• Patient-specific variations in occlusal contact patterns were significant in both analysis modes.

Conclusions:

• The T-Scan system's operational mode significantly influences the recorded number of occlusal contacts.
• Understanding these differences is vital for accurate interpretation of T-Scan data in clinical practice.
• Further research may be needed to standardize T-Scan protocols for optimal diagnostic reliability.
