[Normal occlusion study: using T-Scan III occlusal analysis system].

Area of Science:

• Dental Occlusion
• Biomechanics
• Oral Physiology

Context:

• Normal occlusion is crucial for masticatory function and overall oral health.
• Accurate measurement of occlusal forces and timing is essential for diagnosing and treating occlusal disorders.
• The T-Scan III occlusal analysis system provides objective data on occlusal contacts and force distribution.

Purpose:

• To investigate the normal occlusal force distribution and occlusion time characteristics at different positions using the T-Scan III system.
• To identify the primary areas of force concentration during intercuspal, protrusive, and lateral excursive positions.
• To analyze the temporal dynamics of occlusal contact and disclusion in healthy individuals.

Summary:

• Fifty-three volunteers with normal occlusion were analyzed using the T-Scan III system.
• Results indicate molar teeth bear the most force at the intercuspal position, with significant left-right asymmetry.
• The incisor region (21, 12) showed concentrated force during protrusion, and lateral occlusion patterns were diverse, including cuspid-protected, group functional, and multiple-protected types.

Impact:

• Findings provide normative data for occlusal force distribution and timing in healthy adults.
• This research can aid in the diagnosis and management of occlusal discrepancies and temporomandibular joint disorders.
• Establishes a baseline for understanding how occlusal forces are distributed and managed during various jaw movements.
