Summary
Maximal bite force measurements are reproducible over time. Analyzing occlusal force distribution, particularly the load center, offers reliable, objective evaluation for prosthodontic treatment and masticatory function.
Area of Science:
- Biomechanical analysis of masticatory forces.
- Dental diagnostics and prosthodontics.
Context:
- Objective evaluation of prosthodontic treatment requires reliable methods.
- Maximal voluntary clenching (MVC) is a key indicator of masticatory function.
Purpose:
- To investigate the reproducibility of occlusal force distribution during MVC.
- To assess the reliability of the Dental Prescale System for longitudinal evaluations.
Summary:
- Maximal bite forces were measured in 10 subjects twice, 3 years apart, using the Dental Prescale System.
- No statistically significant differences were found in occlusal force distribution or load center location.
- The coefficient of variance for load center location was low (4.0%), indicating high reproducibility.
Impact:
- Maximal bite force measurement and occlusal force distribution analysis are valuable for longitudinal evaluation of masticatory function.
- Analysis of the occlusal load center is a highly reliable method for evaluating prosthodontic treatment outcomes.
