Computer Aided Evaluation of Bite Force in Complete Dentures – An in Vivo Study.

Abstract

Introduction: Achieving balanced occlusion in complete denture therapy is critical for comfort, function, and patient satisfaction. Conventional clinical remount procedures are effective but time-consuming and often impractical for elderly patients. This study evaluated the effectiveness of selective grinding guided by digital occlusal analysis using the digital system in improving bite force distribution in complete denture wearers.

Objectives: To evaluate and compare occlusal force percentage in complete dentures.

Methods: A clinical observational study was conducted on 10 completely edentulous patients aged over 40 years, rehabilitated with conventional complete dentures. Following laboratory remounting, occlusal force distribution was recorded using the OccluSense system. High-pressure contact points were identified digitally and clinically and adjusted through selective grinding. Bite force distribution was recorded before and after the adjustment. Statistical analysis included the Statistical analysis used: paired t-test, Mann-Whitney U test, and Kruskal-Wallis test.

Results: The mean bite force on the left side increased from 46.10 ± 2.96 to 48.30 ± 1.95, while on the right side it decreased from 53.90 ± 2.96 to 51.70 ± 1.95. The changes were statistically significant (p < 0.005), indicating effective redistribution of occlusal forces. No significant differences were observed across gender or age groups.

Conclusions: Selective grinding based on digital occlusion analysis with OccluSense significantly improved occlusal force distribution in complete denture wearers. This approach provides a practical, efficient, and patient-friendly alternative to conventional clinical remounting. However, larger sample sizes and long-term follow-up are recommended to validate these findings.
