Area of Science:

  • Dental Science
  • Biomedical Engineering
  • Prosthodontics

Background:

  • Complete dentures require precise occlusal analysis for optimal function.
  • Existing methods for occlusal analysis may lack accuracy or comprehensive data capture.

Purpose of the Study:

  • To evaluate the efficacy of a novel occlusal analysis system for complete denture wearers.
  • To assess the system's ability to measure occlusal pressure and discriminate between adjusted and non-adjusted dentures.

Main Methods:

  • Laboratory evaluation of the Dental Prescale System's accuracy in measuring applied loads.
  • Clinical assessment of occlusion in 100 complete denture wearers (50 non-adjusted, 50 adjusted) using the system.
  • Analysis of five occlusal parameters and error discrimination rate between groups.

Main Results:

  • The system demonstrated a tendency to register higher values than actual applied loads in laboratory tests (mean difference 6.3 +/- 10.6 N).
  • An error discrimination rate of 16% was observed between groups wearing adjusted and non-adjusted complete dentures.
  • The system successfully measured occlusal pressure at individual contact points.

Conclusions:

  • The new occlusal analysis system is a valuable tool for quantitative occlusal analysis in complete denture patients.
  • The system shows potential for effective patient screening and identifying occlusal discrepancies.
  • Further refinement may improve the accuracy of pressure measurements.
