Summary

Denture wearers exhibit significantly reduced bite strength and masticatory force compared to natural dentition. Posterior denture tooth form did not impact chewing force, indicating a handicap for denture users.

Area of Science:

  • Dental Science
  • Biomechanical Engineering

Background:

  • Denture use is common among tooth-loss patients.
  • Assessing functional limitations of dentures is crucial for patient quality of life.

Purpose of the Study:

  • To quantify the bite strength and masticatory force in denture wearers.
  • To compare these forces to those of individuals with natural dentition.
  • To investigate the influence of posterior denture tooth occlusal form on masticatory force.

Main Methods:

  • Comparative analysis of bite force measurements.
  • Evaluation of masticatory forces in denture wearers versus natural dentition subjects.

Main Results:

  • Denture wearers possess only 20-25% of the bite strength of natural dentition.

  • A wide variation in bite strength exists within the natural dentition group.
  • Masticatory forces in denture wearers are substantially lower than the natural dentition range.
  • Occlusal form of posterior denture teeth showed no significant effect on masticatory force.

    • Conclusions:

    • Denture wearers experience a significant handicap in bite force and masticatory function.
    • Current denture designs may not fully restore chewing efficiency.
    • Further research into denture design optimizing occlusal forces is warranted.
