This study measured maximal bite forces using a new electronic gnathodynamometer. Results showed significant differences in bite force between males and females, particularly in the anterior region, and between anterior and posterior teeth.

Area of Science:

  • Biomechanical Engineering
  • Dental Physiology
  • Human Performance Measurement

Background:

  • Masticatory function is critically assessed by bite force.
  • Understanding bite force dynamics is essential for dental diagnostics and prosthodontics.
  • Previous measurements lacked the precision of modern electronic devices.

Purpose of the Study:

  • To evaluate maximal bite forces in individuals with complete dentition.
  • To analyze the time-dependent force exertion (50% and 75% of total force).
  • To characterize bite force curves and their correlation with gender and age.

Main Methods:

  • Utilized a newly developed electronic gnathodynamometer for precise measurements.
  • Collected data on maximal bite forces, force exertion times (T1, T2), and bite curve shapes.

  • Performed statistical analysis (ANOVA) to compare forces based on gender and age.

    • Main Results:

    • No significant correlation found between bite force values and subject age.
    • Significant differences in bite forces were observed between males and females, especially in the anterior segments.
    • Distinct differences noted between anterior and posterior tooth bite forces, with statistically significant time correlations for posterior and anterior teeth.

    Conclusions:

    • Bite force measurements, including curve shape, can serve as a diagnostic tool.
    • Findings suggest gender-specific differences in masticatory force exertion.
    • The electronic gnathodynamometer provides valuable data for clinical follow-up and prosthodontic treatment planning.
