    This study measured biting pressure and force in molars, finding higher than expected maximum biting pressure and force. Thinner pressure sheets likely contributed to these elevated biting force measurements.

    Area of Science:

    • Biomechanical Engineering
    • Dental Mechanics
    • Human Physiology

    Background:

    • Understanding molar biting forces is crucial for dental research and prosthetics.
    • Previous studies have established baseline biting force ranges.
    • Variations in measurement techniques can influence reported biting force values.

    Purpose of the Study:

    • To accurately measure biting pressure distribution and biting force in normal molars.
    • To compare measured biting forces with previously reported values.
    • To investigate the impact of measurement tools on biting force outcomes.

    Main Methods:

    • Utilized pressure measuring sheets for biting pressure distribution analysis.
    • Conducted biting force measurements on normal molar teeth.

  • Employed thinner sheets to potentially enhance measurement sensitivity.

    • Main Results:

    • Maximum biting pressure was recorded between 700-800 kg/cm².
    • Maximum biting force for 6th and 7th teeth exceeded 100 kg.
    • Observed higher values compared to prior research, attributed to thinner sheets.

    Conclusions:

    • Normal molars can generate significant biting pressure and force.
    • The use of thinner pressure sheets may lead to higher recorded biting force values.
    • Further research should consider the influence of measurement material thickness on biting force quantification.
