    This study introduces a novel method for digitizing mandibular movement recordings using photography and computer analysis. The technique demonstrates reliable accuracy, paving the way for detailed occlusal studies.

    Area of Science:

    • Biomechanical Engineering
    • Dental Technology
    • Computer Science

    Background:

    • Accurate recording and analysis of mandibular movements are crucial for understanding occlusion and dental health.
    • Existing methods for capturing mandibular motion may lack precision or efficiency.

    Purpose of the Study:

    • To describe and validate a new method for transferring engraved mandibular movement recordings into computer memory.
    • To assess the reliability and accuracy of this photographic and digital data transfer technique.

    Main Methods:

    • Engraved blocks of mandibular movement recordings were photographed using a specialized platform for uniform imaging.
    • Photographed data were projected onto graph paper, traced, and the centric point labeled.
    • Traced data were digitized into computer memory using a Computek 531 tablet.

    Main Results:

    • A root-mean-squared (RMS) deviation test was performed to evaluate the method's reliability.
    • The maximum deviation observed was 0.363 mm for the z-coordinate of the left-side recording.
    • Labeling the centric point in the digital record is critical for detailed analysis.

    Conclusions:

    • The described method provides a reliable approach for digitizing mandibular movement data.
    • Accurate digital records facilitate in-depth study of jaw movements, particularly in clinically significant areas.
    • This technique holds potential for clarifying complex issues in occlusion, tooth stability, and periodontal health.
