    This study introduces a FORTRAN program for analyzing dental arch form using cubic splines. The software measures arch length and evaluates fit, aiding orthodontists in assessing space and treatment outcomes.

    Area of Science:

    • Biomedical Engineering
    • Orthodontics
    • Computer Science

    Background:

    • Dental arch form analysis is crucial for orthodontic diagnosis and treatment planning.
    • Accurate measurement of dental arch dimensions is essential for assessing tooth crowding and available space.
    • Existing methods for dental arch analysis may lack precision or efficiency.

    Purpose of the Study:

    • To present a FORTRAN computer program for fitting cubic interpolatory splines to digitized dental models.
    • To enable precise measurement of dental arch length and computation of curve normals for error evaluation.
    • To provide a tool for assessing changes in dental arch form during orthodontic treatment.

    Main Methods:

    • Digitizing photographic reproductions of dental models to obtain data points.

    • Main Results:

    • The FORTRAN program successfully fits cubic splines to dental arch data.
    • The program accurately measures dental arch length, providing an assessment of space availability.
    • Computed normals allow for robust evaluation of the spline fit's accuracy.

    Conclusions:

    • The developed FORTRAN program is a valuable tool for quantitative analysis of dental arch form.
    • Accurate arc length measurement aids orthodontists in evaluating space available for teeth.
    • The program facilitates objective assessment of dental arch changes resulting from orthodontic interventions.
