Progress in orthodontics·2025

This study presents a new computerized system for orthodontists to analyze dental arch changes over time. The software quantifies variations in arch dimension and form, aiding treatment evaluation and research.

Area of Science:

  • Orthodontics
  • Biomedical Engineering
  • Dental Imaging Analysis

Background:

  • Analyzing changes in dental arch form and dimension is crucial for orthodontic diagnosis and treatment planning.
  • Existing methods may lack the precision or comprehensive analysis required for detailed longitudinal studies.

Purpose of the Study:

  • To introduce a novel computerized method for quantifying dental arch form and dimension variations.
  • To provide orthodontists and researchers with a tool for objective analysis of dental arch changes.

Main Methods:

  • A two-part system comprising a database for scanned dental cast images and analysis software.
  • Software identifies landmarks, calculates distances (widths, curve axis), and measures arch length using various curve-fitting algorithms.

  • Statistical analysis, including Euclidean Distance Matrix Analysis (EDMA) and Bootstrap analysis, differentiates shape and dimension changes.

    • Main Results:

    • The system enables the comparison of dental cast data over time to assess changes in arch dimensions and form.
    • It allows for separate evaluation of dimensional (length, width) and shape variations.
    • The method provides quantitative data on dental arch alterations in untreated subjects and orthodontic patients.

    Conclusions:

    • The developed computerized method offers a robust approach for orthodontists and researchers to evaluate dental arch variations.
    • This tool can enhance understanding of dental arch changes during growth, aging, and orthodontic treatment.
    • The findings contribute to the body of knowledge on dental arch dynamics and orthodontic outcomes.
