This study compared 3D morphometric methods for malocclusion. Multisectional spline (MS) analysis offered the most reliable diagnostic information for evaluating dental and skeletal morphology.

Area of Science:

  • Dentistry and Oral Health
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Three-dimensional (3D) morphometrics are crucial for analyzing complex anatomical structures.
  • Evaluating the diagnostic efficacy of various 3D morphometric techniques in clinical settings is essential.
  • Malocclusion presents significant challenges in orthodontic diagnosis and treatment planning.

Purpose of the Study:

  • To compare the morphological informative value of prominent 3D morphometric methods.
  • To assess the diagnostic utility of these methods in a clinical case study of malocclusion.
  • To identify the most reliable method for analyzing craniofacial morphology in patients with malocclusion.

Main Methods:

  • Conventional cephalometric analysis (CCA)

  • Generalized Procrustes superimposition (GPS) with principal-components analysis (PCA)
  • Thin-plate spline analysis (TPS)
  • Multisectional spline (MS) analysis
  • Clearance vector mapping (CVM)

    • Main Results:

    • Multisectional spline (MS) analysis demonstrated superior reliability and diagnostic value compared to other methods.
    • Conventional cephalometric analysis (CCA) and generalized Procrustes superimposition (GPS) with principal-components analysis (PCA) provided less detailed morphological information.
    • Thin-plate spline analysis (TPS) and clearance vector mapping (CVM) showed moderate diagnostic utility.

    Conclusions:

    • Multisectional spline (MS) analysis is recommended as a highly effective tool for detailed 3D morphological assessment in malocclusion.
    • The findings suggest that advanced 3D morphometric techniques significantly enhance diagnostic capabilities in orthodontics.
    • Choosing the appropriate 3D morphometric method is critical for accurate diagnosis and effective treatment planning in malocclusion.
