Area of Science:

  • Medical Imaging and Computer-Aided Design
  • Biomedical Engineering
  • Prosthodontics

Context:

  • External nasal defects pose significant challenges in prosthodontic rehabilitation.
  • Accurate digital reconstruction of nasal morphology is crucial for functional and aesthetic outcomes.
  • Existing methods may lack precision in capturing patient-specific facial features.

Purpose:

  • To develop and validate a 3D facial morphology completion method for external nasal defects.
  • To utilize non-rigid registration of 3D face templates for personalized nasal prosthesis design.
  • To assess the accuracy and feasibility of the proposed digital design solution.

Summary:

  • A novel method employing non-rigid registration of 3D face templates was used to complete external nasal defects in 20 male patients.
  • The technique involved deforming a 3D face template to match the patient's non-defective facial areas, followed by cutting out the reconstructed nose.
  • Quantitative analysis showed no significant differences in nasofacial and nasolabial angles, with high accuracy in edge fit and morphological similarity to original data.

Impact:

  • Provides a feasible and accurate digital solution for designing custom nasal prostheses.
  • Enhances patient-specific treatment planning in prosthodontics for nasal reconstruction.
  • Improves the aesthetic and functional outcomes for individuals with external nasal defects.
