Researchers created a detailed 3D digital model of the mandible using cadaver data. This provides valuable morphological information for diagnosing and surgically treating mandible diseases.

Area of Science:

  • Anatomical modeling
  • Medical imaging
  • Digital reconstruction

Background:

  • Accurate anatomical data is crucial for diagnosing and treating mandible diseases.
  • Existing methods may lack the detailed morphological insights required for complex surgical planning.

Purpose of the Study:

  • To construct a precise, visible, three-dimensional (3D) digital model of the human mandible.
  • To generate comprehensive morphological data for enhanced diagnosis and surgical intervention of mandibular conditions.

Main Methods:

  • A male adult cadaver specimen was processed through fixation, perfusion, refrigeration, embedding, and sectioning at 0.1 mm intervals.
  • Mandible and tooth outlines were digitized from serial cross-sections using Adobe Photoshop 8.0.
  • A 3D model was reconstructed using Amira software, incorporating cross-sectional data.

Main Results:

  • A highly accurate and detailed 3D digital model of the mandible was successfully generated.
  • The model vividly displays the anatomical structures of the mandible and teeth in three dimensions.
  • The mandibular nerve canal's location and trajectory are clearly visualized within the transparent model.

Conclusions:

  • The study successfully obtained complete and precise cross-sectional data of the mandible.
  • Amira reconstruction software facilitates the effective visualization of the mandible.
  • The reconstructed 3D model accurately represents the natural anatomical state of the mandible.
