Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Maxillofacial Surgery

Background:

  • Accurate 3D reconstruction of facial soft tissue is crucial for effective maxillofacial defect rehabilitation.
  • Developing integrated computer-aided design (CAD) and computer-aided manufacture (CAM) systems can enhance treatment outcomes.

Purpose of the Study:

  • To evaluate the application of light 3D scanning and rapid prototyping for facial soft tissue reconstruction.
  • To establish a foundation for developing CAD/CAM systems for maxillofacial defect rehabilitation.

Main Methods:

  • Facial profiles were scanned using a self-developed light 3D scanning system.
  • Image data was processed using Surfcaq software to obtain point and cloud data.
  • 3D reconstruction was performed using Geomagic Studio 7.0, followed by triangulation and model fabrication via fused deposition modeling (FDM).

Main Results:

  • A complete 3D image of the volunteer's facial soft tissue was successfully generated.
  • A physical 3D resin model of the facial soft tissue was fabricated using rapid prototyping.

Conclusions:

  • Light 3D scanning systems are feasible for accurate 3D reconstruction of facial soft tissues.
  • This technology supports the development of advanced CAD/CAM solutions for maxillofacial rehabilitation.
