Summary
This study presents a novel, simple surgical guide for genioplasty. The computer-aided design and manufacturing (CAD/CAM) guide accurately guided osteotomy and bone segment repositioning during surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomedical Engineering
- 3D Printing in Medicine
Background:
- Genioplasty surgery requires precise bone cutting and repositioning.
- Existing methods may lack accuracy or simplicity.
- A need exists for improved surgical aids in genioplasty.
Purpose of the Study:
- To design and fabricate a simple surgical guide for genioplasty.
- To utilize 3D modeling and printing for surgical planning and execution.
- To enhance accuracy and efficiency in genioplasty procedures.
Main Methods:
- 3D reconstruction of cranio-maxilla from CT DICOM data.
- In silico surgical simulation and planning using 3D cephalometry.
- Computer-aided design (CAD) and computer-aided manufacturing (CAM) for surgical guide fabrication.
- 3D printing of the custom surgical guide.
- Intraoperative use of the guide for osteotomy and bone segment manipulation.
Main Results:
- Successful osteotomy performed as planned during genioplasty.
- The CAD/CAM surgical guide facilitated accurate bone cutting and repositioning.
- The fabricated guide was effectively used in actual patient surgery.
Conclusions:
- The developed surgical guide is a simple and practical tool for genioplasty.
- It assists surgeons in accurate bone segment manipulation.
- Preoperative 3D planning and the surgical guide enhance surgical outcomes.
