Summary
Computer-aided jaw surgery enhances precision by transferring virtual plans to the operating room. This advanced system improves surgical planning, intraoperative guidance, and patient outcomes in complex cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Imaging
- Computer-Aided Surgery
Background:
- Traditional jaw surgery planning can lack precision.
- Transferring virtual surgical plans to the operating room presents challenges.
- There is a need for integrated systems to improve accuracy and efficiency in maxillofacial procedures.
Purpose of the Study:
- To discuss the development of computer-aided methods for precise jaw surgery.
- To present a comprehensive computer-aided surgery system for maxillofacial procedures.
- To highlight the benefits of advanced software in surgical planning and execution.
Main Methods:
- Construction of 3D surface models from cone-beam computed tomography (CBCT).
- Dynamic cephalometry, semiautomatic mirroring, and interactive bone cutting.
- Virtual surgical planning, including bony segment repositioning and manufacturing of positioning splints.
- Real-time intraoperative guidance using computer displays and 3D positioning guides.
Main Results:
- The developed system enables high precision in transferring virtual plans to the operating room.
- Computer-aided surgery facilitates complex case management and improves surgical accuracy.
- Advanced software enhances diagnosis, treatment planning, and surgical resident training.
Conclusions:
- Computer-aided surgery offers significant benefits for patients, surgical practice, and orthodontic finishing.
- The system increases the flexibility, detail, and accuracy of surgical plans.
- Enhanced operative precision, control, and case documentation are key advantages.
