Summary
Computer-assisted surgical simulation (CASS) streamlines orthognathic surgery planning and splint fabrication. This technology offers comparable or superior splint fit and identifies discrepancies missed by traditional methods.
Area of Science:
- Oral and Maxillofacial Surgery
- Medical Imaging
- Computer-Aided Design
Background:
- Orthognathic surgery corrects jaw skeletal discrepancies but involves laborious traditional model surgery and splint fabrication.
- Computer-assisted surgical simulation (CASS) has been proposed to simplify these processes.
Purpose of the Study:
- To evaluate the implementation and effectiveness of a CASS system for treatment planning and surgical splint fabrication in orthognathic surgery.
Main Methods:
- A CASS system was used for treatment planning and splint fabrication in 11 orthognathic surgery patients.
- Traditional model surgery and splint fabrication were performed concurrently as a safety measure.
- Evaluation included cephalometric analysis accuracy, splint accuracy and durability, and treatment planning efficiency.
Main Results:
- CASS-fabricated splints demonstrated equal or superior fit compared to traditional methods.
- The CASS system detected occlusal canting in 2 cases missed by conventional analysis.
- Skeletal and soft tissue midline discrepancies were identified and managed through combined CASS and clinical assessment.
Conclusions:
- The CASS system is an effective tool for treatment planning and surgical splint preparation in orthognathic surgery.
- CASS enhances accuracy and efficiency, potentially improving patient outcomes.
