Summary
Artificial intelligent splints significantly improve the efficiency of orthognathic surgery splint design. This AI-driven approach saves time and maintains accuracy compared to traditional digital splints.
Area of Science:
- Biomedical Engineering
- Dental Surgery
- Artificial Intelligence
Background:
- Digital splints are crucial in orthognathic surgery but suffer from time-consuming design processes and low reproducibility.
- Current methods present challenges in efficiency and consistency for surgical planning.
Purpose of the Study:
- To develop and evaluate an artificial intelligence (AI) algorithm for the automatic design of splints in orthognathic surgery.
- To assess the efficiency, accuracy, and reproducibility of AI-driven splint design compared to traditional digital splints.
Main Methods:
- An AI algorithm and program for splint design were created.
- 54 patients with skeletal class III malocclusion underwent pre and postoperative radiographic examinations.
- Cephalometric measurements compared virtual simulations with postoperative images; time costs and differences were analyzed.
Main Results:
- AI-driven splint design significantly improved efficiency.
- The mean difference between AI splints and digital splints was <0.15 mm in model surgery.
- No significant difference in accuracy was observed between AI and digital splints in radiological image analysis.
Conclusions:
- AI splints offer a time-saving advantage for presurgical design in orthognathic surgery without compromising accuracy.
- The AI approach is considered beneficial for enhancing presurgical planning in orthognathic procedures.
- This technology promotes greater accessibility and efficiency in custom splint fabrication.
