A novel 3D-printed simulator for hands-on training in orthognathic surgery.

Background: Orthognathic surgery addresses skeletal dysgnathias, enhancing both function and aesthetics. Despite its benefits, potential complications underscore the need for well-trained surgeons. 3D-printed anatomical models, a product of additive manufacturing, aid surgical education, especially for young surgeons lacking on-the-job training. This study focuses on an economically designed 3D-printed simulator for orthognathic surgery training.

Results: Evaluation from 31 participants of two orthognatic surgery workshops using the 3D-printed simulator highlighted positive assessments for realism (7.16 ± 2.03/10) and usefulness in training for specific procedures. While commended for simulating limited oral cavity movements and providing a realistic general simulation, soft tissue realism (4.51 ± 2.66/10) suggested room for improvement. Notably, the simulator demonstrated outstanding cost-efficiency (€ 181.55), with reusable components.

Conclusions: The 3D-printed simulator offers a realistic, cost-effective tool for orthognathic surgery training, despite soft tissue realism limitations. The study anticipates further enhancements in 3D-printing technology to address these aspects and advance future iterations.
