(TC80) Impact of 3D-Printed Model Designed for Apicoectomy Training on User’s Knowledge, Confidence, and Interest in The Procedure

Background: Surgical typodonts that simulate failed root canal treatments (RCTs) requiring surgical intervention can cost between $100 and $500 and are consumable, unlike traditional typodonts. As a result, DMD students receive limited hands-on training in apicoectomy procedures before graduation, with many residents performing the procedure on live patients for the first time. This study aimed to create cost-effective surgical training models for root tip resection and assess the impact on participants' knowledge of the procedure, confidence in their ability to perform it, and interest in pursuing further training.

Methods: The training model was designed using CAD/CAM technology. Dental students from the first to fourth year performed the procedure on the 3D-printed models, evaluating their effectiveness. Participants completed an anonymous survey before and after a lecture, rating their knowledge, confidence, and interest in the apicoectomy procedure. They then engaged in hands-on training. A final survey was taken to assess the same criteria.

Results: Model is finalized and functional. Final stages of training are being conducted now. However, initial assessment by students of the new model show high acceptance of the model with significant reports of improvements in participants’ knowledge, confidence and interest by the trained students.

Conclusion – The use of cost-effective, 3D-printed apicoectomy models have the potential to significantly enhance dental students' knowledge, confidence, and interest in the procedure. These models represent a valuable tool for improving surgical training in endodontics, especially for students with limited access to expensive typodonts. Future research should further explore effectiveness for residents.
