Dental innovation: a 3D printing of canine teeth to improve endodontic training

Abstract

Introduction. Dentistry has evolved with 3D printing, enabling accurate surgical planning and the creation of three-dimensional dental models for educational and professional practices. This study explores the fabrication of 3D-printed synthetic canine teeth for endodontic practices. Objective. exploring the use of 3D printing for the fabrication of synthetic canine teeth for endodontic practices. Methodology. An experimental study was conducted to evaluate 3D printed artificial teeth compared to real teeth, using Cone beam computed tomography (CBCT) and 3D printing technology. An adult patient with complete and healthy dentition was selected. The teeth were reconstructed with specialized software, and prototypes were printed using photosensitive resin. These prototypes were clinically evaluated; endodontic tests, including canal preparation and obturation, were performed to check their suitability under simulated conditions. Results. The prototypes showed high morphological precision and adequate mechanical resistance, although with some variations in the root canal anatomy. Cavity shaping, conductometry, and chemical-mechanical preparation were effective, although fragility was observed in the apical third. Gutta-percha obturation was successful, concluding the endodontic treatment effectively. Conclusion. 3D-printed canine teeth for endodontics are accurate and customizable, but they have limitations in internal morphology and apical fragility. Their use enhances the educational and clinical experience, requiring further research to optimize results.
