(TC21) Integration of Digital Dentistry in Endodontics to Create Transparent Resin Tooth Models Displaying Root Canal Systems

Abstract: The visualization of the intricate root canal system within a tooth is crucial for endodontic education, training, and treatment planning. This project explores the fusion of digital scanning and 3D printing technology to create transparent resin tooth models that accurately represent the internal root canal anatomy. The objective of this study is to demonstrate the feasibility of producing highly detailed, clear resin models for enhanced endodontic visualization and education. High-resolution cone beam computed tomography (CBCT) scans of human teeth were acquired, along with scans from intraoral scanners. AI image processing techniques were applied to enhance the quality of the scans, including noise reduction, segmentation of the root canal system, and image reconstruction to generate precise 3D models. Utilizing computer-aided design (CAD) software, transparent resin tooth models were designed to incorporate the 3D root canal anatomy. The models were then 3D printed using a high-resolution 3D printer. This project successfully demonstrates the importance and benefit of digital dentistry in endodontics. Via scanning and printing, transparent resin tooth models that accurately portray the intricate root canal system were printed. These models have the potential to revolutionize endodontic education and treatment planning, offering a tangible, 3D visual aid of any given tooth, which enhances comprehension and communication. By combining cutting-edge technologies, we can further advance the field of endodontics, fostering better patient outcomes and expanding the knowledge base of dental professionals. This innovation represents a significant step toward more effective and sustainable dental education and practice.
