SP-9 Applications of 3D Printing Technology in Endodontics
CE Hours: 1.0
Description: Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies provide new possibilities for diagnosis, treatment planning and student education in dentistry. Applications of three-dimensional (3D) printing technology to dentistry have dramatically changed the disciplines of orthodontics, prosthodontics, oral and maxillofacial surgery, and more recently Endodontics. Fused deposition modeling (FDM), Digital light processing (DLP) and stereolithography (SLA) are available for use to print. Cone beam computed tomography (CBCT) and 3D oral scans have been used in Endodontics as the imaging modality of choice for treatment planning of nonsurgical and surgical endodontic approaches. The application of 3D printing in endodontics was investigated in 3 modalities: guided non-surgical endodontics (guided endodontic access), guided surgical root resection endodontics (surgical guides, diagnosis, and treatment planning), and educational models in clinical simulation (preclinical training). The presentation will describe endodontic treatments performed with the aid of CBCT imaging and oral scan data used in 3D printing guides for endodontic access and surgical endodontics. The use of this data to develop endodontic preclinical training models is a highlight of the presentation.
Learning Objectives:
- List the current 3D printing technologies available for endodontic treatments.
- Describe the applications of 3D printing technologies for endodontic treatments and education.
- Apply 3D printing technologies for patients and students in the discipline.

Dr. Katsushi Okazaki currently serves as Clinical Assistant Professor in the Department of Endodontics at New York University College of Dentistry, USA, and concurrently holds a position as Clinical Associate Professor in the Department of Endodontics at Tokyo Dental College, Japan. After earning his D.D.S. and master's degree in dentistry from Aichi Gakuin University School of Dentistry (1987), Dr. Okazaki obtained a Ph.D. in Anatomy and Physiology from Aichi Medical University. He conducted postdoctoral research at the University of Minnesota's Department of Development and Surgical Sciences before completing his specialty training in Endodontics at New York University College of Dentistry in 2012.Dr. Okazaki has made notable scholarly contributions to the field as a co-author of a chapter in the seventh edition of Ingle's Endodontics (Wiley-Blackwell) and as the primary author of a chapter in Endodontic Prognosis: Clinical Guide for Optimal Treatment Outcome (Springer). His excellence in clinical education and research has been recognized by New York University with the Distinguished Educators Award (2015) and the Research Award (2018).His current work focuses on the application of Augmented Reality (AR) and Extended Reality (XR) in endodontic practice and education. He has presented pioneering research at the American Association of Endodontists Annual Meetings in 2021, 2023, and 2024, and published influential papers on these technologies in 2024 and 2025. Dr. Okazaki leads international collaborative projects between Melbourne University, the Institute of Science Tokyo, and Tokyo Dental College, with outcomes to be presented at World Expo 2025 Osaka. He also serves as a Key Opinion Leader for Laschal, a leading U.S. surgical instrument manufacturer, advancing global endodontic practice and education.
