3D Printing in Endodontics: Report of Three Clinical Cases with Innovative Approaches

Abstract

3D printing is a process whereby a given material is deposited in successive layers to create a 3D object. In dentistry, this technology involves three steps: digital data acquisition using a scanner and/or CBCT, data processing and design within a software application, and manufacturing through 3D printing. The aim of the present article is to discuss the clinical application of 3D printing in endodontics through the presentation of three specific and original endodontic clinical cases. Innovative approaches were utilized in these cases for the treatment of a calcified root canal, periapical surgery, and autotransplantation. The results of all three cases were promising regarding proper case selection and in the design process. 3D-printing technology may be helpful to reduce surgical time, operator bias, and the risk of procedural errors.
