3D printed teeth in endodontics: Why, How, Problems and Future. A new Protocol for Micro-CT studies

Abstract

3D printed teeth have the potencial to establish a new standard in endodontic ex vivo studies and endodontic training, potentially supplanting natural teeth. This thesis aimed to identify and try to solve problems that 3D printed teeth in endodontics still present. The primary aims were (1) to evaluate the impact of support material of a commercial tooth replica, on the preparation technique and its potential effects on the volume increase evaluation using micro-CT scans and, (2) to develop and validate a protocol for complete removing support material from 3D printed teeth and assessing its efficacy by comparing the internal anatomy of a natural tooth with 3D printed teeth using micro-CT.
