3D-printed model for hands-on training in dental traumatology

Aim To assess the feasibility of creating a realistic model for hands-on training in dental traumatology using 3D printing technology, and then to investigate the added value of working with the website dentaltraumaguide.org. Methodology With the use of special software applications, a model was designed based on the CBCT of the maxilla of a real patient that imitated several traumatic dental injuries. The model was reproduced using a stereolithographic printer to use the specimens in a hands-on training course on dental traumatology for undergraduate students in their final year in the Department of Conservative Dentistry and Periodontology in Munich, Germany. During the course, half of the participants had access to dentaltraumaguide.org, whereas the others did not. The students were then assessed according to their theoretical knowledge and practical performance in simulated treatment. These data were analysed by Kolmogorov-Smirnov test, unpaired t-test and Mann-Whitney U test. Subsequently, the participants were asked to evaluate the model. Results The workflow for manufacturing a model of dental traumatology for training purposes was practical and relatively inexpensive. In the evaluation process, the model was considered to be highly realistic and useful during an instructive hands-on training course. There were significant differences between the two groups in favour of using the dentaltraumaguide.org website. Conclusions 3D printing technology offers new possibilities for training specific dental treatments that are currently difficult to imitate. The online platform dentaltraumaguide.org assisted students in correctly managing traumatic dental injuries.
