Application of 3D‐printed teeth models in teaching dentistry students: A scoping review

Both regular teaching of dentistry students and various training schemes for dentists primarily make use of the series teeth models, resin blocks or extracted teeth, whereas the 3D teeth models may well offer an alternative in this respect.PubMed and EMBASE were searched in September 2020. Eligibility of the studies was determined on whether they had made use of the 3D-printed teeth models in both pre- and post-graduate education in dentistry.The final review embraced 15 studies. There were 659 (89.54%) student participants, and 77 (10.46%) dentists involved in those studies. Five studies addressed the prosthetic and surgical procedures, two-endodontics, one-paediatric dentistry and one-trauma management. The 3D-printed models were also used in the study focused on enhancing the students' manual dexterity, whilst making use of the PhantHome tool.The 3D-printed teeth models developed for teaching purposes are used in various areas of dentistry. Their overall usefulness in acquiring the necessary hands-on skills for clinical work was acknowledged in all the studies under review, regardless of a specific procedure at issue. The 3D models effectively eliminate the hazard of cross-infection. Overall effectiveness of the soft tissue reproduction appears to be their weakest point indicated to date, especially in the surgical models.The 3D-printed teeth models provide an alternative to the extracted ones, and the series teeth models in regular teaching practice. Participants of the studies under review thoroughly recommend introducing 3D models into any hands-on practice.
