Outsmarting COVID-19 through rapid 3D printing and flipped learning in fixed prosthodontics

Abstract

This paper describes the transformation of pre-Covid 19 educational practices in Fixed Prosthodontics at the School of Dentistry, University of Pretoria. The sudden need for social distancing limited access to the main preclinical skills laboratory, which was overcome by 3D-printed phantom heads that were rapidly produced by the Central University of Technology. This allowed preclinical training to continue in clinical spaces. The educational philosophy also had to be adjusted because contact time became limited. The traditional lecturer-centered approach followed (lectures, notes, demonstrations, practicals and log books) was transformed to a student-centered approach through the production of high quality audio-visual material that allowed students to prepare for practicals in advance. These materials provided learner support at chairside on computer screens and mobile devices and facilitated self-directed learning. Students were formatively assessed using a chairside computer system with the aim of developing competence. This short communication also discusses the lessons learnt from this innovative project and the change in educational philosophy.
