Assessment of a virtual prosthetic case planning environment for dental education - A multicentric analysis

Objectives: The aim of the present study was the multicentric assessment of the virtual prosthetic case planning environment (VCPE), which relocates patient planning into the virtual space in dental education. Materials and Methods: The VCPE is separated into two rooms: a virtual entry area where the user can choose between 10 different prosthetic case plans of ascending complexity, and a virtual patient case planning room. In spring term 2022, the use of virtual case planning was voluntarily assessed in four different German dental schools (DSs) from the perspective of both lecturers and students. The assessment was performed afterwards using a questionnaire. Data were analysed using Kolmogorov-Smirnov test, exploratory data analysis, Fisher-Freeman- Halton test, and exact Fisher test. Reliability was assessed with Cronbach Alpha test (a < 0.05). Results: A total of 59 lecturers and 63 students were included. There were 38.5% male, 60.7% female, and 0.8% diverse participants. The mean age of the lecturers was 36.2 +/- 9.0 years and of the students 24.3 +/- 3.0 years. The VCPE was assessed as good, yet the evaluations between either the DSs or between the lecturers and students were significantly different. Conclusions: Even though for some assessment criteria significantly different results between the four DS were observed, the majority of participants evaluated the VCPE positively and recommended them for teaching. The virtual reality as a teaching method for teaching prosthetic case planning for the further preparation of the students for the later professional life can be considered as helpful.
