Objective To evaluate the effects of applying oral virtual patient combined with case-based learning (CBL) in clinical practice teaching of prosthodontics. Methods Five typical cases with common diseases in prosthodontics were selected. The three-dimensional (3D) data were obtained by intraoral scanning and facial scanning, and registered to build 5 virtual patients. Cluster sampling was used. From September 2022 to April 2023, a total of 79 students in eight-year or five-year programs who were taking the clinical practice of prosthodontics in Peking University School and Hospital of Stomatology enrolled in the study, and were divided into two groups according to the practice number, including 39 students in study group and 40 students in control group. Combined with the CBL in the two groups, the study group used 3D images of virtual patients for case learning; while for the control group, intraoral and facial photographs of the same cases were used. Clinical examination and questionnaires were performed to compare the learning effects between the two groups. Non-parametric Mann-Whitney U test was used to analyze the data. Results The total score of clinical examination in study group was higher than that in control group [30.5 (3.5) vs. 27.3 (3.0)], P＜0.001. There were 36 valid questionnaires collected from both the study group and the control group, respectively. The questionnaires showed higher scores in study group than those in control group in terms of “stimulating learning interest and enthusiasm” [100.0% (36/36) vs. 77.8 % (28 /36)], “improving initiative and ability of independent thinking”[100.0% (36/36) vs. 97.2 % (35/36)], “solving problems and clinical thinking” [97.2 % (35/36) vs. 91.7% (33/36)], all P＜0.05. Conclusions The application of virtual patient combined with CBL in clinical practice teaching of prosthodontics can improve the students' score of clinical examination, improve clinical thinking ability and satisfaction.
