Application of problem-based learning and case-based learning integrated method in the teaching of maxillary sinus floor augmentation in implant dentistry

Abstract

BackgroundTeaching of maxillary sinus floor augmentation (MSFA) is challenging for dental educators due to the varied sinus anatomy and high rate of complications. The method integrating problem-based learning and case-based learning (PBL-CBL method) may be more effective than the traditional teacher-centered method. The aim is to evaluate the efficacy of the PBL-CBL method in teaching MSFA.Materials & MethodsNinety-two students who received training between 2015 and 2017 at the Department of Implant Dentistry were divided randomly into an experimental group and a control group. Students in the experimental group were trained using the PBL-CBL method, while those in the control group were trained using the traditional teacher-centered method. After three months of training, a survey of the students’ opinions about the corresponding teaching method was carried out through a feedback questionnaire. A theory test was used to investigate the level of MSFA knowledge among the students. A case analysis was designed to test whether the students can apply the knowledge in solving new problems.ResultsCompared with the control method, the PBL-CBL method resulted in higher scores in both the theory test and the case analysis, and obtained a higher rate of satisfaction among the students. The difference in scores between the two methods were statistically significant (P < 0.01),ConclusionThe PBL-CBL method resulted in better results regarding acquisition of academic knowledge, ability in case analysis and student satisfaction compared with the teacher-centered method. It may be a promising mode for teaching complex surgical techniques in implant dentistry and other dental fields.
