Background:
Teaching 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 & Methods:
Ninety-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.
Results:
Compared 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).
Conclusion:
The 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.
