The digital problem-based learning and case-based learning (PBL-CBL) method enhances satisfaction and knowledge acquisition for teaching complex esthetic implant cases. This digital approach improves clinical problem-solving skills compared to traditional methods.
Area of Science:
- Dental Implantology
- Medical Education
- Digital Dentistry
Background:
- Teaching esthetic implant restoration for atrophic maxilla is complex due to augmentation challenges.
- Traditional problem-based learning and case-based learning (PBL-CBL) methods are enhanced by digital workflows.
- A new digital PBL-CBL method aims to improve the teaching of complex implant cases.
Purpose of the Study:
- To evaluate the effectiveness of a digital PBL-CBL method in teaching complex implant cases in the esthetic zone.
- To compare student satisfaction and performance between digital PBL-CBL, traditional PBL-CBL, and didactic methods.
Main Methods:
- A full digital workflow for dental implant therapy was established.
- Digital case data was used for teaching in the digital PBL-CBL group (n=54 postgraduate students).
- Students were divided into three groups: digital PBL-CBL, traditional PBL-CBL, and a control (didactic).
Main Results:
- The digital PBL-CBL method achieved higher student satisfaction across most items compared to traditional PBL-CBL and didactic methods.
- Case analysis scores were significantly higher in the digital PBL-CBL group than in the traditional PBL-CBL and control groups.
- The digital PBL-CBL group showed significantly improved theory test scores compared to the control group.
Conclusions:
- The digital PBL-CBL method offers higher student satisfaction and better academic knowledge acquisition.
- This method demonstrates improved practical clinical problem-solving abilities for complex implant cases.
- The digital PBL-CBL method is a promising alternative for teaching challenging anterior maxilla implant restorations.
