Introduction
ATROPHIC
Implant-supported restoration is considered to be highly complex and risky for patients with extensive missing teeth and a severely atrophic anterior maxilla (Learning dental implant therapy at severely atrophic maxilla requires highly creative thinking and the good imagination of the students (Problem-based learning (PBL) and case-based learning (CBL) have been described as effective and acceptable tools for medical and dental education (This study details a PBL-CBL method with a full digital workflow (digital PBL-CBL method), which features vivid 3D presentation of final restoration and tissue contour, measurable tissue contour changes, and accurate correction of contour discrepancies using digital tools. The aim of this study is to evaluate the effectiveness of the digital PBL-CBL method in teaching complex implant cases at atrophic anterior maxilla.
