Deep margin elevation has become a popular technique for restoring tooth defects with a proximal cavity margin located beneath gingival tissues. With advances in materials technology and the prevalence of minimally invasive methods, less invasive, less time-consuming and less complicated restorations have become feasible. However, a clear definition or a standard operating method on deep margin elevation and sufficient in vitro studies or in vivo randomised controlled trials have yet to be performed to verify the scientificity and reliability of this technique. This article aims to retrospectively evaluate deep margin elevation.

Key words: deep margin elevation, adhesive restoration, tooth defect
