Abstract:

Deep proximal lesions with significant defects and subgingival margins exceeding cementoenamel junction are common clinical scenarios. With the development of materials and bonding dentistry, along with the popularization of the concept of minimally invasive dentistry, deep margin elevation is becoming an option for its minimal invasion and less time-consuming. Even though deep margin elevation seems a valuable technique, clinicians have not extensively applied it limited to its technical sensitivity. Current research is mainly in vitro and lacks high-quality clinical randomized controlled trails, or even standardized clinical process. This review summarizes the concept, procedure and clinical performance of deep margin elevation.

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