Coronally Moving Sub-Gingival Margins: An Approach for Better Restorations- A Narrative Review

Deep proximal carious lesions with subgingival margins present a significant restorative challenge due to compromised isolation, difficulty in achieving marginal integrity, and risk of supra-crestal attachment violation. These techniques have emerged as a conservative substitute of invasive surgeries by relocating the deep sub-gingival margins to a supragingival position with the help of adhesive restorative materials. Current evidence suggests that, when appropriately indicated and executed, DME facilitates improved marginal adaptation, preservation of periodontal health, and successful restoration of teeth with deep subgingival margins. This represents a minimally invasive and clinically effective approach in contemporary restorative dentistry.
