Abstract: Subgingival dental defects are mainly caused by crown fracture and caries. Traditional restoration methods have poor prognosis due to many limitations. With the development of digital technology, adhesive materials, and the concept of minimally invasive restoration, deep margin elevation (DME), as a minimally invasive method for restoring subgingival tooth defects, has got more attention by prosthodontists for its high efficiency and convenience. To introduce the effect of DME on periodontal tissue, this review summarizes the research progress of material selection, postoperative marginal integrity, and biological width invasion.

Key words: deep margin elevation, resin materials, marginal integrity, periodontal tissue, biological width
