Localized subgingival margins can complicate the use of indirect adhesive restorations (isolation, impression taking, and delivery) and subsequently hinder their durability and relationship with the periodontal tissues. This article proposes a technique involving placement of a modified Tofflemire matrix followed by immediate dentin sealing and coronal elevation of the deep margin to a supra­gingival position using a direct bonded composite resin base. The deep margin elevation technique may be a useful noninvasive alternative to surgical crown lengthening. This technique may also facilitate the placement of large direct composite resin restorations. The fundamental principles of deep margin elevation are presented. (Am J Esthet Dent 2012;2:86–96.)
