Deep Margin Elevation is a useful tool when sub gingival interdental margins are encountered in indirect adhesive restorations. Subgingival margins, of coarse, can complicate the use of adhesives and composites due to the inability to maintain the proper environment. Isolation, impression taking, and delivery are subsequently hindered, leading to a poor prognosis of the restoration.The margins on these restorations also have poor durability and their relationship with the periodontal tissues can lead to increased inflammation and possible bone loss. 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. Dr. Magne outlines the procedure and Dr Matt Nejad performs a clinical case which can be found in those links. They are both a very interesting read and are worth your time.
