Deep margin elevation: A handy technique to restore subgingival margins

Date: 17 November 2022 | Time: 16:15-17:00 (GST) | Location: Online Event


Subgingival margins are a very common challenge in day-to-day practice and the Deep Margin Elevation (DME) - or Coronal Margin Relocation (CMR) - is a handy and conservative technique to restore direct and indirect restorations with subgingival margins as it avoids a surgical treatment that involves bone removal. 

It basically consists of adding a base of resin composite over the subgingival margin to relocate it coronally. After placement of a circumferential metal matrix tightly adapted around the tooth, a layer of injectable or paste resin composite is placed to bring the margin higher, aiming to mimic the original emergence profile of the tooth.

This technique gained a lot of visibility with the increasing popularity of CAD/CAM restorations, which require visible margins for intra-oral scanning and can be used to treat several cases involving deep lesions.

However, it’s important to highlight that some important criteria must be strictly followed for a successful outcome of this technique, minimizing periodontal inflammation with predictable long-term survival rates. 

Learning Objectives

The aim of this lecture is to describe the Deep Margin Elevation technique and the scientific evidence supporting this procedure in detail, with its indications and related materials, enabling clinicians to identify the inclusion criteria and apply this technique in their daily practice.
