Background: Post-endodontic restoration with deep subgingival marginsbeyond the cementoenamel junction (CEJ) is a challenge in itself. This
condition can cause difficulties in insulation with rubber dams, molding, and
restoration cementing. The subgingival margin is also at risk of triggering
gingival inflammation and invasion of biological width (BW) due to its proximity
to the alveolar bone. Surgical crown lengthening (CL) is often recommended to
restore the ideal distance of the BW, but the procedure is invasive. As a more
conservative alternative, Deep Margin Elevation (DME) allows elevation of the
subgingival to supragingiva margin to improve the integrity of the restoration
without invading the BW.
Case report: The first case on the interproximal teeth 24 and 25 (Bone
Sounding: 1mm) was performed CL by the Periodontics department prior to
crown preparation, after previously undergoing endodontic and post fiber
treatment in the Dental Conservation department. The second case was in 36
previously treated teeth (Bone Sounding: 2mm) with deep subgingival margins,
DME was performed using a high-filler composite resin prior to onlay
restoration. Both procedures were carried out at RSKGM FKG UI.
Conclusion: Proper indication for CL and DME at the deep subgingival margin
can improve the optimization of periodontal health and the integrity of postendodontic restoration.
