Técnicas de elevación del margen gingival profundo. Revisión de la literatura.

Abstract

ntroduction: Deep margin elevation (DME) is repositioning sub-gingival margins into supra-gingival margins technique, where various restorative materials are applied to increase marginal integrity and bond strength. Objective: This literature review aimed to identify the techniques used in deep margin elevation. Materials and method: This research followed the PRISMA (Presentation of Systematic Reviews and Meta-analysis) guidelines. A total of 100 articles were collected from various databases: Pubmed (40 articles), Medigraphic (40 articles), SciELO (20 articles), Elsevier (10 articles), and Redalyc (10 articles). When reviewing them, ten were removed for being repeated and 20 for not meeting the eligibility criteria. Of the remaining 70, 30 were discarded for not meeting the inclusion criteria according to PRISMA, resulting in 40 articles and two books that provided information to develop this research. Results: DME is an advantageous technique for repositioning the supra- and sub-gingival margins and achieving adequate tooth restorations. Conclusions: The deep margin elevation technique is highly relevant in restorative processes, replacing the coronal lengthening technique and allowing a less invasive treatment by raising the sub-gingival margin coronally between 2 to 3 mm above the alveolar ridge.
