Elevación de margen profundo, previo a restauraciones definitivas.

Objective: The main objective of this review was to analyze the marginal integrity, microleakage and periodontal status of materials used for deep margin elevation (DME). Material and Method: Two independent reviewers conducted an electronic search of several databases including Scopus PubMed, Embase and Web of Science up to July 11, 2023. This review followed PRISMA guidelines and searched for in vitro studies and human clinical studies. that use DME and report marginal adaptation, microleakage or periodontal status. 692 studies were identified, discarding duplicates using Mendeley, studies that were selected by title and abstract after obtaining the full texts and the evaluation of the risk of bias was carried out using the Cochrane RoB 2.0 tool. Results: A total of 19 in vitro studies and 4 clinical studies were included in the present systematic review. Address proximal caries lesions in posterior teeth with margins under the gums in which the DME technique is highlighted as an option to improve the adaptation and periodontal health of the surrounding tissues. Various materials used in DME are discussed, but a lack of consensus regarding the choice of material and technique persists. Controversy is observed in studies that evaluate the influence of DME on marginal adaptation and microleakage. In addition, the importance of maintaining an adequate distance between the restoration margin and the bone crest to avoid periodontal problems is mentioned. Conclusion: DME shows good adaptation in laboratory conditions and can be useful in situations of limited access under the gums. The reaction of periodontal tissues to DME is still unclear, therefore the impact of DME on the periodontium remains inconclusive.
