Clinical performance of indirect restorations with cervical margin relocation in posterior teeth: A systematic review

Abstract

Purpose: The purpose of this systematic review was to evaluate the clinical performance of indirect restorations with cervical margin relocation (CMR). Study selection: An electronic search was undertaken in March 2021 using three data bases; PubMed, Scopus, and Web of science. Eligibility criteria included clinical studies reporting clinical series of patients rehabilitated with indirect restorations with CMR in posterior teeth, with a minimum follow-up of one year. Results: a total of six articles were included for a qualitative analysis of this review, in which 250 posterior teeth were treated with indirect restoration following CMR. The follow-up time described in all the studies varied between one and seventeen years. Most of the studies included did not report any complications when elevating the margins using direct fillings prior to the definitive indirect restorations. Meanwhile, the remaining studies revealed few complications such as increased bleeding while probing, partial discoloration, and irregularity in a few teeth where CMR was performed. Conclusions: CMR procedures prior to indirect restorations could be associated with low rate of complications in a relatively long term. However, there is a need for randomized controlled clinical trials to evaluate the long-term longevity and clinical performance of teeth restored with marginal elevation procedures.
