| Sumario: | Introduction: A subgingivally extending proximal carious defect
can be adequately restored with an adhesive indirect aesthetic
restoration only when the proximal margins can be raised coronal
to the Cementoenamel Junction (CEJ) using various Margin
Elevation Materials (MEM). This approach is commonly referred
to as the Proximal Box Elevation (PBE) technique. However,
there is a lack of evidence in the literature regarding the quality
of the marginal seal at the root dentine- MEM interface when
using PBE technique.
Aim: The purpose of this systematic review was to summarise
the available evidence on the the quality of the marginal seal at
the root dentine- MEM when using the PBE technique during
the placement of adhesive indirect aesthetic restorations.
Materials and Methods: Comprehensive electronic search was
performed in PubMed Central, Cochrane Library and Google
Scholar from their inception to January 2021 at the Department
of Conservative Dentistry and Endodontics, Sri Ramachandra
Institute of Higher Education and Research (SRIHER) between
May 2020 to January 2021. Full text articles published in
english language which have performed an indirect restoration
with and without PBE technique were included in the review.
A total of 249 articles were screened initially in the review. The
main keywords used were: “PBE”, “Cervical Margin Relocation
(CMR)”, “Deep Margin Elevation (DME)” and “coronal margin
relocation”. The review protocol followed the Preferred Reporting
Items for Systematic Reviews and Meta-Analyses (PRISMA)
guidelines. The risk of bias assessment of the included studies
was performed independently.
Results: A total of 9 in-vitro studies were included in the present
systematic review. Resin based composites of different viscosities
seemed to perform adequately as MEM. It may be prudent to
perform the margin elevation in multiple layers. Self etch adhesives
had a better marginal seal than the total etch adhesives. Regarding
the effect of indirect restoration on the marginal seal at the root
dentine- MEM interface, there was no conclusive evidence. PBE
may provide a congenial environment for predictable and efficient
bonding of indirect adhesive aesthetic restorations.
Conclusion: Based on the moderate quality of evidence from the
included articles in this systematic review, it can be concluded
that while performing a PBE technique, the quality of marginal
seal at root dentine- MEM interface is satisfactory under in-vitro
conditions. |
