Factors that Influence the Clinical Longevity of Ceramic Unit Restoration: A Scoping Review

Abstract

Statement of Problem: Ceramic restorations can be essential in dental rehabilitation aesthetic and functional, but its longevity and treatment plan need to be good settled down. Different material options, manufacturing techniques and protocols are available. It is important to map the literature to know the state of the art about of clinical failures related to these fixed prostheses.
 Purpose: Evaluate the rate of survival of single restorations (crowns and ceramic veneers) as well as identify the types of clinical complications reported.
 Material and methods: A scoping review was conducted from the MEDLINE/Pubmed, Embase, Scopus, Web of Science and Cochrane Library. A search of all published literature until June 2021 was based on the following keywords: ('dental crown' OR 'ceramic veneer' OR 'porcelain veneer' OR 'dental veneer' OR 'dental porcelain') AND ('survival rate' OR 'ceramic restoration failure' OR 'prosthesis complication' OR complication).
 Results: The most reported biological complications were need for treatment endodontic and detachment. The complications and technical failures involved, mainly, fractures and cracks in ceramics. There were also cases of pigmentation marginal.
 Conclusion: The survival rate of single ceramic restorations is high. The main factors influencing restoration failures are bruxism, operator inexperience and inadequate cementation.
