Causes of failure in laminates: a literature review

Abstract

Laminates are a covering of the buccal face of dental enamel by a restorative material, strongly adhered to the dental element through recent advances in adhesive systems. Laminates have excellent aesthetic characteristics, but their use requires attention so that there are no flaws. The objective of this work is to investigate, through a literature review, the main causes of failures that occur in ceramic laminates, in order to minimize the number of failures. To carry out the study, original articles on the subject were selected in journals listed in the PubMed source (United States National Library of Medicine/National Institute of Health). It is concluded that laminates, when correctly indicated, are a safe and predictable restorative modality. However, it must be emphasized that proper planning and the use of the technique performed by the dentist are essential for the success of the treatment, avoiding possible failures, such as adhesion failures and failures related to the choice of cementitious, resulting in cracks, changes in spots and even fractures.
