Abstract
Background: Partial laminate veneers (PLV) have been accepted widely among both clinicians and patients with their favorable specifications, such as conservativeness, superior esthetics, bond strength and durability, for three decades. Various esthetic and functional impairments spreading in a wide range may be restored with veneers instead of full contour crowns. Objective: Although advantages, partial laminate veneers are not free from complications and various factors can influence the service duration of these restorations. Methods: An electronic Pubmed/Medline and Google Academic search was conducted without time restriction, providing information on porcelain laminate veneer’s failure rate and survival. Assessment of the identified studies was performed by two independent reviewers. Clinical service durations and various types of failures were evaluated. Results: Debonding, fracture, discoloration of the porcelain; staining or disintegration of tooth-porcelain margin; hypersensitivity, secondary caries, pulp necrosis and the periodontal responses were the more frequently studied failures. The mean CFR was found as 8,22% per study. Enamel substrate, incisal overlapping and lithium disilicate veneers presented lower failure rates in comparison with dentine substrate, non-overlapping and feldspathic veneers. Conclusion: PLV’s have high survival rates. The overall survival of PLV restorations can be affected by several prognostic variables.
