Risk Factors with Porcelain Laminate Veneers Experienced during Cementation: A Review

Abstract

The clinical success of porcelain laminate veneers (PLVs) depends on many clinical and technical factors, from planning to execution, among which adhesive cementation is of significant importance. This procedure carries many risk factors if not optimally executed. The objective of this study was to document the clinical parameters affecting successful cementation procedures with a focus on the adhesive strength, integrity, and esthetics of the PLVs. A literature search was conducted through MEDLINE, complemented by a hand search using predefined keywords. Articles published in English between 1995 and 2023 were selected. According to this review, the success and longevity of PLVs rely in great part on the implementation of a precise cementation technique, starting from field isolation, adequate materials selection for adhesion, proper manipulation of the materials, the seating of the veneers, polymerization, and elimination of the excess cement. Several clinical steps performed before cementation, including treatment planning, preparation, impression, and adequate choice of the restorative material, could affect the quality of cementation. Scientific evidence suggests careful implementation of this process to achieve predictable outcomes with PLVs. The short- and long-term clinical success of adhesively luted PLVs is tributary to a deep understanding of the materials used and the implementation of clinical protocols. It is also contingent upon all the previous steps from case selection, treatment planning, and execution until and after the cementation.

Clinical outcomes of self-glazed zirconia veneers produced by 3D gel deposition: a retrospective study

“…The color and translucency of veneers were matched to adjacent teeth during tried-in, however, they looked yellowish after cementation. It could be ascribed to the color exposure of cement [ 41 ]. The color change effect of resin cement increases when the ceramic thickness decreases, especially for the high-translucent veneers [ 42 ].…”

Conventional Versus Minimally Invasive Veneers: A Systematic Review

“…The joining of a veneer with dentin that has increased pliability under the gravitational pull of loading may result in increased stress concentrations, creating an ideal environment for the emergence of fracture propensities [ 26 ]. Veneers, on the other hand, are positioned to navigate the contours of load-induced stress with more resilience and buoyancy when they are entrenched upon the bedrock of enamel’s unyielding embrace [ 27 - 29 ].…”

Fabrication of glass/madar fibers reinforced hybrid epoxy composite: a comprehensive study on the material stability

“…At the same time, they also take advantage of the renewable and lightweight characteristics offered by natural fibers like flax, jute, or hemp. The combination of these factors leads to the development of composites that exhibit a commendable equilibrium in terms of strength, weight, and environmental conscientiousness 5 . Hybrid composites are extensively utilized in several industries, including automobile components, athletic goods, and construction materials, due to their commendable amalgamation of performance attributes and environmental sustainability, which are much esteemed 6 .…”
