Porcelain Laminate Veneers: Clinical Longevity, Determinants of Success, and Sustainable Minimally Invasive Dentistry—A Narrative Review

Background: Porcelain laminate veneers (PLVs) are adhesively bonded, partial-coverage ceramic restorations widely used for anterior esthetic rehabilitation. Although long-term clinical performance is generally favorable, outcomes vary with bonding substrate (enamel vs dentin), preparation design, occlusal risk, ceramic selection, and cementation protocol. Aim: To narratively synthesize PubMed-indexed evidence on PLV longevity, complication patterns, and clinically modifiable determinants of success, and to contextualize findings within a sustainability lens aligned to the SDGs. Materials and Methods: A narrative review with a structured PubMed/MEDLINE search was conducted using terms related to ceramic/porcelain laminate veneers, survival/success, failure modes (fracture, debonding, marginal discoloration), substrates, preparation designs (including incisal coverage), bruxism/parafunction, and cementation variables. Systematic reviews/metaanalyses, long-term clinical cohorts, and clinically relevant in vitro studies were included. Outcomes were interpreted using standardized functional, biological, and esthetic domains consistent with FDI evaluation criteria for indirect restorations.
