Narrative Review of Lithium Disilicate Veneers in Esthetic Dentistry: Current Perspectives and Clinical Case Report

To provide a focused, evidence-based overview of lithium disilicate (LDS) veneers, with particular emphasis on indications, material properties, adhesive protocols, and clinical performance, supported by illustrative clinical cases.

A narrative review of the literature was conducted to summarize current evidence on the mechanical, optical, and adhesive characteristics of LDS ceramics in veneer applications. The review emphasizes enamel preservation, adhesive reliability, and reported clinical outcomes, without undertaking a systematic comparison of study designs. In addition, two clinical case reports are presented to illustrate the clinical workflow for esthetic rehabilitation using pressed LDS veneers.

LDS veneers demonstrate high flexural strength (~360-400 MPa), favorable optical properties, and reliable adhesive performance when enamel is preserved and appropriate adhesive protocols are applied. Reported survival rates exceeding 95% at up to 10 years have been documented in selected patient populations. Clinical success is closely associated with appropriate case selection, conservative tooth preparation, precise adhesive procedures, and patient compliance. Common complications, including debonding, fracture, and marginal discoloration, are more frequently reported when enamel is limited or occlusal risk factors are not adequately managed.

When applied under appropriate clinical conditions, LDS veneers represent a predictable and esthetically effective treatment option in contemporary restorative dentistry. Their long-term success depends on meticulous technique, patient-specific risk assessment, and adherence to evidence-based adhesive and occlusal management principles.
