Surface Conditioning Effectiveness, Accuracy and Treatment Result of Zirconia Laminate Veneer

This study aims to evaluate the clinical performance of the zirconia laminate veneer, a minimally invasive prosthetic restoration

Study Overview

Detailed Description

Patients with indications for single tooth restoration with ceramic laminate veneers are recruited for the study. These indications include spaced, discolored, malformed, root canal-treated, chipped, and mildly crowded teeth. After providing written informed consent, all patients are randomly divided into two groups in a double-blind manner (participants and the outcomes assessor) in a 1:1 ratio, including the Zirconia group (intervention) and the Lithium Disilicate group (control). Each patient's tooth is prepared and restored with the corresponding laminate veneer material, that is, zirconia and lithium disilicate.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Zirconia laminate veneer

Intervention: Single-tooth restoration using zirconia ceramic laminate veneers.

Procedure:

Tooth preparation following standard protocols for laminate veneer placement. Fabrication of zirconia laminate veneers. Cementation of zirconia laminate veneers with appropriate bonding protocol. Follow-Up: after 2 weeks, 6 months, and 12 months

Zirconia veneers are milled with computer-aided manufacturing technology from multilayered zirconia discs with shade matched with adjacent teeth. After sintering, veneer surfaces are treated with a hydrofluoric acid-nitric acid mixture. Next, veneers are cut back if necessary to provide space for characterization. Veneers are bonded with a light-cured veneer adhesive system (Relyx Veneer LC, 3M, USA).
Active Comparator: Lithium Disilicate laminate veneer

Intervention: Single-tooth restoration using lithium disilicate ceramic laminate veneers.

Procedure:

Tooth preparation following standard protocols for laminate veneer placement. Fabrication of lithium disilicate laminate veneers. Cementation of lithium disilicate laminate veneers with appropriate bonding protocol.

Follow-Up: after 2 weeks, 6 months, and 12 months

Lithium Disilicate veneers are milled with computer-aided manufacturing technology from lithium disilicate blocks with shade matched with adjacent teeth. After sintering, veneer surfaces are treated with hydrofluoric acid. Next, veneers are cut back if necessary to provide space for characterization. Veneers are bonded with a light-cured veneer adhesive system (Relyx Veneer LC, 3M, USA).
