Study Overview
Brief Summary
This study aims to evaluate the clinical performance of the zirconia laminate veneer, a minimally invasive prosthetic restoration
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.
