About

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

Full 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.

Enrollment: 50 estimated patients

Sex: All

Ages: 18 to 90 years old

Volunteers: No Healthy Volunteers
