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.
Conditions
- Dislocation, Tooth
- Teeth, Endodontically-Treated
- Tooth Fracture
- Tooth Injuries
- Tooth Abnormalities
- Cracked Tooth Syndrome
- Tooth Crowding
Interventions
| Type | Name | Description |
|---|---|---|
| DEVICE | Zirconia laminate veneer | 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). |
| DEVICE | Lithium Disilicate laminate veneer | 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). |
