Study Summary
This investigation will be a longitudinal clinical trial to study the long-term clinical performance of a resin cement for chairside CAD/CAM restorations. Lithium disilicate chairside CAD/CAM onlays will be adhesively bonded using a selective enamel etch technique with an adhesive. Full contour zirconia crowns will be cemented using a self-adhesive resin cement.
Primary Outcome
Retention. Evaluations according to FDI World Dental Federation criteria (Hickel et al., 2010) \[5b.1 Restoration in place; 5b.5 Complete loss of restoration\] Functional property (retention) assessed by visual and/or tactile assessment by two independent examiners.\]
Interventions
- DEVICE Lithium disilicate onlays (IPS emaxCAD/Ivoclar)
- DEVICE Chairside zirconia crowns (3M)
