Interventions

Type	Name	Description
DEVICE	Lithium disilicate crowns	The study population is separated in two groups. The teeth will be etched in total etch mode with 37% phosphoric acid (Total Etch, Ivoclar Vivadent AG). After the application of Adhese Universal-adhesive (Ivoclar Vivadent AG), MultiCore Flow (Ivoclar Vivadent AG) will be applied. The crowns will be polished, then etched with IPS Ceramic Etching Gel (Ivoclar Vivadent AG) and conditioned with Monobond Plus (Ivoclar Vivadent AG). The crowns will be luted as described for group 1 or 2. A final intraoral polishing step will be done with OptraGloss (Ivoclar Vivadent AG). All required light-curing steps are conducted with Bluephase G4 (Ivoclar Vivadent AG).
