What type of cement do you recommend for cementation of all-ceramic CAD/CAM restorations?

CAD/CAM restorations are usually made from some type of high- strength ceramic. It is best to cement these restorations with a resin cement. Self-adhesive resin cements are easy to use, require no additional bonding agent, and have high strength. A new product in this category is Bifix SE (VOCO America, Inc). It comes with two types of mixing tips and intraoral tips for easy access to the tooth. It has a soft gel phase for easy clean-up and a low film thickness for complete seating of the restoration.
