What is the most appropriate cement for bonding an all-ceramic crown?

Resin cement (dual-cure or light-cure adhesive resin cement) is the material of choice for cementing all-ceramic restorations because it bonds adhesively to the etched ceramic surface (via silane coupling agent) and to conditioned tooth structure. This bonding provides support to the ceramic, increasing fracture resistance. Additionally, resin cements are available in a range of shades (translucent, white, etc.) that can be chosen to optimize the final esthetic result. Glass ionomer and zinc phosphate cements are not suitable for all-ceramic crowns as they do not provide adequate adhesion to ceramic.
