In recent twenty years, the physical and mechanical properties and the operation process of dental ceramic materials have gotten a huge development. All-ceramic restorations have good esthetics and biocompatibility, so they are replacing porcelain fused metal restoration gradually. Technology of digital all-ceramic restorations use computer aided design and computer aided manufacture（CAD/CAM） to manufacture all-ceramic restorations. At present, a lot of all-ceramic restorations are completed by digital technology which is a hot spot in recent researches and clinical applications. This article will summary and prospect of digital all-ceramic restorations by necessity of digital all-ceramic restorations, CAD/CAM, design and manufacture of restoration, material selection, all-ceramic bonding techniques.
