Densely sintered alumina- and zirconia-based restorations were introduced to dentistry in the early 1990s and became a popular treatment modality, especially in situations requiring complete-coverage restorations. The use of industrial technologies for the fabrication of the restoration, simple clinical management, and pleasing esthetic outcome have made these restorations an attractive treatment alternative. This article reviews the nature of the materials used and the technologies involved and provides indications for clinical case selection and tooth preparation.
