The introducing of zirconia in dentistry has generated considerable interest, which has manifested itself in strong industrial, clinical and research activity. The technology contributes to the fabrication of novel "all-ceramic" zirconia-based restorations with improved physical properties and biocompatible for a wide range of promising clinical applications. Especially with the development of computer-aided design and assisted manufacturing systems, we now have a multitude of zirconia-based materials, each of which has a different microstructure and properties, making it possible to diversify their indications. This is how zirconia has amply deserved its place in prosthetic and implant restorations.
