 | Zirconia ceramic for dental applicationsEngineers at Renishaw are constantly researching dental materials and manufacturing techniques to ensure that you receive the most state-of-the-art frameworks on the market.
All incise dental CAD/CAM frameworks are made from partially-sintered zirconia. Unlike any other ceramic, zirconia has a unique transformation toughening mechanism; when a crack starts to form, its growth is impeded by a phase change in the material. This makes it the ideal choice for dental applications. Material strength of zirconia
Alumina proves to be the most brittle material, shown by the length of the crack formations. Zirconia is the strongest and toughest of all materials tested. incise zirconia provides an optimal combination of strength and low thermal conductivity, whilst also being less hard and therefore more workable than alumina:

Little is known about the nature of the bond between zirconia and porcelain. Incise zirconia has been tested with a number of different porcelains to ensure the delamination forces exceed clinical requirements.
