Sammanfattning
Yttrium oxide stabilized tetragonal zirconiumdioxide polycrystal (referred to as yttria-stabilized zirconia, Y-TZP or briefly zirconia) is a durable dental ceramic material that has exceptional biocompatibility. These properties make it an excellent material for use in the oral cavity. Zirconia was first introduced as a framework material (first generation) for tooth-supported single crowns and fixed dental prostheses (FDPs). The survival rates of these constructions are high, and the only drawback has been the exposition to superficial porcelain chipping, so called chip-off fractures. This lead the learning curve in veneering techniques, as well as development of new more translucent zirconia materials that could be used as monolithic structures without veneering porcelain or cut-back structures where only the labial facades are veneered. The purpose of this article is to highlight the material properties of different zirconia materials, as well as to provide some clinical indications
