Zirconia Ceramic Tooth Restorations
High-strength all-ceramic systems for posterior crowns and fixed partial dentures (FPDs) have become available for replacing missing teeth. New core materials have been developed and have evolved in the last decade, with yttrium tetragonal zirconia polycrystals (Y-TZP) based materials being the most contemporary. The strength of Y-TZP is attributed to a process known as transformation toughening. With the emphasis on the use of computer-assisted design/computer assisted- manufacturing technology, various production techniques have been developed for enhancing the fabrication of all ceramic restoration. This article reviews the microstructure, properties, development of materials and technologies for Y-TZP based restorative systems.
