Abstract
Due to an increasing interest in esthetics and concerns about toxic and allergic reactions to certain alloys,
zirconia was proposed as a new ceramic material in the later part of 20th century. It has become a popular alternative to
alumina as biomaterial and is being used in dental applications for fabricating endodontic posts, crown and bridge
restorations and implant abutments. It has also been applied for the fabrication of esthetic orthodontic brackets. This
article presents a brief history, dental applications and new methods for fabrication of zirconia improving its mechanical
properties. Additionally, the bonding between zirconia and resin cements as well as conventional cementation has been
discussed. The methods of the improvement of the bonding strength have also been highlighted.
Keywords: : Zirconia, dentistry, alumina-zirconia nanocomposites, CAD/CAM, functionally graded concept, interfacial
adhesive.
