The objectives of this study are to determine the clinical performance of zirconia-based dental prostheses and their related properties.
Zirconia has been used in dentistry since 2000 for constructing fixed partial denture. Its advantages are high fracture resistance, excellent biocompatibility, moderate opacity, etc. Because the increase in demand for more esthetic restoration, zirconia becomes more popular for use as a core material for all-ceramic systems. Its properties have been investigated extensively in many in vitro studies. However, clinical performance of zirconia-based restorations would require a period of time before the results can be assessed. Currently, there are not much results regarding clinical performance of zirconia-based prosthesis and more information are required for future research.

Crown-root fracture is one of the most challenging fracture types in the dental traumatology literature. Traumatized anterior teeth require quick functional and esthetic repair. In the case of a compl...
Occlusal wear of the surfaces of restorations and surface wear of dentures.
A prosthesis or restoration placed for a limited period, from several days to several months, which is designed to seal the tooth and maintain its position until a permanent restoration (DENTAL RESTORATION, PERMANENT) will replace it. (From Jablonski, Dictionary of Dentistry, 1992)
A type of porcelain used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Dental porcelain is produced by mixing ceramic powder (a mixture of quartz, kaolin, pigments, opacifiers, a suitable flux, and other substances) with distilled water. (From Jablonski's Dictionary of Dentistry, 1992)
The process of repairing broken or worn parts of a PERMANENT DENTAL RESTORATION.
Inability or inadequacy of a dental restoration or prosthesis to perform as expected.
Dentistry is the study, management and treatment of diseases and conditions affecting the mouth, jaw, teeth and their supporting tissues (Oxford Medical Dictionary) The work of a dentist ranges from regular patient check-up to orthodontics and surgery....
