Abstract :
Biocompatible materials used for the fabrication of dental crowns were studied. Patients were treated with Gold, Porcelain and Zirconia crowns. Dental crowns were selected according to patient’s clinical status and needs. We found that Gold crowns had low patient acceptance because of poor aesthetics and high cost. Gold crowns could not be used opposite to amalgam restorations for the fear of galvanic shock. Porcelain crowns were extremely aesthetic and did not cause galvanic shock. Porcelain crowns however could not be used in patients with habitual clenching of teeth condition called as Bruxism. Zirconia was found to be the most aesthetic and the most biocompatible with high mechanical strength.
