Synthesis and testing of dental ceramic

Zirconia has been recently introduced in prosthetic dentistry for the fabrication of crowns and fixed partial dentures, in combination with CAD/CAM techniques. Zirconia stabilized with Y2O3 has the best properties for these applications. This project aims at producing cast Zirconia blocks primarily for dental application that is more cost effective and biocompatible in comparison to the commercially available zirconia. A simple coprecipitation method was used to produce the zirconia powder; simple, inexpensive and indigenous method of uniaxial compression was employed to cast the zirconia pellet. Further studies have to be carried out to study and improve the densification behaviour, biocompatibility, aesthetics and resistance to masticatory force.
