India is presently in a state of major shift in demographics towards elderly population.  Increasing age of the society has a direct and amplifying effect on prevalence of edentulousness (state of missing teeth). Dental health must emphasize on providing affordable treatment to the existing edentulous population. Typically, ceramics are used as indirect restorative materials for missing teeth as crowns and bridges.  Biocompatible glass ceramics have been well investigated for biomedical and dental applications.In particular, mica based glass ceramics are of greater scientific interest due to their high machinability and in vitro cytocompatibility. Having tested for their cellular functionality, antimicrobial properties and wear mechanisms, glass ceramics that were developed earlier in the research group of Co- Supervisor were found to have insufficient mechanical properties in terms of hardness and strength for dental restorations. In order to improvise on the present mica glass ceramics, the present project proposal is focused on the development of a novel mica based glass ceramic composites reinforced with zirconia.
