Novel glass-ceramics for dental restorations.

BACKGROUND
There are many different ceramic systems available on the market for dental restorations. Glass-ceramics are a popular choice due to their excellent esthetics and ability to bond to tooth structure allowing a more conservative approach. However, at present, these materials have insufficient strength to be used reliably in posterior regions of the mouth.


PURPOSE
The aim of this review article is to discuss the types of novel glass-ceramic currently be investigated including composition, microstructure and properties.


CONCLUSION
Current research in glass-ceramics focuses on the quest for a highly esthetic material along with sufficient strength to enable crowns and bridgework to be reliably placed in these areas.


CLINICAL SIGNIFICANCE
There is a gap in the market for a machinable resin bonded glass-ceramic with sufficient strength as well as excellent esthetics.
