Novel glass-ceramics for dental restorations

Abstract

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.
