title: 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.
  
  
  OBJECTIVE
  The aim of this review article is to discuss the types of novel glass-ceramic currently be investigated including composition, microstructure and properties.
  
  
  CONCLUSIONS
  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.
  
  
  CONCLUSIONS
  There is a gap in the market for a machinable resin bonded glass-ceramic with sufficient strength as well as excellent esthetics.
