Materials for Direct Restorations

Key Points: 

  • Direct dental restorative materials can be placed directly into a tooth cavity within one office visit.
  • Amalgam remains the gold standard for durable restorations, although resin composites have shown reasonably long survival rates.
  • Many direct restorative materials are also used as cavity liners and bases, and as pit-and-fissure preventive sealants.
