Glass-ionomers

• Most commonly referred to as glass ionomer
  cements (GIC's).
• These are materials which consist of an aqueous
  polyacrylate and a fluoroaluminosilicate glass.
• These set by an acid-base reaction in the
  presence of water.
• These cements appear to adhere to tooth
  structure by formation of ionic bonds as a result
  of chelation of the carboxyl groups in the acid
  with the calcium and/or phosphate ions in the
  apatite of enamel and dentin.

The future

• Adhesive dentistry
• Improving the properties of adhesive materials.
  e.g. wear resistance, strength
• Biocompatible materials
• Antibacterial, bioactive, drug delivery
• Increasing use of implants
• Shorter healing periods
• Poorer quality bone
• Less bone
• Growing natural teeth
