Glass ionomers l.jpg
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.

    • 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
