Resumo de Recurso

GLASS IONOMER
  1. Contains fluoroaluminosilicate (fluoride releasing)
    1. Adheres directly to enamel and dentine
      1. Cariostatic properties from fluoride release
        1. Brittle and poor resistance to abrasion
        2. ADVANTAGES OF USING GI
          1. Tooth coloured and translucent
            1. Bonds directly to enamel and dentine no adhesion system required
              1. Easy to mix and manipulate
                1. Fluoride release
                  1. Can be resin modified to increase strength
                  2. DISADVANTAGES OF USING GI
                    1. Wear resistance and compressive strength less than composite
                      1. poor aesthetics for ant teeth
                        1. Finite working time - sets fast
                        2. CLINICAL INDICATIONS FOR USING GI
                          1. Abrasion and erosion cavities

                                  2. CONTRAINDICATIONS OF USING GI
                                    1. Class I, Class II - wear resistance and strength probs
                                      1. Class III, IV unless no alternative
