  • Bonding to calcified tissues
    Patent number: 4548583
    Abstract: Bonding to calcified tissues, including human teeth, tooth dentine and bone, is achieved through the medium of crystal growth adhered to the tissue. The crystals preferably comprise gypsum crystals which are formed by contacting the tissue surface with a mildly acidic solution containing sulphate ions. An uncured liquid resin is applied to the crystal growth and is cured to achieve adhesion by micromechanical interlock with the crystal growth and by superficial penetration of the tissue surface.
