Abstract
The adhesive strength of alumina brackets to acrylic adhesive cements is enhanced by forming an essentially silica coating on the bonding surface of the bracket by the steps of coating said surface with an organosilicon compound such as a silane and then pyrolyzing the organosilicon coating to volatilize the organic components thereof to thereby leave an essentially silica coating.
