A method of direct or indirect bonding orthodontic brackets including metal, ceramic, sapphire, plastic and other clear brackets to teeth utilizing light curable polymer bonding agent compounds which are sufficiently viscous in an uncured state to retain a bracket in an applied position on the tooth

A method of direct or indirect bonding orthodontic brackets including metal, ceramic, sapphire, plastic and other clear brackets to teeth utilizing light curable polymer bonding agent compounds which are sufficiently viscous in an uncured state to retain a bracket in an applied position on the tooth until the bonding agent is cured and which bonding agents are curable within approximately twenty (20) seconds or less, by directing a visible and/or ultraviolet light source between the base of the bracket and the tooth to thereby thoroughly and securely bond the bracket to the tooth in the desired position. The method subsequently permits the bracket to be removed simultaneously with most of the bonding agent attached thereto thereby facilitating tooth cleaning following bracket removal.

A method for bonding orthodontic brackets to teeth comprising the steps of: cleaning the surface of the tooth in the area to which the bracket is to be applied; etching the surface of teh tooth and drying the ethced area where the bracket is to be placed; applying a photopolymerizable liquid bonding mixture to the etched area of the tooth; applying a photopolymerizable bonding agent composite to the base of the bracket wherein the composite is sufficiently viscous in an uncured state to retain the bracket in position on the tooth when the bracket is applied thereto; applying the base of the bracket to the etched area of the tooth by applying sufficient pressure to the bracket to expel composition therefrom; insuring proper positioning of the bracket; applying sufficient pressure to the bracket to insure the base is securely seated against the tooth and to expel any remaining excess composition or air from the tooth bracket interface to insure intimate contact at the tooth bracket interface; directing a primarily visible light source from the bracket side of the tooth to the interface between the tooth and the base of the bracket to cure the bonding agent and securely fix the bracket to the tooth in a period of less than twenty seconds.
