Abstract
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.
