Abstract
A method of bonding ceramic brackets to teeth using silane coupling where the bond strength can be controlled by the application of a layer of organic paint. The method comprises the application of a silane coupling agent to the base surface of a bracket and the application of an organic paint to the entirety or a portion of the silane coupling agent such that when an organic adhesive is applied to the base surface of the bracket, the organic paint partially shields the silane coupling and thereby lowers the bond strength. The organic paint can be applied in different configurations to the silane coupling agent on the base surface of the bracket such that bond strength is decreased only over select areas of the base surface.
