ABSTRACT:
An orthodontic appliance such as a bracket has bonding structure that provides a greater bond strength to the tooth in regions beneath an occlusal edge portion of the base in comparison to regions beneath at least one of a mesial edge portion, distal edge portion and occlusal edge portion of the base. The weaker bond strengths beneath the mesial edge portion, the distal edge portion and/or the gingival edge portion facilitate removal of the appliance by the orthodontist when desired. The higher bond strength beneath the occlusal edge portion is sufficient to securely retain the appliance on the tooth and safely resist the forces normally encountered during orthodontic treatment.
