Abstract
Debonding of cemented orthodontic brackets from teeth by application of a quick twisting force to fracture the adhesive bond. A torquing tool has slotted ends making a close slip fit over mesial and distal side surfaces of the bracket, and has a flattened center section providing a good tactile sense of applied force. The method and tool are especially useful with brackets made of brittle ceramic material.
