Abstract
Method and tool for fracturing the cement interface between a crown and a tooth or the like. The method is accomplished by positioning a piezoelectric driven rapid impacting tool against one side of a portion of a crown covering the tooth. The tool is covered with a malleable metal and is interfacing abutment with said crown. The opposite side of the crown is abutted against an anvil which is covered with a thicker malleable metal interface.
