<p>This invention is a method and tool for fracturing the interface between dental structures that have been cemented together. The method is accomplished by positioning a rapid impacting tool (21) at about 90 degrees against the one side of the lower portion of a cap (15) covering a tooth (13). The opposite side of the cap is abutted with a kinetic energy absorbing element (27). The flexing against the cap (15) is small while the frequency is high.</p> |
