To increase the minimal invasivity and a-traumaticity of the procedures, modeling the bone in a safe and controlled manner. The Magnetic Mallet re-shape the bone, without removing it. This opens an ample range of new options to treat the cases otherwise not doable using drills or other cutting instruments. It also speeds up the procedure compared to manual tools or other traditional tools. It does not generate any heat on the bone, therefore it does not need any irrigation water.
