With the optimally formed Piccolo diamond-coated burs (1,2) all cavity preparations can be prepared fracture-free (5).

Preparation is achieved with the 90 µm diamond-grain bur (3), finishing with the 25 µm diamond-grain bur (4). In order not to damage the adjacent teeth the use of the Cavishape®-file or Bevelshape®-file is also recommended.
