Bone Mill KM 3 - Producing autologous bone chips - With the help of the KM-3, the largest possible volume of bone chips can be produced from the bone blocks -

Producing autologous bone chips with the bonemill KM-3
In order to correct big bone-defects, bone has to be taken out at other intra-oral positions frequently. The bigger bone-pieces, as well as bone-blocks, are out-separated with a trepan-drill for example. The bone-mill finds its use in grinding of these bone-blocks. The purpose is to generate an utmost volume at bone-chips from the bone-blocks. The chips should be granulated consistency to be well adaptable in the bone-bed. Autologus bone transplant has better properties than any other bone replacement material.

The bonemill KM-3
The special-cut-cylinder of the bonemill KM-3 has been developed in order to get granulated bonechips.
The cut-cylinder owns vacuum solidified straight, teethed with a special-wave-cut. Short granulated bone-pieces originate that show a length of 1,6 mm at most. These kind of bone-chips can be applied better so that the bone-groth of the new bone is secured. Studies confirm, that autologous bone transplant is clearly superior to all allogenic, xenogenic and alloplastic materials for the reconstruction of bones. On the basis of the wave-cut, working the mill is easy.

The application
The bone-pieces are being put into the openig of the bonemill KM-3 and pressed with the pressurepiece onto the special-cutting-cylinder. The cutting-process is enforced by the twirl of the grip and simultaneous pushing down of the pressure-piece. In the bonemill, the edges of the special-cutcylinder provide the comminution of the bone-pieces. Through variation of the pressure during the pushing-down and the rotational speeds of the grip, the size of the particles that fall into the plate of the mill downward, changes. Consequently, the bone-pieces are prepared virtually loss-free. A cutting comminution of the bone is more sparing and preserves the structure of the bone-material.
