The workflow for restoration is as follows:

1. CAUTION!Wear gloves.

2. Open the working chamber door.

3. Loosen the 2 fixing screws on the blank holder without unscrewing them.

4. Remove the blank from the blank holder if present.



 



 

5. Use the disc as follows:

1. If the disc is multilayered, align the blank so that the top layer of color points to you.

2. If the disc was already machined, ensure that:
   • The original front faces towards the front.
   • If the disc has been marked for safer remounting via DentalCNC, ensure that the marking is in the position shown below.

3. Insert the disc from above into the holder.



 

6. Carefully rotate blanks that have already been machined so that the marking on the blank is exactly above the marking on the blank holder.

   

    

NOTICE! Blank damage due to machining residue and incorrect fixing in place

7. Remove machining residue from the back of the clamping elements with a brush. Do not use compressed air!

8. Tighten the fixing screws (marked orange) with the supplied torque screwdriver (1.5 Nm) as follows:

   1. Screw in the left screw without triggering the torque limitation.

   2. Screw in the right screw without triggering the torque limitation.

   3. Tighten the left screw.

   4. Tighten the right screw.

Torque
1.5 Nm For a less stable material such as zirconia, you can use a lower torque.
