Composite Block Defoaming Solution
A Defoaming Solution is recommended when milling resin-containing or composite blocks. Without the defoaming solution, the
milling fluid may foam and overflow.
1
After inserting the composite block into the milling chamber, shake the bottle of defoaming solution and position it over the
chamber.
2
Press down once to release the solution directly into the milling chamber.
3
Close the chamber and begin the milling process as explained below.
Milling Zirconia
See the manufacturer’s Instructions for Use provided with the zirconia blocks for processing instructions.
Scale Factor
Zirconia shrinks in the sintering oven. There are numbers on the side of the blocks. The Mill asks for the Scale Factor before a
zirconia block is milled. The system will increase the size of the restoration according to this number. This means you cannot test
the fit of the restoration before sintering.
Cleaning the Tank
The mill will prompt you to clean the tank. It is necessary to clean the mill and change the water
before
milling zirconia. If the
zirconia is contaminated with other materials,
it will turn green when sintered.
Cleaning after milling is recommended because
the zirconia acts as a thickening agent with the water. It is not necessary to clean in between sequential zirconia jobs, although the
mill will ask if the tank is clean.
Long Tools Required
Longer tools are required to mill Zirconia: Conical 12.6 and Tapered 13.2
Starting Milling
Milling is an automated process that varies in length of time based on the restoration data.
1
After inserting the block, close the lid firmly and wait for the lid lights to turn green.
The system checks the positioning of the block and begins generating the toolpath.
Once the toolpath has been generated, the milling will begin and the milling time will be displayed.
See the Troubleshooting section if you experience a problem generating a tool path or if the mill times out.
After the milling process is complete, the lid automatically opens.
2
Remove the restoration and any debris and close the lid firmly. This allows the mill to prepare for the next job.
