Titanium blanks are the hottest topic in digital dentistry in 2019. A lot of new milling machines can mill emax, zirconia, and custom metal abutments.
One of the parameters to keep in mind when milling them is the diameter of the screw access channel. Most CAM will carve them out but leave a lot of finishing processes remaining.
We’ve tested quite a lot of mills with the imes icore coritec one and the milbox cam software. If you set the settings to 2.5 mm’s , you can pee off the excess sprue material with just finger pressure, dramatically reducing the free hand work that you would have to do.
The pin diameter at object and at material under 2.5 mm’s will give you inconsistent results.
