Zirconia Marginal Chipping when milling

Christopher Nelson, CDT · October 1, 2013

We don't use Sirona but rather Amann Girrbaach. I occasionally get a chipped margin but it is usually due to dull burs or someone touching the machine during a program. If you are using fresh burs and the machine is calibrated properly, I question the quality of the bur and the spindle.
