27
Q

What is the difference between “copy milling” and “CAD/CAM milling?”

A

Copy Milling = mechanical scanner (uses replica as guide)

CAD/CAM milling = optical scanner (uses digital information)

28
Q

CAD/CAM was introduced into industrial settings in the _____ and the first CEREC 2D design software was introduced in the ______ (when sharples graduated).

A

1950s

A

Lithium Disilicate (IPS e.MAX)

48
Q

Why is it important that you indicate the material choice prior to milling a restoration?

A

the restoration WILL shrink, the system will take this into consideration based on the material of choice
