[QUOTE="DMC, post: 61150, member: 430"] Bob, So I guess you have tried Amann Girrbach's new HT stuff? Bloodent? Upcera? TD Dental? Sagemax? Lava Plus? etc, etc..... Ivoclar's new stuff? Many of those have quite a percentage of Hafnium-Oxide and AlO2 and look very nice! And you have seen them all and you have the most translucent huh? Also, in your CAD design, do you even have any radius that is .3mm? Have you bothered to measure the maximum radius of mesh to match up with your milling tool? Ask one of your Computer Gurus to measure it one day. I think you are wasting your time with .3mm on the exterior of crown. I could possible see using it on internal surface, if customer has NOT applied any radius-compensation in the CAD software (which most all people do use it.) Do you have your customers change their setting in 3Shape to match your tool radius? If not, then that too is a waste of time. I find that most people are using at least .7m radius compensation, or more. So....we only use small tools on inside fo special cases that have been designed to be milled with such tools. Like a very flared out anterior prep. We would not choose to use any extra spacing for compensation of tools, but rather step down to extreme small tools for CAM and mlling that one case. [/QUOTE]
