[QUOTE="paulg100, post: 44515, member: 1643"] "Zirkonzahn scanner precision about 9 microns and milling unit 1 micron" ill eat my shorts if that mill has an accuracy of 1um. Even the xx ton industrial units would have a hard time hitting that, if at all. "then scanner's maximum mistake/accuracy is about 250 microns " That sounds reasonable to me from the silly results im getting. But the easiest test i find, is that if you can see the gap with the unaided eye then its 100um + and that aint any use for dentistry. If anyone ever questions that then a quick google search should find the published data. eye no see < 100um. Its getting quite laughable, i just called the Sirona tech helpline again today, and the guy i spoke to didnt knowANYONE at Sirona who would know how acurate there scanners are, ive never heard a german guy squirm on the phone before. Man im like a pitbull now, not letting go of this if it takes a thousand calls and letters and more..... [/QUOTE]
