[QUOTE="Accutech, post: 330712, member: 981"] I see a significant amount of difference in marginal adaptation and integrity. I get good margins and overall fit with 0.6 mm burs but with 0.3 mm burs milling in HD on my Ceramill 5X, the margins are superb (under 1.5 X magnification) and the intaglio fit near 1 mm marginal finish line is snug, but not too tight. As far as surface anatomy and texture, the sprue / support pin placement ruins all that and surrounding surface areas anyways so I don’t spend too much time worrying about it. I just go over everything by hand so no, I don’t benefit in terms of facial/ surface anatomy, [ATTACH type="full"]37509[/ATTACH] [/QUOTE]
