Hi guys, got a new metal milling machine for my all on X cases and of course as every new thing first attempts were not a success. I receive inaccuracies (not a passive fit) on my first long span implant restorations and convinced I mess up something with the marker scanning as cement retained cases are coming perfect. I use OpenTechnologies Deluxe scanner and Medit SE, 5 axis Yenadent mill with 2,7kW IMT spindle ,250W servos and Mayka CAM. I have no experience milling implant connections till now I used VHF to mill zirkonia and emax mainly, so any suggestions would be helpful. Basically I did 3 times one all on 4 case, first time scanned with the Deluxe scanner, scan markers on 2 stages and scanning software merged everything. Second time again with Deluxe but scanned all markers together and merged data in Exocad. Third time used the old Medit SE , again all markers together and merged data in Exocad. Unfortunately nothing fitted perfectly, there was always one bar pillar not fitting (not on the same implant). Believe it or not best result was with the old Medit scanner, inaccuracy was lets say 50-100 micron in the middle implant , rest fitted perfect. I assume scanning of the markers is the issue, as did few smaller implant bridges and were fitting perfect . As I mentioned have zero experience with long span implant restoration scanning and manufacturing , but the scan markers scans does not seem smooth enough . I tried using nano scan gel , but mesh doesn't seem good as when you scan plaster for example. Would appreciate any advice, thank you.
