[QUOTE="Drizzt, post: 93485, member: 4075"] I wouldn't go for a laser scanner if I were you . I can understand that you are mostly interested for big implant cases , so you will need the best accuracy you can get , both from your scanner and your mill . Structured light scanners(Medit,Imetric,SmartOptics,etc) are more accurate than laser scanners (3Shape , Dental Wings) . And as Scott said , you get what you're paying for . I have heard many Medit users that are perfectly happy with it , even for large cases . If I was buying now , I would buy this scanner . As for the milling machine , I don't think that 450i is what you're looking for . I have a customized Yenadent D 40 , and I am milling all my metal with it , either it is simple crown & bridge , or implant substructures . I also mill my own custom abutments out of titanium, including the interface . You can check some of my work here ( [url=http://s1085.photobucket.com/albums/j433/drizzt85/]drizzt85's Library | Photobucket[/url] . It weighs 650 kg and has many modifications compared to the standard model . So far I am perfectly happy with , with the times and the accuracy . But still if I had more money to spend , I would buy the bigger DC 40 , or something even bigger ! Although I haven't seen a milled full arch implant case out of 450 i , I simply can't believe that a machine so small , that was not made for metal milling initially , can mill a so complex case with the needed accuracy . Plus , when I saw it in action at an exhibition , it was soooo slow ! 45 minutes for a coping . I mill 20 minutes average , depending on the disc thickness . So if you want to mill these cases inhouse , you'd better start looking for the expensive toys . You can always buy a nice scanner and outsource those cases to a milling center . Do you have the volume to support a large investment ? I mean , how many of those cases you having per month ? Will it be a wise decision for you to invest 250.000 $ or more for a setup that will really do what you want it to do ? [/QUOTE]
