This case is certainly not the prettiest, but I wanted to play with NT Trading’s Scan Post, Reusable Lab Analog and it ti base on another Alien Milling el cheapo case. Spoiler Alert: Meh. Could I have done this chair side? Absolutely. But just wanted to see the difference is esthetics between CEREC Zirocnia and Katana. With a two day turnaround thats not much different than doing it myself.
On the surface one may think that the price of Alien vs CEREC is much cheaper, yes the parts are cheaper, but when they all add up a screw retained Emax is $145 and a screw retained Zirconia from Alien is $101. I will say that I prefer the NT trading scan posts as they are all PEEK and you can’t screw them up like the two piece scan posts we have in CEREC.

Designed the the two restorations in ExoCAD and literally got them back two days later. I had another case that I did with Emax LT and you can see that Emax is slightly more translucent than the standard Alien Zirconia, but not that much more.
The one thing that I do not like about lab milled Zirconia implant restorations with ti bases is that the fit on the ti base is a little loose. CEREC has pre milled holes for the ti bases and its hard to screw those up (no pun intended). Labs recommend a “screwmentable” type of cementation process where you treat the ti base in the mouth, the crown is cemented in the mouth on the ti base, then unscrewed and cleaned. End result was OK, but I think if I did Emax it would have turned out better. But not bad for a total lab bill of $123 for both including ti base.
