First Modeless Case......kinda

    I thought I'd share my first modeless case with everyone since it's Friday and I dont got shit to do. I'll take you through the steps involved so that when you're ready, you have sort of a guide.

    First off, I'm using 3M truf def digital scans. Pain in the ASS at first and to get everything the way you want it, but once its all configured its a breeze.

    First Step, become a 3M margin marking lab. This makes things 10 times easier. Call 800-634-2249, option 3, then option 1. They send you 4 different videos, watch them.
    Full Video: http://multimedia.3m.com/mws/media/1049238O/margin-marking-full-mp4.mp4

    Onlay: http://multimedia.3m.com/mws/media/1049239O/margin-marking-onlay-mp4.mp4
    Bridge: http://multimedia.3m.com/mws/media/1049237O/margin-marking-bridge-mp4.mp4


    Then they send you 10 practice cases. Keep in mind that your 3D mouse will not work (at least I couldnt figure it out) while using there software. After completing the 10 cases they send you your 4 "test" cases. Complete those and in about an hour, you are officially a margin marking lab.

    Now I say become a margin marking lab because if you don't you basically have to pay some company to mark the margins for you and pay $8 for each margin marked. You could also just download the .stl files from 3M but sometimes there will be missing data because you arent using their software to mark the margins. In their software you can use the actual images of the prep to mark the margins and this can be quite helpful sometimes.

    THE MOST CRUCIAL PART

    Regardless of whether you become a margin marking lab or not. You must call Call 800-634-2249, option 3, then option 1. Tell them you want 3M to give you the .exo files with each case. This allows you to simply download the file from the 3M website, start a new case, click load button, import 3M tru def, find the file and design. If you don't have the 3M tru def import button, call your re-seller and have them install it. (Im sure the code for it in on this site somewhere though)

    Now I said I'm kinda going modeless because after I have design the case, I'm still going to have a die milled/printed. I have to be able to finish down the margin and have something to use to hold the crown in place for stain/glaze

    Im actually milling out the crown and die as I type so I'll keep you updated with how it goes and some more pictures. If you have any questions feel free to ask

    Thanks for posting this info. Now when I get s PM about True Def I can send them a link to this thread instead of saying IDK.

    Ive learned so much from all you guys on this forum and the "other" one that I feel I need to give back when I can.

    in 30 minutes I have a die and a crown. Now I just need to sinter it.

    With emax blocks you can have a finished crown in less than an hour. Get your settings dialed in and around offer a premium fast crown for 3x + your normal fee. Not all people don't want to go to the dentist more than once for a crown.

    Toothman 19, Nice post....* anatomy grooves looks nice and deep, what library. What setup do you have....mill and bur sizes....and mill time strat?

    I use the heroes library. I also use a .3mm bur for the anatomy, 2.5 for roughing and 1.0 for finishing. Gives a "high definition" look. Using the .3 I feel makes a huge difference. I'm milling on the wieland zenotec select. It's been a real nice addition to the lab. The library helps too. That design is the Aida anatomy.

    We are also using the Noritake Katana zirconia, I'll post a picture of it out of the sintering oven. They look fantastic with the multiple layers. We do a little outsource work if anyone wants to give it a try.

    As far as same day emax, that's the ultimate plan. We'll see if I can find some more digital doctors. I've really only been working with one so far. Does anyone know a good way I can find some local doctors, websites that might have a list of them? Probably need to get in touch with the local rep of each scanner

    Can you post a screen-shot for the milling path of the 0.3mm please?

    I am very curious what approach was used for calculating the milling path on the occlusal side.

    Yea. I'll post one on Monday. Keep in mind, these are wieland's strategies and not my own. I haven't begun to tackle the beast of making milling strategies yet

    Hmmm, Not exactly a "Smart toolpath".

    Looks like a waste of time to me.

    Should look more like this and take around 10-20 seconds.

    Thanks Brad!

    One pass is enough for the secondary anatomy.

    Your cam goes round and round too many times and mills areas that have already been finished IMO

    I could narrow the occlusal area that it goes over. I just always hit the automatic button and it paints the anatomy where the .3 bur is supposed to go. I'll stop being lazy.

    No, it is not that.

    It is the number of extra passes that your CAM is set to do, after auto-recognition of the tight radius areas for the secondary anatomy.

    One pass is enough IMO.

    Here is the finished product. We just finished down the margins on the die, added a little stain here and there, and glazed.

    This is an A3 Noritake Katana STML. I'll see if I can get some pictures of it in the mouth
