    Just wondering what others are using for cementation of emax crowns/onlays/crown lays? What's your protocol?

    Michael has some good tips, I'll use the floss under the contact one a fair bit.  Personally I don't tack cure, maybe I'm just a chicken, but I let the cement chemically get to gel phase and get cleaning.  I'll get the buccal and lingual cleaned up first with a rubber tip then start proximal…

    Ivoclar Vivadent created a handy website that walks you through the steps for cementation (bonding) to natural teeth, implants and posts.  Click on the image to go to the website:     [attachment=206:cns.jpg]     If you would like to use the system on your Apple device, then download this app!

    I use gluma desensitizer before bonding, scrub for 30 seconds , quick rinse and dry , then bond , i agree with mike you need to scrub multlink bond well and you will have less sensitivity

    Ok so this is the background on this case, over a year ago I made these yamashita adhesion bridges for a patient waiting for bone graft and  implants to integrate. I did not do a staple prep like a traditional one wing adhesion bridge, I did absolutely nothing. Furthermore,  I did not etch the enamel…

    hi again,   It was a challenge to hide the darkness from the gingiva on the pontic as you can see. I tried to paint it with a thick layer of white and yellow an the basis of the pontic. Do you have any good advises here?   Peter Denmark

    Apparently 3M has changed the indications for Lava Ultimate:   Indications       Lavaâ„¢ Ultimate Restorative is indicated for:   Onlays   Inlays   Veneers     No longer indicated for full crowns.  Debonding is the issue, probably due to the materials flex.  Personally I've only ever used it for Onlays and those all…

    Wally,   Would you agree that even in cases where there may be not added bond strength benefit from phosphoric acid etch, there will also be no decrease AND the phosphoric acid will clean the bonding surface of oils or other contaminates that could degrade the bond?   Yes especially if you are using hemostatic…

    What's everyone using for brand and sizes? and what hemostatic agents with it?

    Ultradent, 00 for first cord, normally a 2 for the second or sometimes a 1 depending on the tissue.

    Just go my new Form 2 3D printer. This thing is the real deal. Can print all my Planscan models for very large cases and implant surgical guides and stuff!  So cool. The thing was only about 4k still playing with it. But the fits from the crowns milled from an intraoral scan then seated…

    Hi everybody! This is an excellent forum! Tons of valuable information! Congrats to all that contribute!! I have been looking into 3D printers in the past month as well. Blue Sky Bio is making huge advertisement with the CEL Robox printer, which costs less than half of the Form2!! Does anybody have any experience with this…

    Hi all, I'm having difficulty choosing shades for my first order of Emax/Empress. I can't order everything, so just want to figure out what the most common shades would be a good starting point. Thanks!

    Hi folks, I wanted to share very simple and free tool from Ivoclar for block's shade selection. You could find it both in Google Play and AppStore. I find it pretty useful. Try to play, may be you like it.

    Many of my older patients are falling apart dentally faster than I can put them back together, mainly with recurrent root decay under crowns. They simply cannot afford new ceramic crowns.  One of the topics in last month's Clinicians Report was fabricating low-cost resin crowns for geriatric patients. The technique Christensen presented was to basically fabricate a…

    Here's a follow up question:  If you were to be planning occlusal veneers to increase vertical dimension for a patient, would you consider using CeraSmart or the old Lava MZ100 blocks?

    Dr. and I have been throwing around the idea of designing a Maryland type bridge. Based on the picture attached, can anyone tell me if A) This is possible to mill, and B) what material would be best. Thanks for the input!

    Hi everyone, I would really like to try a Zirconia block now. I have been told by the Henry Schein representative in Europe that they don't have any blocks that fit in the Planmill, only CEREC. Is that true? What do you guys know? I have used the search on the forum and I found…

    Mike Kelliher made the last post
    Completely agree, other than the ability to lute it rather than bond I don't see the big deal with Zr.  It's not as nice looking and you can't bond it.  I will use it when I have space limitations as it can be thinner but for those few it's easy to send those out, don't…

    I don't know if anyone else has noticed, but the e.max crowns tend to finish lighter than the shade tab itself. Dr. and I were thinking about using the left over block stumps for shade guides...does anyone know if you are able to put the whole thing in the oven, metal and all?   Thanks
    Shanalee made the last post
    Thanks. I think this is probably where Dr. came up with the idea! Yes, that seems like a pricey way to do it! We did try once just doing a bit of glaze and stain in the occlusal grooves, crystallizing it, then just polishing the finished crown and I feel like that better reflected the…

    Just got an email from my Schein rep asking if I wanted to try the Cerasmart blocks.  Has anybody tried these yet?  If so, what are your impressions.   Looks like an alternative to Lava.  Can't imagine they are as strong or pretty as E-Max?   Thanks
    Mike Kelliher
    Mike Kelliher made the last post
    Haven't tried either Cerasmart or Vita Enamic, both are resin based materials.  Personally I'm going to be very conservative on these.  I don't see either as a replacement for emax from a strength or esthetic standpoint.  As with Lava I may do a couple of onlay type restorations for pt's who decline an indirect simply…

    How do you achieve a C1 or C2 shade empress restoration? There is no C1 C2 empress blocks available.
    Mike Kelliher
    Mike Kelliher made the last post
    Never had to do it, but I'd get a block that's lighter, maybe a B1 and use stain to darken to what you need.

    A couple of new materials are now out for the Planfit system.  The Vita Enamic, Mark II, and Triluxe forte blocks are now in the Schein catalog.  I've attached a PDF with some info on the three materials, but basically Enamic is a resin/ceramic material that does not require firing same material class as Lava…

    Just a caveat about Enamic, we have had a couple of fractures when using these on student preps for full coverage.  Not many and it is a small sample size but we've gone to using these only for inlay, onlay type applications.  98% of what we do is still e.max.  It just works.  Also my…

    So there is a current promotion on the EmaxMT blocks. Buy 5 boxes get 1 free! It only comes in a size 14 block and 7 shades. A-1,A-2,A-3,B-1,BL-2,BL-3,BL-4[attachment=938:image.png] This is what the box looks like.[attachment=939:image.jpeg] The virtual lab slip doesn't give you the option of MT. So just go ahead and select either HT or…

    A comparable study done in the United States reported similarly shocking figures. 45 percent of American respondents said they didn’t visit the dentist regularly because they didn’t feel like it was necessary, Mark Walker dentist. “As a dental professional, that is a fairly alarming statistic and shows how important it is to educate people as…

    So for anyone in the know, will we be getting the chance to try some of the other milling block options?  Some other products out there could be promising( CeraSmart Resin, or Vita Enamic) if we would have the opportunity to at least try them. I must say that as happy as I have been…

    It's not so much a big brother thing, probably more as issue that the companies have some deal with Sirona to provide those materials exclusively for their system.  In any event none of this current batch of materials really is something you'd want to mess with anyway.  Now how would you feel if you had…
