    Post cure unit confusion. Newbie!

    Henry Schein etc are pushing 3D printed crowns as the replacement for a CEREC or lab and dentists are buying it hook line and sinker. I did the first documented case of Bego veneers on a lady 48 hours before her daughter’s wedding and they lasted for 9 months before debonding. I “developed”...

    Post cure unit confusion. Newbie!

    Been studying this for 2 years at a university. So far we’ve found nitrogen and glycerine are not required. Glycerine has been shown to weaken the prints and the nitrogen has little effect but it is measurable on the outer layers only, which are usually polished away. The “best” most complete...

    For Sale Triad vlc bonding agent WTB

    Tokyumo Universal Bond will etch and prime anything for Triad or anything else to stick to. Put it on a Locator housing and wait 20-30 seconds and it’ll frost over and the surface is then primed for any dental material to bond to, even Triad. They have a new single bottle primer but IDK if it’s...

    GC Optiglaze on denture

    I have found acetone or butanone based sealers are doing the best as a sealer. Taub’s Stellar Glaze is looking great so far. Then I coat with Optiglaze for the nano technology. The acetone or acetone derivative like butanone should dissolve the outer layer of the prints and create a new bonding...

    GC Optiglaze on denture

    What I was referring to was the glaze turning brownish when cured too fast with too much power. I’m doing a webinar on 3D printed veneers & temps and remember some other sealers that would turn brownish when hit with too much light intensity too fast, and the video explained everything...

    GC Optiglaze on denture

    I saw a video once on “burn in” or something like that when curing resin sealers and can’t find it anywhere. Does anyone know where to find it or more information on how to properly cure sealers like Optiglaze?

    IPA recovery system interests?

    I agree about the commercial washers. Use way too much IPA. I was using the Formwash bc I was beta testing for them. But still using beakers, Tupperwares etc the IPA saturates fast and you can just dump it into this thing and get all your IPA back. I think you’d get your money back faster than...

    IPA recovery system interests?

    What size tank would you recommend? 1 gallon, 2.5G, 5G? I’m going to try these shorter, fatter filters this week to see how fast and well they filter, and if they work, I’ll send you one to test it out for me and give feedback.

    IPA recovery system interests?

    I think I see your point about the loss of IPA, but the manufacturers recommend 95%+ IPA or ethanol for most resins, don’t they? I just did a webinar on Bego Permanent Crown resin and they recommend 95%+. BTW, that’s what’s in the photos above. Look at the bottom of the Formwash. That resin...

    IPA recovery system interests?

    Yes it works but the coffee filters only catch so much stuff. At best I was getting 70-75% IPA with 5 filters measured with a hydrometer and I lost about 15% of my initial IPA, I guess to it being absorbed by the filter paper. This uses UV light and returns 97%+ IPA after 4-6 months of heavy...

    IPA recovery system interests?

    99% IPA ranges from $15-30/gallon. I was using up 3-4 gallons/month, sometimes more. It adds up. I have a Form3b, old Moonray and EnvisionTec D4K. Like everything, they have pros and cons. Beats the heck out of stone in many ways: fit is better IMO, no bubbles, doesn’t break, etc. You have to...

    IPA recovery system interests?

    I have some new short wide filters I’m hoping will help speed things up. So you think multiple, maybe 1 gallon tanks?

    IPA recovery system interests?

    I have been working on recovery of IPA after seeing how much I was spending on it monthly. I have come up with a simple filtration system that can be made for $50-150, depending on how much IPA you’re filtering. Bigger tank = more filters = more costs. Been using the same IPA for months now and...

    Vita enamic burs life

    I even reduced the mill and spindle speed to 50% and it still broke the crown off.

    Vita enamic burs life

    I’m very interested. I have 2 copies of Millbox, one from DG Shape and one from Zahn. DG Shape has strategies for Enamic, Cerasmart and Lava Ultimate but it will not let me send the file to be milled. Zahn version gives me Cerasmart when I select resin composite but tries to use only Razorsharp...

    Roland dwx42 w

    Again based off a friend’s crown’s he’s done for me, they fit perfect and no need for 5 axis for C&B. Less chipping at the margins because of its slow speed IMO. I think that’s the reason the mills have so few problems. They don’t try to mill it in 2 minutes. I’m no expert and only have...

    Roland dwx42 w

    I have the Roland 52D and it is a tank! A bit slower than other mills but I believe that’s why it is so dependable. I have a friend with the 42 wet mill and he has never had a problem with it in 2 years. And his crowns are beautiful. I’m going to get one January 2021. I wanna see how the...

    Built my lab. Got acquired. Building another, but then what?

    10. Possibly aging DDSs don’t know how to use triple trays, VPS, etc. 11. Federal Health clinics: DDSs are nearly liability free and have no OH. I know many newer grads are skipping GPR & AEGD residencies and working in them for a “paid residency” Idk. I’m just trying to wrap my brain around...
