Crystal Ultra?

The thing is if this is any indication of where materials will be going it will just drive the pricing down per puck like zirconia

It will also drive the price of implants down too.
In fact it has potential to eliminate the need for an implant altogether.

I'm doing a full upper and lower bridge on implants from a very similar material on my wife right now. Can't give out the material and who makes it yet.I will take pictures and post if I can get the OK. I don't think it will be big in the single unit part of C&B. This is however about to change the all on four and implant dentures for sure and dentures not far down the road.

If anyone is going to Chicago. You can check them out there as they will be exhibiting.

Scott Atkin is the Principal at Dental Laboratory Milling Supplies L L C

Does the name ring the bell for anybody?

this is a rebrand - but my NDA prohibits me from saying who this is from. There is a lab we are very friendly with that has been beta testing for i think 4-6 months already and seem to be getting better results than Lava Ultimate and you can mill bridges. - however it's wet mill.

Sounds a little to good to be true... I want to try it!

Sam!
You're not dodging my email are you!?

Sam!
You're not dodging my email are you!?

No, yes. Haha. Just sent you an email.

Interesting !

Haha, okay thanks. Didn't realize you were on DLN. Good to see you here

Good Luck trying to Grind creamic anything from the top-down in 98mm disk form!

What tools are you guys thinking will work for that exactly?

You really need to come from the sides grinding w/diamonds, in single cube form of the material.

Probably just relabeled Vita or Dentsply stuff.

Crystal people don't make anything.

 

[ParkwayDental]

Scott, I am going to mill it with carbide tools and test it out wet and dry to see how it does?

You are right you cannot grind this material but I don't think it has to be. I think carbide tools will be just fine.

710 MPa huh? Getting close to Titanium!
You need larger tools to rough with (4mm Torus) and a larger mill to get serious with this material IMO.
Also flood-coolant and not a mist. No Datron.
This calls for a HAAS and very specialized strategy and unique set of tools!
No simple 2 flute balls.
Tyler, you will have issues right from the beginning milling this stuff I bet...?
Almost 2x harder than trying to mill eMax you know?

I don't know about that Scott, I could be wrong but if Crystal is selling this then the probably can use it in their tiny Dentmills they have since they are kind of partnered together.

 

[DMC]

Someone explain this to me.....

One place says this material is 710 MPa Vickers Hardness.....(Isn't Natural Enamel around 340?)

Then this weird photo below....Those other materials are NOT that high in Vickers!!?? Total B.S. chart! LOL

Then to say this crystal stuff is almost the same as natural teeth, while in reality being 2x as hard is also B.S.

?? Did I miss something?

How many shades does it come in?

The Shades are really limited right now I think they only have 3 or 4 pucks.

Then again, these are the same jack-holes that tried to sell us all overpriced, crappy microwave sintering furnaces from China that did a horrible job! LOL

I wouldn't put anything past them. I have a funny story about One of those guys I wish I could tell ya in public!

Your theory is very flawed Tyler. How would they know how to design a mill for a material that didn't even exist yet? DentMill is a very old design, even the newer Ones...

Just ordered my puck shade A2 15mm. They said it can be milled both wet and dry!
