emax Patent Expired

[Mark Jackson]

The patent for Lithium Disilicate, actually originally given to Jeneric Pentron and purchased by Ivoclar has now expired. Glidewell has been sitting on their infused LDS, called Obsidion....let the games begin.

 

[Tom Moore]

Hot Dog, let the capitalism begin. From competition shakes out the best for the dollar spent.

What about GC, I heard they have one to ?

 

[Gdentallab]

So that's why some dental companies are promoting ingots claiming they are better than emax . But the launching in the near future.

 

[paulg100]

Good good good, looking forward to seeing where things go.

 

[Gdentallab]

What about GC, I heard they have one to ?

that's what i heard. Price less than the emax with 6 ingots instead of 5. I mean the price of 6 ingots is less than 5 emax.

 

[Toast]

I don't mind the competition but my drs. ask for e.max by name so unless there's a huge difference in strength I'm not about to change it. I can get two sometimes three units out of one ingot so material cost is $11 or less per unit. Six ingots for the price of five isn't a good enough reason alone to get too excited....yet. I doubt Ivoclar will be lowering their price.

 

[Mark Jackson]

I doubt Ivoclar will be lowering their price.

Me too. I agree with you 100%. emax is the product with all the name recognition. The problem as I see it, is there will be a ton of cheap LDS now, and emax will get counterfeited, just like BruxZir and will take a dive in pricing to dentists.

By the same token, some of the new materials may really be good. Some minor changes in chemistry might wring out some extra strength

By the Same token, emax has now been around for about seven years who's to say one of these new products doesn't have problems down the line?

Me too. I agree with you 100%. emax is the product with all the name recognition.

Maybe true, but have not had a doc ask specifically for Lava in a long time. So i think time will tell before name recognition dies down.

The problem as I see it, is there will be a ton of cheap LDS now, and emax will get counterfeited, just like BruxZir and will take a dive in pricing to dentists.

Maybe, but its not all going to be cheap....gotta have hope in other companies man there not all bad. True about the price dive but who wants to do work for those cheap ass dentist's anyways. But i guess you have a huge overhead to cover you need all the cheap ass's you can.

By the same token, some of the new materials may really be good. Some minor changes in chemistry might wring out some extra strength

Excited to see more than one company advancing a great product.

So what do you think 10 years from now there wont be a bridge placed anymore or is that too little of time? GP's will be placing 75% implants and there wont be a need to ruin 2 perfectly fine abutments for 1.

 

[charles007]

The only prices we will Ever see dropping, are lab prices....
Emax, the #1 most reconized crown anywhere, zero chance of Ivoclar lowering the price

does any one know when glidewell will start selling there version

I am all for competition in the materials arena. It will produce better products for us to use. Mark, my Patterson service tech mentioned something about the development of sapphire stabilized zirconia to me awhile back. I think it was sapphire, hear anything about that? Zirconia with the translucency of emax.

I have some pictures of some of the new fortified materials that I will share soon. I think we have some exciting new materials coming our way before too long. I'm much more a materials geek than a technology geek.

I'm pretty sure it's Pixie Dust sprinkeled in the mix by Keebler Elves.
Top secret location behind Al's house in KY. That's the rumor I heard.

I saw a copy of a patent last night that was issued in Germany for a new LDS product, "and method of manufacturing such material".

I just heard this.also. I was told Ivoclar has multiple patents on various LD formulas and as mentioned above the Eris patent has expired not e.max.
