LiSi pressing success ?

[ps2thtec]

Thinking of trying these but found posts about failures pressing . Could someone please post a screen shot
of their program on a ep3000 oven that has given good pressings? Much appreciated.
Or any other insight.

Maybe you've got to use bricks like the crazy Russian guy?

Ive already had 2 of the maybe over a dozen units that Ive done in LiSi shatter when seated.. Not to discourage you, but the grass isnt always as green as you hoped...

Weren't they shut down by Ivoclar?

It's still pending? Somewhere here there was a thread about it.

Which are the products being discussed, right? Announcement mentions LiSi Press specifcally, eh?

Ive had 2 premolars shear off at the margin. One case had two impressions and there was clearly a fit issue between the two, the entire lingual broke off at seat.

I'm not trying to bash the product, but Ive used emax for a decade now and I can honestly say, that breakage like that is very very rare. That is what raised my eyebrows. I can tell you with certainty, LiSi is a MUCH softer material than emax. Its quite obvious just in cutting the sprue. I wouldn't say it doesn't have a place, because it is beautiful, but just a heads up. Its probably more of inbetween empress and emax in terms of strength. Just my opinion, no harm meant to GC, as Ive used solely GC porcelain for a decade also.

by the way i have just been informed by the gc rep that ivoclar has dropped the law suite against them.he didnt know the reason but i feel that they didnt even come to a financial agreement or anything. time will tell
