Hi every one,
I would like to know if some one tried to wax over zirconia rod and press with E max to do a post and core

or if some one has done a composite post and core with a fiber. I use to use the sculpture systeme i dont know if its a good idea.

zirpress over a post? im pretty sure thats exactly what a cosmo post is. you couldnt do e.max press because of the cte.

I have checked the cosmo post, thanks for the reply, i guess there are some limitations with this systeme...
I will call ivoclar to get some more info.

go for zirconium post and zirconium crown veneered with porcelain
it will last for really long time and look natural

I waxed a few post and cores and than scanned them into my system. Sent them off and had them milled out of Zr. The problem is the sprue attachments. It's hard to get them finished down good before sintering I guess. I had to do a lot of adjustment when I got the posts back. Looked good afterwards though.
