Ok so here is the situation, I've been a Ceramco 3 user for many years and recently switched to Ivoclar's In-Line porcelain. With my ceramco 3, I rarely had any issues with it. It was very easy to handle, decent color, etc.....BUT I have recently switched over to In-Line porcelain and here we go with the problems. The problem I am having is with the opaque bonding to my semi-precious alloy and precious alloy. At first I was getting bubbles like crazy....I talked with technical and a few labs I knew were using it and they gave me a few suggestions, and the bubbling was gone, but now I am having problems with the porcelain shearing off at the time of seating the crown. The docs are sending me pics of the crowns with at least half of the porcelain and opaque completely removed off of the crown...They are saying that during the seating of the crown, when the patient bites down the porcelain just shears right off the crown. The opaque and porcelain is coming right off the crown. The alloy is a hi palladium based alloy, even my hi-noble is a hi pd content due to the cost of it. I am using ivoclar's metals as well and it is definitely in the correct CTE range. I am using for SP-d-sign 59, and for Precious- Evolution lite.
So I am 99% sure that Im gonna change porcelains unless one of you kind people can help me out with this issue. Any help would be greatly appreciated, and many thanks to you if you reply.
Peace!
