[QUOTE="AL1, post: 22335, member: 854"] In my opinion, for all of them to crack like that, it would be highly unusual to be from masticatory forces. I am wondering if there were micro fractures either from pressing, cutting off the sprue or baking. Then when seated the hydraulic pressure forced the fractures. Or the wrong cement was used with an incompatible cte . That happened to me on a six unit anterior veneer case on the Dr.`s wife. They were regular porc. and he decided to use a new bonding cement he never used before. They all cracked and he had to cut them off and we started over. Needless to say his wife was not happy.
