[QUOTE="Al., post: 7750, member: 382"] Ive never heard of anything like that happening. I dont know how wax could get pushed down if there is investment against it. Could it be die lube or debublizer? Could the whole casting be underexpanded and it shows up in the tip? Mabey you could try another cc of liquid? Mabey some undercut wax or spacer on the tip? The attachment I was refering to is Nobel Biocare's snappy abutment. In their cat. I think they have a plastic coping I could use, but what I have done a dozen times is remvbe the plastic pickup female from the impression and trim it up and remove the little retention prongs in the plastic and cast that. When I trim it up a hole opens on the occlusal and I fill it in with wax. I havnt had a fit issue with this. [/QUOTE]
