Hi,
I have a full arch case due Monday morning. I have cemented the PMMA bridge to the titanium inserts (they are conical) 2 times, Both times it came loose as I was screwing it to the model with the tissue in place(after curing overnight). The first time was with 3m Rely-X (which is what one of the large milling centers uses and the 2nd time I used Ivoclar Multilink Hybrid Abutment.
I sandblasted the mating surfaces and used Monobond on the Multilink
Can anyone tell me why it is coming loose and how to keep it from de-bonding?
Any help would be greatly appreciated as it is Saturday evening and patient is coming in Monday 8am
Thanks
