David,
As I read through the archives and other sources your experience seemed to be the exception - particularly for those out a few years. Side note: reading the archives and your responses is what prompted me to ask where the trays were since they took impressions right before Tx.
Anyway - the advice from both is sound to take care of what I have, but it sounds difficult at the least to get implants or dentures physically if we start having problems? Unfortunately for us the comment on the cost makes sense if insurance will not pay.
