I'm a few months late, but my husband had a partial maxillectomy to remove his palate in 2013. He has also been experiencing issues with his obturator. The fit is good (he says), very tight, but his molars on either side are loose and rotting. Either molar could fall out at any time, leaving him with no anchor to hold the obturator. If it happens, I guess temporary denture glue could help for a bit, but having any gaps drives him crazy. Gaps cause him issues with swallowing, speaking, having beverages or moist foods drip out through his nose...

He's been having a hell of a time finding anyone willing to do the flap procedure, or put in dental implants, or any procedure, to help. Radiation history is likely why, but I'm not sure. Two of his old specialists have died, others moved, one of his original surgeons refuses to do flap procedures anymore and highly recommends not to do it, and gave us gruesome examples he's seen first-hand, out of very genuine compassion. New contacts we've reach out to sound unfamiliar but 'willing to try' different surgical options (yikes & what the heck).

I wish I had something to offer you, right now. We'll have to travel to a find somebody who knows what to do. Might take months to get this sorted, but if you buzz back sometime, I'll update. If he could find a way to make an obturator work without flap surgery and without molars, he absolutely would do that.
