Hi, I think maybe my mum can help you with this as she had her upper right jaw removed and roof of her mouth, but here in the Uk they took skull matter from her head to seal the gap between nose and mouth and this was very successful and she now wears a plate, which is like a very thick false denture, to fill the gap where her jaw once was. Whilst it wasnt the nicest of operations, she recovered quite quickly, her scars have healed, she is coping with the large denture and whilst it isnt the nicest thing to go through, after all she did have cancer, you wouldnt know she has had the op and looks no different to anyone else with dentures. She has made a good recovery and has quality of life. I wish you well and if you would like my mother to answer any of your questions, contact me privately and I will put the questions to her, best wishes su
