Thanks William, I have not had any response to questions about the jawbone or been referred at all to a bone specialist!
The dental team have had me get two CT's of the Lower Jaw to check the roots of the teeth.
All that is left are the stumps of my incisors and they have acceded to my request to leave them after a special coating is applied and place the new denture in over them.
It will help in locking the Denture and reduce movement. It would seem the jawbone still has some blood supply as it comes up looking not too bad in the Scans. I am looking forward to getting some form of teeth over the next month or so.
