In the edentulous the jaw bone usually shrinks over time. Is it
because of (1) aging, (2) poor nutrition, such as low vit D levels,
smoking, low calcium levels, or (3) lack of teeth.
This shrinking is unpredictable.
Why should it be related to lack of teeth? Should it be related to
lack of PDL? or lack of stimulation? Why will implants help?
The entire field of orthodontics is based on the selective resorption and deposition of bone by controlled means of applied force through the PDL. As for implants, I'm not familiar with the science involved. I know that way back in school the hypothesis was that piezoelectric effects were involved. However, implants have been around long enough (to say nothing of experience with root-borne overdentures) to pretty conclusively demonstrate that (no matter how it happens) functional stimulation of the alveolar bone is preservative.

Maybe what we call periodontal disease is really a disease of aging
since the jaw bone naturally shrinks with age.
