When we visualize the longitudinal image of our jawbone, it seems to be continuous and homogeneous irrespective of the part where teeth grow and the principal body of jawbone. However, the part with teeth is called as alveolar bone, which is derived from the periodontal membrane on the surface of teeth, embriologically different from our jawbone.
Therefore, the teeth with infected surface by alveolar pyorrhea and with necroses of all the periodontal membrane cells cannot be recovered to the previous status.
However, if the teeth with firmly retained periodontal membrane cells are implanted to the extracted space whereby the said teeth produce the bone by activities of their periodontal membrane cells and successfully bind with the bone.
As previously explained, the periodontal membrane possess lots of well-developed sensory receptors within it, which contribute to transmission of information to the brain. It seems to us that this periodontal membrane plays a key role in providing organic lives to teeth.
Of interest to note, this periodontal membrane only exists in mammals in the evolution stages.
