The classical prosthesis is supported by the gums and cannot bring
about the continuous reconstruction of the bone that nature had designed.
The bones of the jaw are reabsorbed and breakdown progressively. This
bone loss can bring about a state of unbalance which provokes tension
and abnormal loosening of the muscles of the face and neck. This explains
the gradual onset of facial and cervical pain. It is the reason for
which toothless persons seem to age more rapidly than others. Their
lips sink in and their chins are pushed up towards the nose causing
the loss of muscle tone required to maintain the delicate balance
of the facial morphology. Partial prostheses can also bring about
damage: the same phenomenon of bone degradation occurs depriving the
adjacent teeth of their support. The movement of the partial during
mastication ends up affecting the adjacent teeth and in the long term
can cause their degradation and loss.
