Abstract:
Under normal physiological conditions, bone undergoes a
constant, balanced and well- regulated process of renewal
and remodelling. This is needed for growth, remodelling and
maintenance of skeletal form, as well as for homeostasis of
skeletal and plasma calcium levels. The alveolar bone grows
along with tooth eruption, and thereafter its shape and volume
are influenced by local mechanical as well as systemic factors.
It is maintained by forces exerted on it via the periodontal
ligaments, thus teeth are mandatory for its preservation and
renewal. Following tooth loss, the socket becomes filled with a
blood coagulum, which is later replaced by fibrous tissue. This
healing process is associated with sizeable reduction in ridge
height within the first two months that continues at a slower
and variable rate throughout life. There are countless examples
of patients who have lost teeth at an early age, presenting
with severe alveolar bone loss bone in that area / jaw. The extent
is even more dramatic if the edentulous space has been
opposed by natural teeth. The cases illustrated in this paper
serve to remind clinicians of the need to help patients maintain
as many of their natural teeth as possible, while still being
cognisant of their aesthetic and functional demands, and the
possible health implications.
