The Alveolar Bone: Postnatal Delicate Tissue and Prenatal Sturdy Plasticity
With or without orthodontic treatment, the
alveolar bone is very fragile, delicate and prone to reduction in height,
when
a certain age has been reached by the individual. Skilled orthodontists
are
capable of gaining alveolar bone height by dexterous tooth movement.
In
other cases, it can be lost if we do it all wrong. Recent studies on
prenatal
formation of the early dental primordia, which are surrounded by fetal
alveolar
bone to form their sockets, showed the modality of their formation: It
is
a well interwoven interplay between resorption and apposition that leads
to
formation of the interdental and interradicular bony septa. The more
we
know about the processes that control formation of the alveolar bone,
the
more the chances rise to eventually transfer this knowledge to maintain
or
even to regain the bone of the alveolar crest in adults some time in
the future.
