Are you curious about bone grafts?
Most dental bone grafting procedures are
done to restore your bone to its previous form
following tooth loss, gum disease or trauma.
Bone grafting may also be used to maintain
bone structure after tooth extraction.
Restoring and maintaining facial bone
structure is important for several reasons.
Many dental procedures, such as
dental implant placement,
require that the bone be as close to
its original dimension and position as
possible for optimal results. Also,
the jaw and other facial bones support
the skin and muscle that are responsible for
our outward cosmetic appearance.
Without the support of the underlying bone,
our faces can look prematurely aged.
where does bone grafting material come from?
Bone grafting material comes
from several sources.
1. Autograft
Autograft bone is material that is taken
from another point in the patient's body
and transplanted to the desired site.
It is a good graft material since it
contains the patient's own cells, and carries
no risk of disease transmission.
The chief drawbacks are that it
requires a second
surgical procedures and enough
harvestable bone
that may not be easily available.
2,. Allografts
Allograft bone is material that was taken from
an organ donor and processed to
ensure its safety and improve the handling
characteristics. The advantages of allograft
bone are that it is readily available and
does not require a second surgical site.
Allograft bone has been well
documented in clinical trials and has an
excellent safety record.
3. Xenograft
Xenogratfs are bone grafts from a species
Other than human, such as bovine and are
used as a calcified matrix.
Using bovine bone (cow bone) as a graft
material has become commonplace in most
oral surgical offices today and has been
a tried and proven technique for many years.
A simplified explanation for the success of
this form of grafting is that a bovine bone
graft is placed to act as a
“biological placeholder.” Initially,
it mechanically prevents the collapse
of the surrounding tissues,
whether that is bone or soft tissue.
Then, through a process called
“guided tissue regeneration,”
the human body is fooled biochemically to
recognize the graft as natural bone and
over time resorbs and replaces it with
the patient’s own native bone.
4. Alloplastic grafts
Alloplastic grafts may be made from
hydroxyapatite, a naturally occurring mineral
(main mineral component of bone),
made from bioactive glass.
Hydroxyapatite is a synthetic bone graft,
which is the most used now due to its
osteoconduction, hardness, and acceptability
by bone. Some synthetic bone grafts are
made of calcium carbonate,
which start to decrease in usage because
it is completely resorbable in short time and
makes breaking of the bone easier. Finally
used is the tricalcium phosphate in
combination with hydroxyapatite and
thus giving effect of both,
osteoconduction and resorbability.
The main use of bone grafting in
dental implants, this procedure is used to
fuse joints to prevent movement,
repair broken bones that have bone loss,
and repair broken bone that has not yet
healed.
