Bone
Grafting
A bone graft is a surgical
procedure that replaces missing bone with material from your own
body (autogenous bone) or an artificial, synthetic, or natural
substitute.
A bone graft not only replaces missing bone, but also helps your
body to regrow its own lost bone. This new bone growth strengthens
the grafted area by forming a bridge between your existing bone
and the graft material.
Over time your own newly
formed bone will replace much of the grafted material.
Bone grafts may be needed
when part of your body is missing bone. This missing portion of
bone is frequently called a “bony defect”. Examples of jawbone
defects are: defects which occur following tooth extraction; generalized
decrease in the quantity of jawbone from trauma or long-term tooth
loss; defects surrounding "old style" dental implants;
defects resulting from cysts or tumor surgery.
Why
is a bone graft needed?
Bone grafting is performed
to reverse the bone loss / destruction caused by periodontal disease,
trauma, or ill fitting removable dentures. It is also used to
augment bone to permit implant placement, such as augmenting bone
in the sinus area for implant placement, or augmenting bone to
enhance the fit and comfort of removable prostheses, or to enhance
esthetics of a missing tooth site in the smile zone. When one
loses a tooth, as in an extraction, the surrounding bone collapses.
To preserve this bone for future implant placement or for esthetics,
a bone graft is used.
What are
the types of bone graft?
1. autogenous - bone taken
from one area of the patient and transplanted to another area
requiring such grafting
2. allograft - either synthetic bone or bone from a bone bank
(cadaver bone)
3. xenograft - bovine /cow bone
Which
graft is used and when and why?
Autogenous bone is the
"gold standard" and oftentimes has the most predictable
results. This is described as the best type of graft because such
bone is live bone with live active cellular elements that enhance
bone growth, whereas other types of grafts are devoid of any active
cellular material.
Allografts and Xenografts
both do not require a second surgical site as does the autogenous
bone. Ample amounts can be easily obtained.
Barrier
membranes
In conjunction with bone
grafting, membranes are often used to help stabilize the bone
graft as well as displace the gum tissue from invading the healing
bone graft. Gum tissue grows at a much faster rate than bone,
therefore, membranes are used to prevent gum tissue from growing
in and displacing the bone graft before it matures.

Guided Tissue Bone Regeneration.........
Missing bone and
tissue can be restored to create a solid foundation for your beautiful
smile.
Today we are able
to restore or regenerate missing bone and attachment around teeth
subjected to long-standing periodontal disease or trauma. If you
have lost a tooth due to trauma or disease, we can restore or
regenerate bone prior to the placement of bridges or dental implants.
These methods
are referred to as Guided Bone Regeneration and Guided Tissue
Regeneration. The procedures attempt to regenerate lost periodontal
structures, lost bone, periodontal ligaments, and connective tissue
attachment that supports your teeth. This is accomplished using
biocompatible membranes, bone grafts and/or tissue stimulating
proteins. These procedures are common prior to or in conjunction
with the placement of dental implants.
Guided Bone Regeneration
and Guided Tissue Regeneration procedures have allowed millions
of people to restore health to diseased teeth which would have
been condemned to extraction in the past.
If you have lost
teeth, these remarkable therapies have given clients a second
chance to enjoy the benefits of "permanent teeth" with
the help of dental implant reconstruction. You will experience
an enhanced quality of life as a direct result of improved health,
function and appearance.
Bone heals more
slowly than the gum tissues in your mouth. Guided Bone Regeneration
allows the bone to maximize its full healing potential following
surgical procedures.
The treatment
is simple. A biocompatible membrane is placed between the gum
and bone which acts as a barrier. This barrier prevents the growth
of the gum tissue from limiting the growth of the underlying bone
as it heals.
Membranes around
teeth are typically designed to dissolve away, or reabsorb, after
several weeks of healing have passed. Some membranes used to restore
bony ridges in association with bone implant therapy are not absorbable
and must be removed.
Bone Grafts
A bone graft is a surgical
procedure that replaces missing bone with material from your own
body (autogenous bone) or an artificial, synthetic, or natural
substitute.
A bone graft not only replaces missing bone, but also helps your
body to regrow its own lost bone. This new bone growth strengthens
the grafted area by forming a bridge between your existing bone
and the graft material.
Over time your own newly
formed bone will replace much of the grafted material.
Bone grafts may be needed
when part of your body is missing bone. This missing portion of
bone is frequently called a “bony defect”. Examples of jawbone
defects are: defects which occur following tooth extraction; generalized
decrease in the quantity of jawbone from trauma or long-term tooth
loss; defects surrounding "old style" dental implants;
defects resulting from cysts or tumor surgery.

Regrowing
Your Lost Bone:
Guided Tissue and Bone
Regeneration
In the past, the treatment
of periodontal (gum) disease was considered to be painful and
disfiguring. For many years, the best way to achieve the ultimate
goal of therapy (shallow, maintainable pockets) was to do resective
surgical procedures that often resulted in the exposure of sensitive
root surfaces and the appearance of "long" teeth.
Today, periodontists are
often able to restore or regenerate missing bone and attachment
around teeth subjected to long-standing periodontal disease. In
addition, if you have lost a tooth due to trauma or disease, we
can restore or regenerate bone prior to the placement of bridges
or implants.
Guided tissue regeneration
(GTR) refers to procedures that attempt to regenerate lost periodontal
structures (bone, periodontal ligament, and connective tissue
attachment) that support our teeth. This is accomplished using
biocompatible membranes, often in combination with bone grafts
and/or tissue stimulating proteins.
Guided Bone regeneration
(GBR) refers to procedures that attempt to regenerate bone prior
to the placement of bridges and implants. This is accomplished
using bone grafts and biocompatible membranes that keep out tissue
and allow the bone to grow.

Frenectomy
A frenum is a fold of tissue
or muscle connecting the lips, cheek or tongue to the jawbone.
A frenectomy is the removal of one of these folds of tissue.
Sometimes a frenum can
be attached too high on the gums causing either recession or spaces
between teeth. The procedure to remove this is a called labial
frenectomy and involves the removal of tissue attachment between
the two front teeth as the gap between the teeth can again pushed
apart by the frenum, even after it being initially corrected via
a different procedure. The frenum can be attached in such a way
that it prevents the baby teeth from coming through.
A lingual frenectomy removes
the fold of tissue under the tongue. Some people have a large
frenum that limits tongue movement and can interfere with speech.
The condition of limited
tongue mobility is called ankyloglossia, or tongue tie.
Tongue-tie is generally
diagnosed in childhood and symptoms include:
- Interference with feeding
in infants. Problems with speech at 12 to 18 months.
- Some older children
or teenagers may notice that the frenum under their tongue becomes
stuck between their front teeth, or that they can't stick their
tongue out as far as their friends can.
- Adults receiving dentures
may need a frenectomy if the position of a frenum (usually one
between the cheek and gum in the back of the mouth, or in the
middle of the upper or lower lip) will interferewith the proper
fit of the denture.
Before recommending a frenectomy
in a child, a dentist will consider several factors, including
the probability that the condition eventually will resolve itself
without surgery.
If a child has tongue-tie,
he or she will receive speech therapy first to see if that can
correct the problem. The therapy will involve special exercises
to increase the tongue's mobility.
To complete a frenectomy,
a surgeon can use a scalpel or a laser. A laser minimizes bleeding,
reduces the need for sutures and causes less postoperative pain.
If a scalpel is used sutures will be needed after surgery.
People receiving a laser frenectomy must remain completely still
during the operation, so younger children may require general
anesthesia. In older children and adults, the procedure can be
done with local anesthesia, with or without nitrous oxide. The
surgery itself takes very little time, and can be completed in
as little as 10 to 15 minutes.
A frenectomy can take several
weeks to heal completely. Rinsing with salt water helps keep the
area clean. Brush and floss carefully around the area. Depending
on the type of stitches your dentist uses, you may need to return
to the dentist to have your stitches removed or they may dissolve
on their own.
If the operation does not
solve the problem, it may need to be redone. Redoing a lingual
frenectomy is somewhat common. Few labial frenectomies need repeating.
Any surgery carries a risk
of bleeding. Because of the many blood vessels in the tongue,
lingual frenectomies are more likely to result in bleeding, although
this complication is quite rare.
In adults receiving a frenectomy in the lower jaw to correct the
fit of dentures, there is a risk of bruising the nerve that provides
sensation to the lower lip and chin. This will cause numbness
in the area that can last at some level for several months. However,
your lip will not droop, as the nerve does not affect movement,
only sensation.
