Bone Augmentation Treatment
A dental implant is an artificial
tooth root replacement that is placed into your jaw to hold a replacement tooth
or bridge. Dental implants are often performed for those who have lost a tooth
or teeth due to periodontal disease, an injury, or some other reason.
However, for dental implants to
be successful, the jawbone must have enough bone to support them. If there is
loss of bone due to periodontal (gum) disease, injury or trauma, or a
developmental defect among other reasons you will need an additional procedure
to add bone to your jaw before implants can be placed.
The term used to describe the
variety of procedures that are used to "build" bone is bone augmentation.
The procedure involves grafting bone or bonelike materials to the jaw. Several
different procedures can be used for bone augmentation. Your dentist will
select a procedure depending on the type, location and number of implants to be
used.
Bone augmentation procedures
typically involve the use of bone grafts. The best material for a bone graft is
your own bone, though there are other options available to you.
In a typical situation, a patient
who has lost a single tooth and wants to have it replaced with a crown
supported by a dental implant. However, the tooth has been missing for several
years and there is not enough bone to support the implant. In this case, bone
taken from the patient's chin can be used to "rebuild" the lost bone
so that it can support an implant. This type of procedure would be done in a
dentist's office.
Another type of bone-augmentation
procedure is called a sinus lift or elevation. It increases the height of your
upper jaw by filling part of the area above your jaw on either side of your
nose with bone. This is done when there is not enough bone to allow implants to
be placed in the back part of the upper jaw.
A ridge expansion is a type of bone graft that can be
done when the jaw is not wide enough to support
implants. The success rate for
bone grafts in the jaws is very high and over the years, most dentists will
place
implants directly after this procedure. This procedure can be done in the
dental office under local anesthesia.
