| A
natural tooth consists of a crown (the part you see above the gum),
and the root (the part hidden under the gum, within the jawbone).
It is the root that actually holds the natural tooth in place.
When
a person is missing a tooth, the dentist must decide how to re-create
the crown portion, and he must choose the best method to hold it
in place. Dental implants were created for this purpose.
Dental
implants are metallic cylinders that are placed into the jawbone
where original teeth once existed. These root-like cylinders are
used to secure a replacement tooth in place in a spot where a tooth
is missing. Dental implants can also be used to secure loose teeth
in place by being installed alongside the loose teeth and anchoring
to them with splinted crowns. This will allow the loose teeth to
function better and last longer in the mouth.
Dental
implants are made of various biomaterials. Most commonly, a surgical
metal called titanium is used, because it is the most compatible
with human biology. They are surgically placed in the jawbone, right
in the dentist¡¯s office, using a local anesthetic. Approved and
tested implant systems are very successful. In fact, some have lasted
more than 20 years with a better than 90% success rate. Patients
who have good oral hygiene and take care of their new teeth can
enjoy implants that last a lifetime.
