Dental Implants
Background Information
Implants have revolutionized dentistry and are
changing people’s lives every day. Prior to the
advent of implants, when teeth were lost, our
options for replacement were very limited. Sometimes
a bridge could be placed, which utilizes adjacent
teeth to support the missing one. Sometimes the
only choice was to make a removable appliance,
a far from ideal restoration. Implants are small
titanium posts that are placed in the bone and
used as a foundation to support the missing teeth.
We no longer have to use other teeth to provide
support (thus compromising them), nor do we have
to rely on removable restorations. Implant supported
teeth look, feel, and function like normal teeth.
We use them for single tooth, multiple teeth,
and sometimes full upper and/or lower arch
restorations.
The Process
The first step in implant treatment is a consultation
with us. We will perform a clinical examination
and if necessary take some digital radiographs
to determine if implants are indicated. Sometimes
further imaging such as a CT scan is recommended
and we will arrange for this as well. Implant restorations
have three parts. There is the fixture which is
the part that is placed in the bone. There is an
abutment (or a post) which attaches to the fixture
and supports the restoration. Finally, there is
the restoration which may be a single crown, an
implant supported bridge, or some type of implant
overdenture.
Implants are restoratively driven. This means that
the placement and the position of the implants
are determined by the final restorations. The fixtures
will be placed by an oral surgeon or a periodontist
but it is important to first have a game plan in
mind. Where should the implants be placed? How
many implants are needed? What is the sequence
of treatment and how will the patient be temporized
(if necessary) until the final work is completed?
These are some of the questions that are discussed
at the first visit.
Once we have a treatment plan finalized, the implants
are placed. In complicated cases, we will provide
the surgeon with a surgical guide to insure ideal
placement. The implants will generally not be restored
for 2 – 4 months while the bone is growing tightly
around the fixtures. This process is called osseointegration.
After this waiting period, we can proceed to the
final restoration. This step involves taking impressions,
bite registrations and shade selection. Digital
photography has aided us in expediting this process
and enabled us to communicate better with our technicians
to ensure a beautiful final result.
