Dental
implants are among the most successful procedures in dentistry. However, there
are no guarantees that an implant procedure will be successful. Given the complexity of the procedure, there
are many variables that can play into the success rate. The studies show a five-year success rate of
95 percent for lower jaw implants and 90 percent for upper jaw implants. The success rate for upper jaw implants is
lower because the upper jaw is less dense than the lower jaw, making the success
of implantation and osseointegration slightly more difficult to achieve. The lower posterior implantation has the
highest success rate for all dental implants
because of the density of the bone, there’s more to work with.
Other
factors that have an impact on success are pre-existing dental or general
health conditions or the position of the replaced tooth. Dental implants
may fail for a number of reasons, but the most come reason is the failure of
the implant device to properly osseo-integrate.
The actual failure of the implant may be the result of poor positioning
or over torqueing in the bone. Although
infrequent, dental implants may break or become infected or crowns may become
loose the same way your natural teeth become loose.
If you are
a heavy smoker, your dentist may advise you to give up smoking before
undergoing the procedure because smokers statistically face a higher risk of
implant failure. Given how expensive implants can be, one risks wasting money
on dental implants if you can’t give up the habit. Other high risk candidates
are patients with diabetes, hemophilia or immune deficiencies and rare
instances, patients with chronic bruxism.
As I have
noted in other articles the value of implants is significant with respect to
bone retention and actual functionality, and they are not susceptible to the
formation of cavities. So as long as one
engages in good oral hygiene, i.e. with brushing, flossing, and regular hygiene
procedures, the chances of peri-implantitis (characterized by inflammation or
swelling of the tissues surrounding the implant) should be avoidable. This disease is similar to periodontitis
around one natural tooth, and thus requires a similar approach to good oral
hygiene.
Key factors in
minimizing dental implant complications
are the selection of an experienced prosthodontist and oral surgeon who
specialize in implant dentistry, careful pre-operative treatment planning and proper
after-care and oral hygiene. If you
would like to know whether you are a candidate for implants please feel free to
call for a free consultation.
