One of the many reasons for dental implant popularity is their reliability — studies have shown 95% of implants still function well after ten years. Still, on rare occasions an implant will fail. We can minimize this risk by taking precautions before, during and after installation.
Long-term success begins with careful planning before surgery. We thoroughly examine your teeth and jaws, using x-rays or CT scanning to map out the exact location of nerves, sinus cavities and other anatomical structures. Along with your medical history, this data will help us develop a precise guide to use during implant surgery.
We’ll also assess bone quality at the intended implant site. The implant needs an adequate amount of bone for support — without it the implant will not be able to withstand the biting force of normal chewing. It may be possible in some cases to use bone grafting or similar techniques to stimulate growth at the site, but sometimes other restoration options may need to be considered.
The surgery can also impact future reliability. By precisely following the surgical guide developed during the planning stage, the oral surgeon can increase the chances of success. Still, there may be an unseen variable in play — a pre-existing or post-operative infection, for example, that interferes with the integration of the implant with the bone. By carefully monitoring the healing process, we can detect if this has taken place; if so, the implant is removed, the area cleansed and the implant (or a wider implant) re-installed.
Even if all goes well with the implantation, there’s still a chance of future failure due to gum disease. Caused mainly by bacterial plaque, gum disease infects and inflames the supporting tissues around the teeth; in the case of implants it could eventually infect and weaken the surrounding bone, a condition known as peri-implantitis. This calls for aggressive treatment, including plaque and infected tissue removal, and possible surgery to repair the bone’s attachment to the implant. Without treatment, the implant could eventually detach from the weakened bone.
Maintaining your implants with good oral hygiene and regular dental checkups is the best insurance for long-term reliability. Taking care of them as you would natural teeth will help ensure a long, happy life for your “third set” of teeth.
