Experienced dentists, who have worked with dental implants, crowns and fixed prosthesis, will be aware that, when well looked after, they can last for a lifetime. Restorations will often look as good as they first did when they were placed on dental implants. However, sometimes the implants show radiographic signs of advancing
When dental implants first came on the scene, many dentists believed that they would be replacements for teeth as good as the real thing. A decade after the first dental implants hit the market, dentists started to see exceptions to this idea, with degenerating bones exposing the implant surface as a result of what we now know to be peri-implantitis. Some dentists failed so badly they had to be removed. These failures falsified the 95% success rate that studies into dental implants had first reported. In a few situations, we know why dental implants fail, but in many more, we simply do not know. This does not bring into question the good that dental implants do. It does, however, show that dental implants are not perfect solutions.
There are a few reasons that scholarship has identified for dental implant failure.
Firstly, some people experience allergy to the metals used in dental implants. A small subset of the population is allergic to aluminum, titanium and vanadium.
Another reason why dental implants fail is due to improper or excessive occlusion. About a third of patients suffer from

That is not the case. A dentist has to ensure that their patient does not have any prior periodontal disease before they place implants.
