What causes “rejection” of a dental implant?

It´s normal to have someone we know tell us that their body has rejected a dental implant. It´s important to mention that the body´s “rejection” of the dental implant isn´t actually the correct term. The implant isn’t rejected by our body, as can be the case with an organ transplant where the immune system rejects the donated organ. The correct term would in fact be the “failure” of a dental implant.

On many occasions, we find ourselves asking, what causes a dental implant to fail? The failure of an implant can be linked to a number of different factors, which negatively affect the duration and effectiveness of the implants. Of these, the three most common are infections, the surgeon´s knowledge or experience and the overloading of the implants because of teeth clenching.

Infection occurs in 1-2% of cases, regardless of whether or not the treatment has been done correctly. Over the years, this percentage could increase considerably if the patient has a form of gum disease such as periodontitis or pyorrhea which has been left untreated, or if they don´t maintain a good level of oral hygiene at home. It is therefore important to ensure good habits when it comes to looking after dental implants.

Another way in which rejection of dental implants can be avoided is the choice of surgeon, their experience and knowledge, as well as the use of 3D technology. The 3D scanner enables the surgeon to have an accurate view of the maxillary bone, ultimately reducing complications that may increase the risk of failure of the dental implant.

The premature rejection of dental implants tends to occur due to habits such as bruxism, or teeth clenching at night, which subject the implants to excessive force and therefore cause them to fail.

There are many advantages of having good dental implants and it´s therefore important to choose a centre with professionals who have a wide-range of experience and knowledge about Implant Dentistry, as well as having access to 3D technology and surgical microscopes, which reduce the chance of implant failure. All of these elements will enable us to enjoy a healthy mouth, for longer.
