Dental implants: contraindications

IMI Clinic

How to assess and evaluate a dental implant intervention

Implantology techniques are finding constant success because of their immediate and long lasting aesthetic and functional results. However, just as any other kind of surgery, even implantology techniques can bring some contraindications that an implantology surgeon must always consider before carrying out the intervention.

Namely, a doctor must keep in mind the patient’s basic clinical condition, and evaluate the relationship between risks and benefits.

All healthy individuals can undergo the surgery without particular problems or contraindications, and can opt for an innovative, minimally invasive, quick and effective method, which will restore dentition both from an aesthetic and a functional standpoint.

The most important and severe contraindications for dental implants, instead, mainly concern a series of pathological conditions that, besides potentially nullifying the result of the surgery itself, may also compromise healing and duration.

Dental implants, pathologies and systemic diseases

dental-implants-contraindicationsSystemic diseases that interfere with the regular process of cicatrisation and blood coagulation, cardio circulatory and immune system alterations, as well as mental states that can twist the perception of ones image, are the main deterrents for an implant surgery.

More specifically: hepatitis, severe psychological disorders, kidney insufficiency, immunodeficiency, neurological diseases, subjects that have undergone chemotherapy and drug addicts, do not represent ideal patients for dental implants interventions.

In some cases, regardless of important systemic pathologies, the implant surgery can still be taken into consideration, but only after having carefully analysed specific physiological parameters. In the case of diabetes, for example, a stabilisation of glycaemia could make it possible to resort to dental implants, by checking the regularity of cicatrisation.

Another very important contraindication is osteoporosis, a pathological condition in which bone tissue loses its natural consistency, which makes a potential osseointegration process inefficient and incomplete, and, besides, could also cause a potential osteonecrosis due to the pharmaceuticals taken.

Way less severe contraindications, instead, include the scarce presence of residual bone (as it is possible to pre-emptively carry out bone regeneration), an on-going pregnancy (since it excludes a patient just for the gestational period), and tobacco consumption (since smoking slows down the healing process). Finally, albeit age does not actually represent a contraindication, it is better not to intervene on minors, since the bone growth of these patients is not yet complete.

Even if patients who appear to be in a healthy state are not exposed to all these potential risks, it is still important they maintain a careful post-implantology behaviour.

The long-lasting and successful guarantee of implants is, in fact, ensured by a correct and constant dental hygiene, by a reduction in alcohol and cigarette consumption, and by committing to undergo periodical dental check-ups, which can spot any possible critical situations.
