Tooth loss is very common in patients, regardless of age.

In some circumstances it is due to accidents, blows, dental caries or gum disease.

This dental loss can be total or partial, however, regardless of the number of teeth lost, it is essential to think about their fixed replacement, by means of dental implants or dental bridges.

Dental implants are attachments made of an alloy of metals, including titanium, which provides the particularity of being compatible with the human bone, allowing a process of integration to the tooth.

Once they have been placed, the osseointegration process takes 6 to 8 months and then rehabilitation is carried out by means of dental crowns, which can be made of porcelain metal, zirconium or complete porcelain crowns.

The success rate of dental implants is 90 - 95 %. But for what reasons can a dental implant be lost?

When patients opt for dental implant rehabilitation they usually have a normal healing process, however in some cases complications occur that can lead to implant failure.

When this implant loss occurs before six months after placement, it may be due to bone quality, risk factors or systemic diseases.

When dental implants fail seven months after placement and restoration, in most cases it is associated with peri-implantitis.

Peri-implantitis is an inflammatory process that affects the tissues surrounding the dental implant, causing the loss of support of the bone in which it is integrated.

Clinical signs may include reddening of the gum around the implant, bleeding that may be accompanied by suppuration, pain on percussion and mobility of the implant.

It is important to always verify with a CT scan.

The main causes that can cause periimpantitis are bacterial plaque that accumulates on the surface of the dental pieces that can also be located on the surface of the implant, occlusal overload, which is nothing more than the excessive force applied by the antagonist teeth to the dental implant. In other cases, tobacco consumption, bone quality in general and deficient oral hygiene can also contribute.

When this type of rehabilitation is performed, it is important to take into account that the patient must continue to attend follow-up appointments for cleanings, x-rays and to follow up the case so that the restoration is kept in the mouth in an optimal manner.
