Étude en collaboration avec la clinique universitaire de Heidelberg : GalvoSurge vs AirFlow dans le traitement chirurgical péri-implantaire

The study will be carried out as part of the regular treatment of the pre-implantation on medical indication at the maxillo-facial surgery centers in Heidelberg or at the "Bella&Dent Hanau" dental clinic.

Qu'est-ce que la péri-implantite ?

Péri-implantite is a chronic inflammation of the implants which are firmly anchored in the ear. Inflammation leads to a loss of bone around the implant and, in the absence of treatment, loss of the implant. The disease is caused by bacteria that organize themselves in the form of a biofilm, particularly in the presence of risk factors such as tobacco use, diabetes and existing periodontal disease. The patient often does not notice this inflammation, but he may sometimes have symptoms at the level of the implant or minor pain/gonorrhea.

During dental examinations, however, this inflammation can be clearly demonstrated with the aid of various measured values. The aim of the therapy is to eliminate the biofilm and stop the inflammatory process. In addition to intensive hygiene measures, local rinsing with disinfectant solutions, surgical elimination of inflamed tissues and cleaning of the implant surface are always indicated in cases of pronounced implant failure. According to the current directive, this procedure consists of completely removing the inflamed tissues and cleaning the surface of the implant using instruments and a special device with a jet of powder.

However, current studies show that the long-term success rate of complete elimination of inflammation is only 58%, despite treatment conforming to the guidelines.

Comment se déroule l'étude ?

The study was carried out as part of the regular treatment of the pre-implantation on medical indication at the maxillo-facial surgery centers in Heidelberg or at the “Bella&Dent Hanau” clinic. It includes the relevé du résultat initial, l’intervention surgique elle-même ainsi qu’un total de quatre contrôles de suivi à 2 et 4 semaines, puis à 6 et 12 mois. The time and extent of the intervention correspond to normal treatment of the implant site.

As it is a “randomized study”, the patients are affected by hasard, either in group 1 (GalvoSurge – electrolytic cleaning method) or in group 2 (AirFlow – jet device) before the relevant initial results are obtained. The notification to the study group is communicated to the patients either at the end of the data collection or on request.

This latter case automatically entails the termination of the study, but does not present any inconvenience for patients.

What is the objective of the study?

The objective of this study is to compare the electrolytic cleaning process with a powder jet device in terms of their effectiveness for cleaning implant surfaces. During the electrolytic cleaning procedure, the exposed surfaces of the implant are bathed in an electrolytic solution and a minimum electrical voltage is generated on the implant via two small electrodes. Les bulles d’hydrogène qui se forment éliminent le biofilm. La machine à jet de poudre fonctionne avec de l’air comprimé et de la poudre contenant de la glycine. The exposed surface of the implant is thus irradiated in a circular manner and therefore cleaned.

The objective of the study is to determine which procedure allows to improve the nettoyage in the patient’s mouth and to eliminate post-implantation inflammation in the long term.

Comment puis-je participer à l'étude ?

If you would like to participate in this study, please contact the maxillo-facial surgery service in Heidelberg or the “Bella&Dent Hanau” clinic. Vous pourrez y obtenir des informations sur les conditions de participation et prendre rendez-vous pour un examen préliminaire. Please note that all patients are not automatically eligible for the study, as certain criteria must be met. Your doctor will inform you if you are eligible.

Your participation in this study can make a valuable contribution to the development of the treatment of the péri-implantite and may possibly be of benefit to you. If you have any other questions about the study or concerns about your participation, please do not hesitate to discuss them with your treating physician.
