How Clean is Your Implant? Why the Long Term Success of Your Dental Implant Therapy is in Danger.
The surface of dental implants determines the initial phases of the biological response to the implant and affects its ability to integrate into the surrounding tissue. In four consecutive studies since 2007 more than 250 different, sterile packaged dental implants were analyzed by scanning electron microscopy and EDS for an appropriate elemental analysis. Depending on the manufacturing and packaging processes, the studies revealed a wide variety of avoidable organic and/or inorganic contaminations on sterile implants. Participants of this lecture will see numerous dental implants with massive organic pollution and inorganic particles containing iron, copper, chromium, tungsten and nickel. Recent ToF-SIMS analyses revealed even hazardous substances such as Dodecylbenzene sulfonic acid. The lecture separates the wheat from the chaff and gives precise information about the possible clinical impact of impurities and the level of quality that is technically possible. Inferior quality products are flooding the implant market. It is time to wake up and to critically question the choice for a dental implant in order to protect not only the long-term success of dental implant therapy but also protect every patient.
