Periimplantitis belongs to the common complications during implantoprosthetic treatment. One of the main reason is the accumulation of plaque around the abutment. The consequences are the inflammation, the bone loss around the implant and the final loss of the implant. In 2010, Dr. Awillo developed a method involving the use of biocompatible properties of zirconia. In vitro studies were conducted for two years, with the Department of Mikrobioanalytics of the University of Warsaw. These studies showed a high adaptive capacity of connective tissue cells fibroblasts to the surface of zirconia. Schlagwörter: periimplantitis, hybrid abutments, implantology
