You can call an implantological concept a success in case the failure rate is below 1 % in the first ten years after implantation. Today it is not the osseointegration which is the most important risk factor, but the single materials coming across in an implant system.
Dr. Jan Hajtó, Munich/Germany, describes typical today's failures in implantology and their reason. On this basis he develops a problem-dissolving approach for optimization of implantological concepts.
