Epidemiology of periimplantitis is topic of the third part of the lecture series of Professor Stefan Renvert, University of Kristianstad/Sweden, held on the EDA Early Dental Workshop. He presents data of his own patient population. This patient population consists of nearly 300 patients, provided with in total 999 implants between 1988 and 1992.
The rate of implant losses in the following nine to 14 years of recall was rather small. It raised especially in patients who suffered from periodontal diseases before, so a loss of more than one implant was observed. In total every 10. patient had lost at least one implant over those years. The prevalence of periimplantitis was 16 %.
