Implant dentistry is a successful way to replace missing teeth. The purpose of this study was to retrospectively assess the rate of implant survival in a graduate clinic and to relate the findings to the health of patients. The charts of 133 patients who received implants at the School of Dental Medicine at the University at Buffalo were randomly selected and reviewed. In all, 302 implants had been placed. The age of the patients ranged from 18 to 86 years. Of these, 111 were medically compromised (83.5%) and included active and former smokers. Eight implants failed, resulting in a 97.5% implant survival. The rate of implant success in a teaching setting is high considering that the majority of subjects presented with medical conditions.
