Overdentures Supported by ITI Implants: A 6.5-Year Evaluation of Patient Satisfaction and Prosthetic Aftercare

This study reviews the long-term outcome of overdenture treatment in 64 completely edentulous patients who received 218 one-stage ITI implants during the period 1982 until 1988. The evaluation time averaged a period of 80 months, ranging from 66 to 119 months. The results indicate that no implants were lost during this period and that a minimum of surgical and prosthetic treatment was necessary to maintain the overdentures. Patient satisfaction was high and had not significantly changed in comparison with an earlier study on the same group of patients after a mean period of 18 months. The assumption that there would be significantly more complaints about retention of the maxillary denture is not affirmed by this study. Keywords: dental implants, overdentures, patient satisfaction
