Abstract
Purpose: The purpose of this study was to determine the success of IMZ implants after prosthodontic rehabilitation.
Patients and Methods: A prospective study analysis was made of the treatment results for 541 patients after the insertion of a total of 1,250 IMZ implants at 2 practicing dentists' offices over a period of 13 years. The most frequent treatment situations were insertion in the totally edentulous lower jaw (44.1%) and in a distal edentulous region (37.6%). The statistical survival rate assessment was made using Kaplan-Meier survival analysis. The results were compared with the cumulative survival rates for all implants during a period of 10 years.
Results: At 5 years after insertion, 96.0% of all implants were in situ and noninflamed; after 10 years, the survival rate was 82.4%. For both the upper and the lower jaw, better results were recorded in the posterior part of the jaw than in the anterior part.
Conclusions: The IMZ implant system showed a good 10-year-survival rate. ¨© 2003 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 61:691-695, 2003
