Purpose: To evaluate the success and failure rates over time of ITI implants placed in 3 private practices and used in a variety of clinical situations. Materials and Methods: ITI solid-screw implants (n = 5,526) were placed in 3 private practices and restored by a variety of clinicians. Numerous clinical scenarios were treated with the implants, which were in function for between 0 and 72+ months. Results: After 72+ months the cumulative success rates were 94.8% for maxillary implants and 97.5% for mandibular implants. The overall cumulative implant success rate was 96.1%. Implants that failed to osseointegrate were included in the data as failures in the 0- to 12-month interval. The criteria of Albrektsson and associates were used to assess implant success or failure. Discussion: The results, which were achieved in conjunction with numerous restorative clinicians, were comparable to those reported by other authors. The clinical viability of ITI implant use was thus reinforced. Conclusion: ITI solid-screw implants were a predictable treatment modality in 3 private practices for a variety of clinical applications.
