Summary
This study found that 7% of porous oxide-surfaced (TiUnite) implants failed. Failing implants showed significant bone loss, unlike successful ones.
Area of Science:
- Dental Implantology
- Biomaterials Science
Background:
- Porous oxide-coated implants (TiUnite) are used in dental restorations.
- Assessing implant survival and bone changes is crucial for long-term success.
Purpose of the Study:
- To evaluate implant survival rates and crestal bone changes for porous oxide-coated (TiUnite) implants.
- To identify factors influencing implant failure and bone loss.
Main Methods:
- Prospective study of 817 TiUnite implants in 409 patients.
- Survival rates calculated from placement date; factors analyzed included surgical method, bone quality, and implant characteristics.
- Crestal bone levels and radiographic shadows compared between failing and non-failing implants.
Main Results:
- Cumulative survival rate was 93% over the study period.
- Implant failure rate was independent of bone quality, quantity, or surgical method.
- Failing implants exhibited significant mean crestal bone loss (-4.14 mm), while surviving implants showed minimal change (+0.13 mm).
Conclusions:
- Approximately 7% of TiUnite implants failed due to unknown reasons.
- Significant crestal bone loss is a key characteristic of failing TiUnite implants.
- Radiographic shadows around the implant apex did not predict failure.
