Abstract
Osseointegrated implants have shown excellent clinical results, demonstrating their effectiveness in various medical applications. However, it is important to note that about 3-10% of these implants fail within a 10-year period. This highlights the need to understand the histologic response to reduce the incidence of implant loss over time. The aim of the present study was a histological analysis of the features of the tissues surrounding implant-failed titanium implants to try to understand the causal determinants. Dental titanium screw-shaped implants were removed for mobility. The implant had been placed in the jaw three months earlier. The implant was retrieved with a trephine. In the most coronal and apical parts of the implants, no mineralized tissues were present in contact with the dental implant. At low magnification, bone was observed at 200μ distance to the implant. In conclusion, the histological aspect of the dental implant suggests that overload may be the most likely cause of failure in the present case. However, we cannot be certain that it is the only possible cause in every case.
