What is a differential diagnosis for implant failure?

The correct choice highlights that both mechanical issues and peri-implant diseases are significant considerations in diagnosing implant failure. Mechanical issues can arise from factors related to the implant design, placement, and occlusal forces that may lead to complications like screw loosening or fractures. On the other hand, peri-implant diseases, which include peri-implantitis (inflammatory conditions affecting the gums and bone around the implant), can also contribute to implant failure by causing loss of supporting bone and compromising the stability of the implant.

In clinical practice, a comprehensive approach to diagnosing implant failure involves evaluating a combination of mechanical factors and biological responses, such as infection or inflammation. This holistic view is essential for effective management and treatment planning, as it allows practitioners to address not just the surgical considerations but also the biological health of the peri-implant tissues. The interplay between these factors is vital for understanding the overall health of the implant and ensuring long-term success in implant therapy.

Considering this, focusing solely on mechanical issues, immobility, or patient compliance factors would limit the understanding of complex reasons behind implant failure and neglect important areas that need to be assessed for proper diagnosis and intervention.
