What is a common characteristic of a failure in osseointegration?

A common characteristic of a failure in osseointegration is sustained micromovement. This phenomenon occurs when an implant does not properly bond with the surrounding bone, resulting in relative movement between the implant and the bone interface. In a successful osseointegration process, the bone integrates with the implant surface, providing a stable environment for the implant to function effectively without any excessive movement.

When there is sustained micromovement, it can lead to the disruption of the bone healing process, preventing the formation of a stable mechanical bond and increasing the risk of implant failure. This instability can provoke inflammation and bone resorption, further complicating the healing process.

Other options, such as immediate integration, rapid formation of bone, and consistent implant stability, do not typically indicate a failure in osseointegration. Immediate integration would imply that the implant has successfully connected with the bone right after placement, while rapid formation of bone could indicate a positive healing response. Consistent implant stability suggests that the integration has occurred properly and there are no issues with the bond between the implant and the bone.
