Which of the following is a characteristic of an effective dental implant?

An effective dental implant is characterized by successful integration with bone, a process known as osseointegration. This means that after the implant is placed, it forms a strong and stable bond with the surrounding jawbone, providing a solid foundation for the artificial tooth. This integration is vital for the longevity and functionality of the implant, allowing it to withstand the forces involved in chewing and restoring normal functionality of the mouth.

In contrast, immediate removal after placement, instability during chewing, and the need for frequent replacement indicate issues rather than characteristics of a successful implant. Such problems would undermine the overall success of the implant, leading to complications and potential failure. Thus, successful integration with bone is the hallmark of an effective dental implant.
