Dental implant failure has led to continuous innovations of various
implants systems and to different interceptive treatment modalities.
These concerns have also led to selection of implant designs that best
suit the various types of bone. There are a variety of reasons for the
failure of endosseous implants. Different reasons for the implant
failure and their contributing factors have been discussed. The various
studies done on each of these failures and how to prevent these failures
have been discussed too. Failure of implants has a multifactorial
dimension. Often many factors come together to cause the ultimate
failure of the implant. One needs to identify the cause not just to
treat the present condition but also as a learning experience for future
treatments. Proper data collection, patient feedback, and accurate
diagnostic tool will help point out the reason for failure. An early
intervention is always possible if regular check-ups are undertaken.
