Abstract: Osseo integrated dental implants have been considered the most esthetical and functional alternative to missing teeth. However, the treatment is not always successful resulting in the implant loss. The implant failure can be classified as early failure (the Osseo integration is not established) and late failure (involving a breakdown of the established Osseo integration). The implant loss can be attributed to factors such as biological, microbiological and biomechanical, but the cause and mechanism of the early implant failure are still obscure. 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 end osseous implants. Different reasons for the implant failure and their contributing factors have been discussed in the review article.
