Since, the introduction of the concept of osseointegration, the success of dental implants has increased dramatically because of better understanding of bone response and the improvement in bone loading concept. Improper patient selection, accumulation of bacterial plaque because of poor oral hygiene, traumatic occlusion, debris retention resulting from improper prosthetic restoration, and bone preparation without the use of internally cooled, high torque, slow speed hand pieces have been the factors contributing to the breakdown of otherwise successful implants.Predicting the adverse implant events and knowledge of treating the failing implants becomes mandatory for every clinician.Avoiding those conditions that contribute to poor results, choosing cases that offer ideal surgical and prosthetic circumstances and scrupulously evading complex clinical challenges can improve favorable outcome data substantially.
