An implant-supported restoration offers a predictable treatment for tooth replacement. There is high success rate regarding the implant placement except in medically compromised patients. Nevertheless, there are pros and cons related to everything and similar are the case with the implants and the burning problem that all the implantologists are confronted today is the complications and failures occurring with the treatment of osseo-integrated implants. The surgical trauma with bone volume and quality are generally believed to be most important etiological factors for early implant failures and the etiology of late failure is more controversial and thus when an implant fails a tailor may treatment plan should be provided to each patient according to all relevant variables and patients should be informed of regarding all possible treatment modalities following implant failure and give their consent to the most appropriate treatment option for them. Thus the aim of this paper is to explain different methods and treatment modalities to affect implant failure.
