Implant failure is most likely the result of multiple factors. Age and sex, smoking, systemic diseases, maxillary implant site, quantity and quality of bone, and implant surface treatments and features are some of the statistically examined parameters linked to implant failure. Dental implant failure is classified as early and late implant failure. Early implant failure means an implant showing clinical mobility before the placement of a final prosthesis. This is usually because of biological problems where the body does not accept the implant. It is called "rejection" of the dental implant. Early implant failure may be linked to immunological, genetic, and immunological variables. Late implant failure occurs within 1-3 years after the placement of the implant.
