The dental implants in modern dentistry brought out a new era in everyday dental practice. Increasing of dental implants usage, various failures and complications has occurred. Failures and complications of dental implant treatments that can happen in implant surgery, in mechanical or prosthetic problem and in biological aspect. The aim of this study was to assess implant failures for 6 years as well as find out how to overcome implant failure. In Jeju National University hospital, 26 dental implants in 17 patients were removed by implant failure through 2013.1.1.―2018.12.31. Each implant failure case was analyzed in report form with various informations about failure retrospectively. The present study showed 26 failed dental implants of 17 patients were removed. 13 implants(50%) of 8 patients(47.06%) were failed before functional loading and 13 implants(50%) of 9 patients(52.94%) were failed after functional loading. 11 implants(42.31%) of 7 patients(41.18%) with medical disease were extracted. 6 implants(23.08%) of 5 patients(29.41%) with additive bone graft were failed. We discuss with 26 failed dental implants of 17 patients about their causes, solutions and prevention retrospectively for 6 past years. Precise diagnosis and treatment planning are needed. Medically compromised patients and patients with implants and additive bone grafts should be cautiously treated with high failing possibilities.
