Many implant systems have been introduced because of the widespread use of dental implant treatment. This study com pares the incidence and etiology of early implant failures with domestic and imported implant systems. The medical records at the Seoul National University Bundang Hospital from June 2003 through December 2007 were reviewed to identify gen der, age, implant location, systemic disease, post-operative complication and marginal bone resorption. A total of 888 implants in 296 patients were included. The median duration of follow-up was 28°æ10 months. The incidences of early implant failure were 1.9%(Domestic-1), 1.9%(Domestic-2), 2.2%(Domestic-3), 1.8%(Domestic-4), 0.0%(Domestic-5), 3.2%(Imported-1), 19.2%(Imported-2), 0.0%(Imported-3), 16.7%(Imported-4). There were significant differences among domestic and imported implant systems in early failure. There were significant differences in post-operative marginal bone loss among implant systems at 1-year follow-up. The range of early implant failure was between 0.0% and 19.2%. These data indicate that domestic implant systems deliver excellent clinical results compared with imported implants. Further studies will be required to consider other multiple factors associated with early implant failure and marginal bone loss.
