A Two-year Retrospective Study on the Clinical Success of the Korean Implant Systems

  • 1Department of Periodontology, College of Dentistry, Kangnung National University, Korea.


The purpose of this study was to evaluate the success rate of Korean implant systems. A total of 245 implants were placed in 112 patients using different implant systems from February 1988 until June 2002. Data on implant systems, implant positions, surface treatments, guided bone regeneration procedure, marginal bone levels, and states of surrounding gingiva were collected. A follow-up evaluations were done after 1 year and 2 year of loading. Clinical parameters such as probing depth was evaluated at the last follow-up. The marginal bone loss after 1 year of loading was measured on periapical radiographs. Clinical comparisons were performed to evaluate implants loss in relation to the implant systems, implant positions, surface treatments, and guided bone regeneration procedure. There was no clinical difference of success rate in implant systems, implant positions, and surface treatments. Mean marginal bone resorption from the time of loading to 1 year follow-up was 0.31mm in Korean implant systems and 0.41mm in other implant systems. The cumulative survival rate of Korean implant systems and other implant systems at the 2-year of loading was 95.6% and 97.3% respectively. From these results, it was concluded that Korean implant systems could be successfully used in clinical dentistry.
