Abstract
To evaluate the clinical effectiveness of the straight (Osstem GS II) and tapered body (Osstem GS III) implant system. The survival rate and marginal bone loss of 101 implants placed in 36 patients were evaluated retrospectively. In Department of Oral and Maxillofacial Surgery, Seoul National University Bundang Hospital analyzed the medical records of patients who had completed the implant placement between 2005 and 2010. Sex, implant location, diameter and length were investigated. Also, implant survival rate, marginal bone loss, complications were analyzed. The amount of marginal bone loss was measured at 1 year after prosthetics placement and at the last follow up, by panorama and periapical radiography. An independent t-test was used for the analysis of the association of marginal bone loss of GS II and GS III (p=0.05). Out of the 101 implants, which were done on 36 people, 8 implants failed and survival rate was 92.1%. Marginal bone loss at 1 year after prosthetics placement was 0.23 mm in GS II, and 0.05 mm in GS III. At the last follow up, marginal bone loss was 0.51 mm in GS II and 0.29 mm in GS III. Statistically analyzing the long-term marginal bone loss difference between GS II and GS III implant system, the p-value was 0.756 and there was no statistically significant difference between the two. Long-term clinical outcomes of domestic implants by implant systems Osstem GS II and GS III have been satisfactory, and no significant difference in marginal bone loss was observed.
