Before correction
Materials and Methods: A total of 105 patients who had 467 Osstem implants that were placed at the Section of Dentistry, Seoul National University Bundang Hospital (Seongnam, Korea) from June 2003 through December 2005 were analyzed. The life table method and a cross-tubulation analysis, log rank test were used to evaluate the survival curve and the influence that the prognostic factors. The prognostic factors, i.e., age and gender of patients, diameter and length, type of implants, bone graft history and loading time were determined with a Cox proportional hazard model based on logistic regression analysis.

The life table method and a cross-tabulation analysis were performed to evaluate the cumulative survival rate. The log rank test was used to evaluate the survival curve. The influence that the prognostic factors had on the survival rate was determined with a Cox proportional hazard model based on logistic regression analysis.
