Introduction. In this study, we applied the immediate loading to implant using temporary prosthesis, and compared the treatment results by each placement site, amongst pre-loading period. The study was intended to search for occurrence of complications and the amount of marginal bone resorption. Materials and Methods. We retrospectively reviewed the medical records of 99 cases of implants from 29 patients who were treated at Seoul National University Bundang Hospital from September 2003 to September 2008. We grouped all the cases by placement arches and pre-loading periods, and subdivided each group by placement site(anterior/posterior), type of prosthesis(full-mouth cross splinting/Partial multiple splinting, Single). Results. In the cases of anterior maxilla, the average amounts of marginal bone resorption showed $1.71{\pm}0.71mm$ in group 1, and $1.44{\pm}0.69mm$ in group 2, which means they revealed no statistically significant difference between group 1 and group 2(p=0.646). In the cases of posterior maxilla, the average amounts of marginal bone resorption showed $1.25{\pm}0.72mm$ in group 1, and $1.14{\pm}1.15mm$ in group 2, which means they were not statistically significant. In the cases of anterior mandible, there was no cases classified as group 4, but the average amounts of marginal bone resorption in group 3 showed $1.38{\pm}0.79mm$. In the cases of posterior mandible, Group 3 showed $1.39{\pm}0.64mm$, and group 4 showed $1.84{\pm}1.19mm$ as amounts of marginal bone resorption, which means they revealed no statistically significant difference between group 3 and group 4(P=0.210). The survival rate of group1 was 97.14%, 92.1% of group3, and 100% of group 2 and group4. According to each type of prosthesis, each average amount of marginal bone resorption revealed no statistically significant difference in maxi11a(p=0.575) in mandible(p=0.206). Conclusion. It is concluded that the marginal bone resorption and the rate of complications might not be affected by placement sites and pre-loading periods. The marginal bone resorption and the rate of complications might vary as different bone quality of placement site and implant system, diameter, length, etc. It is suggested that the proper placement of immediate loading implants decreases the whole treatment period and any inconvenience occurred to patients.
