Materials and Methods: In this study, GS-II implant (Osstem Co., Korea) was used. GSII implant fixture is a dualthreaded internal connection type with upper microthreads and CellNest surfaces (anodic oxidation treatment). Three early loaded implants groups (5 days, 20 days, 50 days after surgical treatments) and an unloaded implant control group in the edentulous maxilla were retrieved with a 5.0 mm trephine bur. Histomorphometric analysis - percentage of bone-to-implant surface contact (BIC) and bone volume - was perfomed through digital imaging analysis. Results: The histologic data showed that the osseointegration was achieved in both loaded and unloaded conditions. Five days group showed slightly higher BIC and bone volume than other early loaded groups. Unloaded group was failed to compare. Conclusion: Within the limitations of the study, the clinical and radiological results showed that the osseointegration was achieved. Immediate functional loading of implants could lead to favorable bone responses. More studies are needed so that proper and faster way of loading implants can be developed.
