Purpose: To evaluate RBM surface implant which has its good character like that good initial stability, early bone formation. Material and Methods: In this study fixures have divided in 2 group: Machined(Group Ⅰ), RBM(Group Ⅱ). Total 10 fixtures were implanted on rabbit which sacrificed on week 2 and week 4 for the histological specimens. By these specimens polarized microscopic view, micro CT view, ISQ value were measured, compared and analysed by each group to figure out the evidence that clinical use of RBM implant. Result: ISQ value had no significance differences between 2 groups, However in each group 4, 8 weeks had higher ISQ value than 2 weeks. In polarized microscope, calcification level was following : Group Ⅱ, Group Ⅰ. In micro CT, formation of cancellous bone level was following : Group Ⅱ, Group Ⅰ. Conclusion: RBM implant was the most excellent on the early bone formation and good initial stability. (J Korean Acad Periodontol 2008;38:467-474)
