Abstract
Purpose: To evaluate bone formation on the implant surface between machined fixture and RBM surface fixture through analyzing of distribution and concentration of Ca and P by EPMA.
Material and Methods: Fixtures had divided in 2 group: Machined(Group Ⅰ), RBM (Group Ⅱ). Total 4 fixtures were implanted on rabbit which sacrificed on 2 week and 4 week for the histological specimens. By these specimens EPMA value were measured, compared and analysed by each group to figure out the evidence of clinical use of RBM implant.
Result: After 2 weeks and 4 weeks , it was analyzed that bone formation area, distribution and concentration of Ca and P by EPMA. In distribution and concentration of P Group Ⅱ was higher than Group I, but there were no statistical
significances. In new bone formation area, Group Ⅱ was more higher than Group Ⅰ with statistically significances. Both of group, after 4 weeks area is little bit higher than after 2 weeks area but there is no statistically significances.
Conclusion: RBM implant was better than machined implant on the early bone formation.
