Abstract
Objective To compare the marginal bone resorption of two implant systems which were applied to the restoration of single tooth missings. Methods 60 patients of single odontoptosis were divided into two groups with 30 patients in each group. Patients of different groups were treated by Xive impant system and Ankylos impant system. Orthopantomographies were taken on the operation day,3 months,6months,and 12 months after implant placement. Marginal bone altitude and marginal bone loss were measured on the orthopantomographies. All data were statistically analyzed by SPSS14.0 software. Rusults There were no severe complications in the both groups,and the stability in initial stage was good. Marginal bone resorption of 4.5mm Xive impant on the operation day, 3rd month, 6th month ,and 12th month after implant placement were(0.42 ± 0.28),(0.81 ± 0.34),(1.24 ± 0.38),(1.69 ± 0.42)mm.Marginal bone resorption of 4.5 mm Ankylos impant on the operation day, 3rd month,6th month,and 12th month after implant placement were(0.32±0.23),(0.36±0.27),(0.42±0.3), (0.52 ± 0.31)mm. There were statistically significant differences in marginal bone resorption between the two implant systems(P<0.05). The mean marginal bone resorption of Xive impant(1.06mm) was higher than that of Ankylos impant(0.42mm). Conclusion Ankylos impant which is designed by platform switching could reserve the marginal bone altitude better than Xive impant which is designed by platform joint in one years function load.关键词
