三种种植系统周边骨质吸收的对比研究
A comparative study to the marginal bone loss of three implant systems.
摘要
Abstract
Objective: Hie purpose of this study is to evaluate the difference of marginal bone loss around the implant with butt-joint or platform-switched implant system on the panoramic radiograph. Method: 54 butt-joint implants (Noble Replace) . 14 small platform-switched implants (Osstem CS). 25 oblique style platform switched implants (Bicon) were consecutively placed. Panoramic radiograph was taken at immediately after implant placement and 3 months after functional loading. Marginal bone level and marginal bone loss were measured on the panoramic radiograph. All data was statistical analysis by SPSS14.0 software. Result: 3 months after functional loading, the mean bone absorptive amount on the mesial and distal of the bult-joint implants were 1.88 mm±1.49 mm and 1.81 mm±1.34 mm;obligue style platform switched implants were -0.68 mm±0.99 mm and -1.17 mm±1.37 mm; small platform swifched implants were 0.53 mm±1.48 mm and 0.74 mm±0.99 mm. Three implant systems were comparison of pair wise* their difference were shown to be significant (P < 0.05). Conclusion: Platform switching technology can reduce the marginal bone absorptive amount around dental implant; moreover) different platform switching designs have strikingly different ability in saving the bone around the implant.关键词
