Objective:The 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 GS),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.
