Abstract
In order to study the validity of the rest implantation period for one-step dental implant,we studied the radiographic differences between dental implant with the rest implantation period of three months and that with temporary fixation just after the implantation surgery. Bioceram dental implants (Kyocera) were used in this study, and all cases of this study were performed by the same dentist. Bioceram implants with the rest implantation of three months showed no mobility after occlusal stress,and no radiolucent space around them. However, Bioceram implants with temporary fixation showed mild mobility and the radiolucent space around those implants. Results reveal that the rest implantation period is necessary to get a good prognosis for one-step dental implants.
