It is therefore considered that MDCT is appropriate for the precise evaluation of bone density. However, since the use of CBCT is spreading rapidly among general practitioners, it is clinically of great significance to predict the primary stability after implant placement using the information obtained by CBCT. In addition, in late years, CBCT or the calibration software which can convert the voxel values into CT values is developed.
We therefore investigated in this study the correlation between the thickness of the cortical bone or the voxel values that are obtained by CBCT and the ITVs or the ISQ values.
