The relationships of the thickness of the cortical bone and the voxel values with the ITVs and the ISQ values were analyzed using Pearson's correlation coefficient. Then, multiple regression analysis was performed using the ITVs or the ISQ values as the dependent variable and using the thickness of the cortical bone, the voxel value, and the length of the implant as the independent variables to evaluate the influence on the ITVs and the ISQ values among multiple factors. The statistical analyses were performed using the SPSS ver. 22 software (SPSS Co., Chicago, IL, USA). P < 0.05 was considered statistically significant.
