Cross-sections were obtained and cortical and cancellous bone densities on different aspects of the virtual implant in terms of Hounsfield unit (HU) were determined using New Net Technologies software version 6.1 and were classified according to software from D1 to D4.

Maximum D1 bone type was found in cortical bone and D2 bone type was noted in cancellous bone area.
