The aim of this study is application of micro-CT to observe the tissue surrounding dental implants at rabbit’s bone. The rabbit’s bone with the implants were removed 6 weeks after implantation and preserved in formalin. Micro-CT analysis was performed using three types of machine, and data obtained were compared. The best conditions were taken to obtain the best images for each equipment.

Many artifacts appeared with TOSCANER-31300 mhd^®, but disappeared with TDM1000^®. SkyScan-2011^® provided the most detailed images.

Micro-CT made possible quantitative analysis of newly formed bone surrounding the dental implants.
