Figure 2: The CT images of implant. (a) 3D reconstruction of ROI (implants). The left sights reflect the positions of implants in rats, and the right sights reflect the shape of implants (the color depth roughly reflects the CT value). The CT values are in an uptrend while the volume of implants is in a downtrend. (b) The CT images at the 28th day. The outline of implants is not as clear as ultrasound image (red arrow points to the CS Group and yellow arrow to the CS/nHAC group).
