Figures
- Fig. 1
Detection of the cylindrical dowel with original image (a), dowel probability map (b), Hough transformed image (c), and line fitting through the maxima of the Hough images (d).
- Fig. 2
Images sampled at 30 voxels from the implant surface and stratified for visualization.
- Fig. 3
Volumes of interest (blue) around the dowel (orange). In this figure, 24 VOIs are drawn (3 times 8). In our analysis we use 60 VOIs (5 times 12).

Representative slices for titanium, (A), CaP, (B) and control (C).

Time * Treatment statistics for BIC in the 6 to 26 weeks period. No significant differences were observed (p = 0.24100).
- Fig. 6
Time * Treatment statistics for BIC in the 6 to 12 weeks period. BIC was significantly higher in the titanim group compared to the control.

Time * Treatment statistics for BV/TV in the 6 to 26 weeks period. No significant differences were observed (p = 0.28789).
- Fig. 8
Time * Treatment statistics for BIC in the 6 to 12 weeks period. BIC was significantly higher in the titanium group compared to the control.
- Fig. 9
Correlation between BIC and BV/TV.

Histological sections stained with Stevenel's blue and Von Gieson's picrofuchsin of (a) titanium with direct bone implant contact, (b) CaP with direct bone implant contact (c) Control presence of cartilage tissue and fibrotic layers between the dowel and the surrounding bone tissue.
