Issue Date: | 2014 | Publisher: | NATURE PUBLISHING GROUP | Source: | BONE RESEARCH, 2 | Abstract: | Cone-beam computed tomography (CBCT) has been recently used to analyse trabecular bone structure around dental implants. To validate the use of CBCT for three-dimensional (3D) peri-implant trabecular bone morphometry by comparing it to two-dimensional (2D) histology, 36 alveolar bone samples (with implants n=27 vs. without implants n=9) from six mongrel dogs, were scanned ex vivo using a high-resolution (80 mu m) CBCT. After scanning, all samples were decalcified and then sectioned into thin histological sections (similar to 6 mu m) to obtain high contrast 2D images. By using CT An imaging software, bone morphometric parameters including trabecular number (Tb.N), thickness (Tb.Th), separation (Tb.Sp) and bone volume fraction (BV/TV) were examined on both CBCT and corresponding histological images. Higher Tb. Th and Tb. Sp, lower BV/TV and Tb.N were found on CBCT images (P<0.001). Both measurements on the peri-implant trabecular bone structure showed moderate to high correlation (r=0.65-0.85). The Bland-Altman plots showed strongest agreement for Tb.Th followed by Tb.Sp, Tb.N and BV/TV, regardless of the presence of implants. The current findings support the assumption that peri-implant trabecular bone structures based on high-resolution CBCT measurements are representative for the underlying histological bone characteristics, indicating a potential clinical diagnostic use of CBCT-based peri-implant bone morphometric characterisation. | Notes: | [Huang, Yan; Van Dessel, Jeroen; EzEldeen, Mostafa; Jacobs, Reinhilde] Univ Leuven, Fac Med, Dept Imaging & Pathol, OMFS IMPATH Res Grp, Leuven, Belgium.
