Abstract Objectives The first purpose of this study was to analyze the correlation between bone volume fraction ( BV / TV ) and calibrated radiographic density Hounsfield units HU in human jaws, derived from micro‐ CT multislice computed tomography MSCT ), respectively. second aim assess accuracy cone beam CBCT evaluating trabecular microstructure using , respectively, as reference gold standards. Material methods Twenty partially edentulous mandibular cadavers were scanned by three types modalities: (Philips, Best, Netherlands), (3D Accuitomo 170, J Morita, Kyoto, Japan), (SkyScan 1173, Kontich, Belgium). Image analysis performed Amira (v4.1, Visage Imaging Inc., Carlsbad, CA USA), 3Diagnosis (v5.3.1, 3diemme, Cantu, Italy), Geomagic (studio ® 2012, Morrisville, NC CTA n (v1.11, SkyScan). scans each mandible matched select exact region interest ROI ). gray value derived. Statistical correlations corresponding measurement parameters. Results Strong observed r = 0.89) measurements 0.82). Excellent 0.91). However, significant differences found all comparisons pairs P < 0.001) except for mean 0.147). Conclusions An excellent exists assessed on This suggests that could be used estimate microstructural A strong also values their standards, suggesting potential modality quality assessment at implant site.
