Abstract:
Objective:To investigate the feasibility of cone-beam CT (CBCT) in evaluating the thickness of cortical bone in jaw bone.Methods:Sixty patients [twenty-three for males and forty-seven for females, at an average age of (43.8±1.7) years] from Center of Stomatology, The First Affiliated Hospital of USTC & Anhui Provincial Hospital with 63 operational regions were included in the present study. Totally 63 bone sections from these areas were all selected at last. Case Viewer and oral dynamic system were used for the measurements in sections and CBCT graphs of the cortical bone thicknesses at alveolar ridges. Paired samples t test was performed to compare the difference between CBCT measurement and Case Viewer measurement. Results:The cortical bone thicknesses measured by Case Viewer were (1.20±0.75), (0.68±0.46) and (1.48±0.77) mm in the posterior, maxillary posterior and mandibular posterior areas, respectively. The cortical bone thicknesses measured by dynamic navigation software were (1.14±0.77), (0.64±0.24) and (1.41±0.83) mm in the posterior, maxillary posterior and mandibular posterior areas, respectively. There were no significant differences between either the two methods or the different areas ( P>0.05). Conclusions:CBCT would be a useful equipment for the analysis of cortical bone thickness with a reliable and convincible accuracy.
