Abstract: The purposes of this study were to evaluate the bone characteristics; the alveolar process width (APW), cortical bone thickness (CBT), cortical bone density (CoBD), and cancellous bone density (CaBD) of the maxillary regions commonly used for miniscrew implant placement and to compare the bone characteristics between patients with different vertical skeletal patterns. Using Cone-beam computed tomography (CBCT) images obtained from 39 patients, age 20-30 years, the APW, CBT and bone density were measured with Dolphin Imaging software. On buccal side, the APW, CBT, CoBD, and CaBD values ranged from 7.95±1.40 to 12.25±3.95 mm, 1.14±0.27 to 1.35±0.33 mm, 1,025.7±157.09 to 1,167.5±181.50 Hounsfield units (HU), and 398.54±45.47 to 408.71±44.48 HU, respectively. On palatal side, the APW, CBT, CoBD, and CaBD values ranged from 9.08±4.39 to 10.79±5.10 mm, 1.28±0.28 to 1.37±0.29 mm, 1,001.5±148.02 to 1,048.2±128.14 HU, and 416.29±41.76 to 421.73±53.74 HU, respectively. Comparing of bone characteristics between vertical skeletal patterns there were no statistically significant difference in this study parameter, except palatal CBT and buccal CaBD in hyperdivergent group were less than other groups. In conclusion, the bone characteristics of the maxillary interradicular spaces from premolar to molar regions were appropriate for miniscrew implant placement and the results indicated that it should be cautiously taken into account when placing miniscrew implants in the patients with hyperdivergent skeletal pattern.
