Abstract
Objectives: To evaluate palatal bone density to allow for better selection of palatal implant anchorage sites. Materials and Methods: Computed tomographic (CT) images were obtained from 15 males and 15 females (mean age, 27 years; range, 23-35 years). Bone density was measured in Hounsfield units (HU) at 80 coordinates at regular mediolateral and anteroposterior intervals along the midpalatal suture. Results: Bone densities ranged from 805 to 1247 HU. A significant difference between male and female groups was noted, although no difference was found between left and right sides of individual palates. Palatal bone densities showed a tendency to decrease laterally and posteriorly. The midpalatal area within 3 mm of the midsagittal suture had the densest bone in the entire palate. Conclusion: Results suggest that mini-implants for orthodontic anchorage may be effectively placed in most areas with bone density equivalent to the palatal area if they are placed from 3 mm posterior to the incisive foramen and 1 to 5 mm to the paramedian side. © 2010 by The EH Angle Education and Research Foundation, Inc.
