- 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 3mm posterior to the incisive foramen and 1 to 5 mm to the paramedian side.
