Background : Mini implant stability is primarily related to local bone density; no studies have evaluated bone density related to mini implant placement for orthodontic anchorage between different age groups in the maxilla and the mandible.
The present research aims to evaluate side, gender, age, and regional differences in bone density of the alveolar bone at various orthodontic implant sites. Materials and method : Fifty three individuals who were divided into two groups according to their age into : group I (ages 16-20 years) and group II (ages 21-29 years) had subjected to clinical examination, then 64-multislice computed tomography scan data were evaluated and bone density was measured in Hounsfield unit at 102 points (51 in the maxilla and 51 in the mandible), and mean alveolar bone density was calculated at each site in the CT axial plane. Results : No significant differences in bone density between the sides and gender were found.
Generally, the bone density measurements of group I and II were not statistically different at almost most sites.
The mean bone density of the alveolar cortical bone was greater in the mandible than in the maxilla and showed a progressive increase from the anterior to the posterior area, while in the maxilla the highest bone density was at the premolars region.
The maxillary tuberosity was the region with lowest bone density.
Cancellous bone had almost comparable densities between the mandible and the maxilla and its density was less than those of cortical sites. Conclusion : When mini implants are indicated, no gender and side differences affect the success rate regarding bone density ; while age and area should be considered when selecting and placing mini implants for orthodontic anchorage.
