Abstract
Objectives: To compare maxillary and mandibular cortical bone thickness and root proximity for optimal mini-implant placement.
Materials and methods: CBCT images from 21 men and 26 women were used to evaluate buccal inter-radicular cortical bone thickness and root proximity from mesial of the lateral incisor to the 2nd molar in the maxilla and mandible. Cortical bone thickness, buccolingual thickness and inter-radicular distances were measured at 2, 5, 8 and 11 mm height from the alveolar crest using three-dimensional images.
Results: For the cortical bone thickness, there was no statistically significant difference between the maxilla and the mandible in the anterior area; however, there was a significant difference in the posterior area. Cortical bone in the maxilla, mesial and distal to canine inter-radicular sites, was thickest while thickness in the mandible exhibited a gradual anterior to posterior increase. Root proximity mesial and distal to 2nd premolar inter-radicular sites was greatest in maxilla, and for mandible it was greatest in mesial and distal to first molar.
Conclusion: Based on our results, cortical bone thickness depends on the inter-radicular site. It is greater in mandible as compared to maxilla and the difference is statistically significant for posterior regions. Buccolingual measurements are greater in maxilla than mandible and the difference is not statistically significant. Mesiodistal distances are greater in mandible than maxilla and the difference is statistically significant for posterior regions.
