Objectives: We aimed to determine safe areas to apply miniscrews in the interradicular region of the maxilla and mandible in individuals with various sagittal skeletal malocclusions.

Materials and Methods: Cone beam-computed tomography images of 159 individuals were used. Individuals were divided into three groups: Class I, Class II and Class III. In the sagittal plane, 3–6–9-mm apical sections were determined from the alveolar crest apex. The buccal cortical bone thickness, interradicular distance and buccolingual bone distances were measured.

Results: In the buccal cortical bone thickness, we observed statistically significant differences between the classes except for the 1-1 region in the maxilla and all regions and sections in the mandible (p<0.05). The differences in the buccolingual bone distance between classes were statistically significant, except for the 3-mm and 6-mm sections in the 3-4 and 4-5 regions of the maxilla, the 9-mm sections in the 1-2 and 2-3 regions, the 6-mm and 9-mm sections in the 3-4 region and the 6-mm section in the 4-5 regions of the mandible (p<0.05). The differences in the interradicular bone distance were statistically significant between the classes in all regions and sections of the mandible except the 6-mm sections in the 1-2 region and in all sections of the maxilla except the 6-mm sections in the 3-4 region (p<0.05).

Conclusions: We observed significant differences in the buccal cortical bone thickness, interradicular bone distance and buccolingual bone distance among individuals.

Clinical Relevance: Understanding the anatomy of interradicular regions and preventing complications.
