| Abstract | Introduction: The purpose of this study was to determine the most coronally located interradicular sites for miniscrew placement, and to compare gender, ethnic and insertion site groups. Methods: CBCT images from 60 patients were rendered using InVivo DentalTM Software. A vertical measurement was recorded from the most coronal presence of 3 mm of interradicular space to a horizontal line connecting the CEJs of adjacent teeth at 18 sites. Results: No significant differences were found between the right and left sides of the mouth. Statistically significant differences (p < .0001) existed between sites, and upper vs. lower sites. Statistically significant differences between gender and ethnic groups existed between lower left bicuspids and lower right molars. Conclusion: Sufficient bone for placement of miniscrews through attached gingiva existed primarily between mandibular molars. Sites mesial to mandibular and maxillary molars had bone stock located further apically, which would make miniscrew placement through attached gingiva unlikely. |
