ABSTRACTIntroduction. The anchorage is one of the key elements for planning and achieving the goals of the orthodontic treatment. Their use requires the knowledge of cortical bone thickness and interradicular distances for their placement. The anatomy between male and female is different, these variations can result in changes between the mesiodistal distance between the roots, width of the buccolingual alveolar process, and buccal cortical bone thickness. Objective. To evaluate the maxillary cortical bone thickness, interradicular distances and width of the buccolingual alveolar process in men and women, using CBCT images. Method. Pre treatment CBCT images of 100 orthodontic patients were evaluated. The mesiodistal distance between the roots, width of the buccolingual alveolar process, and buccal cortical bone thickness were meassured at 3 levels. Descriptive statistical analysis and t-tests were performed, with significance level for all tests set at p ‹ 0.05. Results. It was found statistical difference in the mesiodistal distance between the roots, width of the buccolingual alveolar process, and buccal cortical bone thickness between men and women. Conclusion. It is important to consider the sex of the patients in the selection of the mini screw and the insertion zone, because of the differences found in the study.
