![]() ![]() ![]() For all eligible patients, CBCT images were obtained as part of their initial records. This descriptive, retrospective study included digital lateral cephalograms (DLCs) and CBCT records of 88 patients recruited from different private practices in the cities of Cartagena (n = 10), MedellĂn (n = 39), and Pereira (n = 39) in the country of Colombia. Accordingly, we explored the optimal site for miniscrew insertion in this area. Therefore, the purpose of this study was to evaluate MBS in terms of the angulation and bone depth and thickness according to sex, age, sagittal skeletal pattern (SSP), and vertical skeletal pattern (VSP) using cone-beam computed tomography (CBCT) images in a Colombian population. 13 However, variations in the depth and thickness of the bone along its course may affect miniscrew placement. 12, 13 MBS is bilaterally located buccal to the roots of the first and second mandibular molars and anterior to the oblique line of the mandibular ramus, and it provides adequate quantity and quality of bone for miniscrew insertion. 1, 9 - 11 In cases requiring retraction of the lower teeth, MBS is the best area for miniscrew insertion in the extra-alveolar bone of the posterior zone of the mandible. 7, 8 The most preferred sites for their placement are the interradicular vestibular alveolar zone, hard palate, and infrazygomatic crest and in the mandible, these regions include mandibular triangle, retromolar area, and mandibular buccal shelf (MBS). ![]() Some researchers have evaluated bone characteristics in different regions of the maxilla, mandible, and alveolar bone in order to identify the best places for miniscrew insertion. ![]()
