Background: This study aims to evaluate the volume and density of the anterior maxillary region in Class II and Class III patients using cone-beam computed tomography (CBCT) and to investigate whether there are differences between these two patient groups that could affect the stabilization of plates and screws. Methods: CBCT images of 48 patients (24 Class II and 24 Class III) were retrospectively examined. The volume of the maxillary anterior region (between the midline and the canine teeth), surface area and average density were calculated from the tomography images. Additionally, the distances of the maxillary canine, lateral and central teeth to the nasal fossa were measured. Results: No statistically significant differences were found between skeletal Class II and III patients in maxillary volume, surface area, density, or the vertical height of maxillary teeth to the nasal fossa floor (p>0.05). A statistically significant difference was observed between volume and surface area measurements on the right and left sides according to gender (p<0.05). Conclusion: There are no morphological differences between class II and class III patients that may affect the stabilization of the plates and screws used in the anterior region in Le Fort I osteotomy. However, preoperative evaluation of the distance between the anterior tooth roots and the nasal fossa and taking these distances into account when placing the screws is important in order to prevent damage to the tooth roots and to preserve tooth vitality.
