“… 4 However, Oksayan et al 5 and Yassaei et al 6 have shown that maxillary sinus dimensions are reduced in hyper-divergent individuals and vice versa. Goymen et al 7 and Bassil-Nassif et al 8 found no difference in the sinus dimensions among individuals with various mandibular growth patterns. The literature available regarding the relationship of the size of the maxillary sinus and sagittal malocclusion is conflicting.…”

This systematic review was intended to evaluate the maxillary sinus dimensions in vertical and sagittal craniofacial patterns and to assess if there was a difference among the craniofacial patterns. A systematic search was performed in seven databases till February 2021. The risk of bias was performed with modified Newcastle Ottawa scale. Meta-analysis was performed using random effects model. Twelve studies were included in the review and 8 in the meta-analysis. Compared to Class I malocclusion, the maxillary sinus area is greater in Class II and lesser in Class III malocclusion. On comparing normo-divergent growth pattern, the maxillary sinus area is lesser in hypo-divergent and greater in hyper-divergent individuals. Most of the studies were graded as satisfactory. The measurements are greater in hyper-divergent Class II malocclusion and in males.

“…e results of this study demonstrated no significant difference for the volumetric variables A, B, and C between BT and NC groups. A logical explanation could be based on the conclusions from Bassil-Nassif et al [9] advocating the existence of a compensatory mechanism among different facial dimension. ereby, a deficiency of the transverse dimension could be equilibrated by an excess in the vertical and/or the sagittal dimension which leads to maintaining constant the total nasomaxillary volume studied.…”

“…Due to the fact that, the BT group presented linear vertical values higher than those of the NC group, we can join the same rationale of the possibility of compensation of the transverse dimension by an excess of the vertical dimension, which explains further the volumetric concordance between both groups. [9] Cortella et al [2] questioned the theory that transverse dimension growth is the first to be terminated by the fact that maxillary and mandibular width increase varies as sagittal and vertical growth according to gender and chronological age. e greater mandibular than the maxillary transverse growth suggests the existence of a dentoalveolar compensatory mechanism, which permits the preservation of a normal transverse posterior occlusion.…”

“…Bassil-Nassif et al [9,10] studied different facial volumes in an adult population according to the vertical facial growth pattern and identified sexual dimorphism effect on various volumetric measurements. ey advocate the existence of a compensatory mechanism among the three facial dimensions to equilibrate an excess or deficit of the vertical dimension maintaining constant the total facial volume.…”

Objectives: The objectives of the study were to evaluate the nasomaxillary complex (NMC) measurements before and following rapid maxillary expansion (RME) compared to normal subjects. Materials and Methods: Thirty consecutive patients (14 males and 16 females) with a mean age of 9.5 ± 1.8 years for males and of 11.8 ± 1.7 years for females, who underwent RME to correct their posterior unilateral or bilateral crossbite, were selected. Computed tomography (CT) scans done before treatment (BT) formed the Group BT and those after treatment constituted the Group AT. An untreated normal sample (Group NC) presenting a normal transverse occlusion and needing a cone beam CT for other purposes was formed by 30 subjects (14 males and 16 females) with a mean age of 10 ± 0.9 years for males and of 11.6 ± 1.0 years for females. The CT scans were compared between both groups BT and AT with Group NC and measurements were performed on scanned images. The mean differences between measurements were compared using the t-test (α = 0.05). Results: No significant differences in volumetric measurements representing the NMC were found between groups BT and NC. By comparing Group AT to NC, we found that all volumetric variables displayed statistically significant differences with an increase of those of Group AT. Linear transverse variables were increased in Group NC compared to Group BT and their differences were statistically significant. However, the same variables were larger in Group AT compared to Group NC. Conclusion: RME produces an increase of the NMC dimensions compared to normal controls, which supports the principle of overcorrection, needed to compensate the post-treatment relapse.

“…Vertical facial type and orthodontic treatment are interrelated, and the alveolar bone, muscle, and malocclusion differ considerably according to the vertical facial type, which can influence therapeutic planning. 1 Vertical facial type is an indicator of craniofacial growth 2 and thus influences the selected treatment and force applied during orthodontic treatment.…”

ObjectiveTo compare the positions of the mandibular premolars in Angle Class I subjects according to vertical facial type. The results will provide a theoretical basis for predicting effective tooth movement in orthodontic treatment.MethodsCephalometric parameters were determined using cone-beam computed tomography in 120 Angle Class I subjects. Subjects were categorized as short, normal, and long face types according to the Frankfort mandibular angle. Parameters indicating the position of the mandibular right premolars and the mandible were also measured.ResultsThe angle between the mandibular first premolar axis and buccal cortex, the distance between the root apex and buccal cortex, angle of vestibularization, arc of vestibularization, and root apex maximum movable distance were significantly greater in the short face type than in the long and norm face types. The angle between the mandibular second premolar axis and buccal cortex, the distance from root apex to buccal cortex, and the arc of vestibularization were significantly greater in the short face type than in the normal face type.ConclusionsThere are significant differences in the mandibular premolar positions in Class I subjects according to vertical facial type.
