“…We could not find the significant effects of the premolar extraction, posterior teeth distalization, and type of multibracket appliance on the maxillary sinus dimensions. Ciğerim et al [ 7 ] evaluated the influence of maxillary molar distalization on maxillary sinus volume and suggested that patients treated with molar distalization showed a significant increase in the maxillary sinus volume compared to patients without molar distalization. Portes et al [ 16 ] evaluated the volumetric change of the maxillary sinus in patients who underwent miniscrew-anchored maxillary posterior tooth intrusion and suggested that miniscrew-anchored maxillary posterior en masse intrusion did not significantly affect the maxillary sinus volume.…”

“…The maxillary sinus is a multifunctional bony cavity that forms at a late stage in fetal life. It measures approximately 144 mm 3 at birth and grows pyramidally into adulthood [ 7 ]. The sinus floor enlarges to the posterior alveolar process, pneumatizes the alveolar cavity, and, in some cases, causes the penetration of molar root apices into the sinus [ 7 ].…”

The sinus floor enlarges to the posterior alveolar process, pneumatizes the alveolar cavity, and, in some cases, causes the penetration of molar root apices into the sinus [ 7 ]. It contributes to facial growth, reduction of skull weight, and absorption of traumatic impacts on cranial skull structures [ 8 ].…”

“…New bone formation on the sinus floor can be stimulated by orthodontic tooth movement [ 13 , 14 ]. Given this information, tooth movement passing through the maxillary sinus has an effect on the sinus dimensions and volume in comparison to the sinus without tooth movement [ 7 , 15 ]. However, predicting the volumetric and dimensional changes in the maxillary sinus after orthodontic treatment is still unclear.…”

“…Recently, several studies have suggested that biomechanical stimulation has dimensional and volumetric effects on maxillary sinus in adults [ 7 , 10 ], while other studies have reported less or minimal effects on maxillary sinus dimensions and volume [ 16 , 17 ]. However, the hypothesis remains controversial.…”

Objective This study aimed to investigate the correlation of craniofacial morphology with maxillary sinus morphology and to evaluate whether orthodontic treatment facilitates maxillary sinus enlargement in adults. Materials and methods A total of 45 adult women underwent cephalography and computed tomography before and after orthodontic treatment. All participants were classified into three groups: skeletal class I, II, and III. The average dimensions and volume of the maxillary sinus were calculated in each subgroup. Furthermore, multiple regression analysis was used to analyze the correlations of maxillary sinus dimensions with 20 cephalometric variables. Results Before treatment, the maxillary sinus width, height, depth, and volume were 32.2 ± 3.9 mm, 39.5 ± 3.8 mm, 38.6 ± 1.8 mm, and 36,179.3 ± 5,454.0 mm 3 in skeletal class I, 33.9 ± 6.2 mm, 37.3 ± 3.5 mm, 38.6 ± 2.4 mm, and 34,729.8 ± 6,686.6 mm 3 in skeletal class II, and 32.0 ± 4.3 mm, 41.8 ± 5.0 mm, 38.0 ± 2.8 mm, and 35,592.3 ± 10,334.3 mm 3 in skeletal class III, respectively. Despite no significant differences in maxillary sinus width, depth, or volume, the height was significantly lower in the skeletal class II than in the other two. Regardless of the skeletal pattern, maxillary sinus height and volume increased considerably after treatment. Moreover, the maxillary sinus width was substantially involved in pretreatment U1 to SN and overbite and posttreatment U1 to NA and overjet. Conclusion Except for the height, the maxillary sinus dimensions were almost similar, irrespective of the skeletal classification. The posttreatment sinus height and volume were significantly greater than the pretreatment values, although the sinus width and length showed no significant changes during orthodontic treatment. This implies that orthodontic treatment may facilitate the enlargement of the maxillary sinus even after physical growth.
