“…A deeper knowledge of its three-dimensional changes could be useful even in orthodontics [2]. In fact, orthodontic treatments involving sliding mechanics of posterior maxillary teeth, especially if one or more of them are missing, should be performed after an accurate evaluation of the relationships between the apexes of the aforementioned teeth and the cortical floor of the maxillary sinuses that could represent an obstacle to their correct movement [38,39]. Tooth movement in cortical bone is indeed considered an anatomical limitation in orthodontics because of its slower turnover and higher density [40][41][42].…”

This study aims to evaluate changes of maxillary sinuses in growing subjects. Cone Beam Computed Tomography (CBCT) scans of 146 patients were divided according to gender and age (6–8, 9–11, 12–14 years old). Left, right and total maxillary sinus volume (MSV-R, MSV-L, MSV-Tot) and surface (MSS-R, MSS-L, MSS-Tot), left and right linear maximum width (LMW-L, LMW-R), depth (LMD-R, LMD-L) and height (LMH-R, LMH-R) were calculated using Mimics Research 22. Kruskal–Wallis Test and showed a statistically significant increase in both genders for all variables. Pairwise comparisons in females are always statistically significant in: LMH-R, LMH-R, MSS-Tot, MSV-Tot. All other variables showed a statistical significant increase between 9–11 and 12–14, and between 6–8 and 12–14 age groups, apart from LMSW-R, LMSW-L, LMSD-R, LMSD-L between 6–8 and 12–14 age groups. Pairwise comparisons in males are always and only statistically significant between 9–11 and 12–14, and between 6–8 and 12–14 groups. Symmetrical measurements (right and left) evaluated using Wilcoxon test retrieved no statistical significant difference. Comparisons between measurements on male and female subjects using Mann–Whitney test showed a statistical significant difference in 6–8 years group in MSV-R, MSV-L and MSV-Tot, and in 12–14 age group in MSV-R, MSV-L, MSV-Tot, MSS-r, MSS-l, MSS-Tot, MSW-R, MSW-L, MSD-R, MSD-L. Intraclass Correlation Coefficient (ICC) assessing inter-operator and intra-operator concordance retrieved excellent results for all variables. It appears that maxillary sinus growth resembles the differential peak of growth in male and female subjects. Sinuses starts to develop early in female subjects. However, in the first and last age group female sinuses are statistically significantly smaller compared to male ones. In male subjects, sinus growth occurs mainly between the second and third age group whilst in female subjects it starts between the first and second age group and continues between the second and the last. Sinus has a vertical development during the peak of growth, which is the main reason for its increase in volume.

Background: The correlation between extension of the maxillary sinus floor and vertical facial skeletal patterns is important for designing orthodontic treatment plans. We correlated the extension of the maxillary sinus (MS) floor with different facial skeletal malocclusion in adolescent patients aged 10-19 years old using a cone-beam computed tomography. Methods: The relationship between the root tips of upper posterior teeth and the sinus floor was typed and scored (0-4) using cone-beam computed tomography (CBCT) images. Scores of each tooth and each patient were formulated.The cephalometric radiographs were analyzed with Dolphin software to diagnose patients' facial skeletal types into three groups according to Frankfort mandibular plane angle (FMA) as high-angle, average-angle and low-angle groups and ANB angle as Class I, Class II and Class III groups separately. The influences caused by age, sex, and facial skeletal malocclusion on the tooth and patient score were analyzed. Results: In high-angle group, the first molar (FM) score was significantly higher than that in the average-angle and low-angle groups (P = 0.018). Age has a positive effect on the patient score and some of the tooth scores, such as the second premolar (SPM) score, FM score, and the second molar (SM) score, and in the skeletal facial malocclusion. With increasing age, SM score increased along with the Frankfort mandibular plane angle (FMA). No significant difference was found in the distribution of patient and tooth scores by ANB angles. Conclusion: The relationship between the maxillary posterior roots and the sinus floor is correlated with facial skeletal malocclusion in 10- to 19-year-old adolescents. More first molar root tips were inside the sinus in the high-angle group compared with the average-angle and low-angle skeletal patterns. With advancing age, more second molar root tips were more close to contact the sinus floor in the high-angle group. Consideration of the root-sinus position in the posterior maxillary area before establishing an orthodontic treatment plan is recommended.

“…Ainsi, un développement sinusien plus vertical avec un prolongement profond favoriseront un degré plus important de version. Des rapports récents ont montré que déplacer une dent à travers le sinus maxillaire est possible, sous réserve d'un très bon contrôle du mouvement de cette dent [22,26]. Un implant peut, par la suite, être posé dans le site préalablement occupé par la dent ainsi déplacée.…”
