ترجمة الملخص

The transverse dimension of the face and jaws is considered as one of the essential dimensions that must be studied to accomplish a balanced functional occlusion. Its importance arises in skeletal Class II subjects owing to the wide prevalence of this type of skeletal relationships in the Caucasian population especially in Syrians .The problem in arch width might be related to the arch itself and interactions between the arches or may result from factors outside the arch. The transverse dimensions of the zygomatic arch could be one of the valuable facial dimensions that might correlate with the dentoalveolar structures due to the anatomical importance of the zygomatic arch in its relations with the masticatory system muscles and attachment to the maxillae.Aims:The aim of this research is the study of potential presence of a relationship between the bizygomatic distance and the interalveolar widths in the upper and lower arches. Also, to investigate the gender effect in such a relation and in the studied transverse dimensions themselves, in untreated adults,using Cone-Beam Computed Tomography (CBCT). Materials and methods:The research sample consisted of 42 adults with skeletal Class II relationships with no prior orthodontics treatment. The interalveolar width measurements (buccal and palatal/lingual) were performed in upper and lower arches at the level of first premolar and first molar in each arch . Person correlation test was applied to investigate the relationship between the interalveolar widths and the bizygomatic distance that was measured using the coronal slices of CBCT images, in both genders. Independent-Samples T test was applied to study differences between males and females in each transverse dimension itself whether zygomatic or alveolar. Results:The results of the research showed the presence of proportional correlation between the bizygomatic distance and the interalveolar width in skeletal Class II subjects. This correlation was higher with the interalveolar width in the upper arch than in the lower , especially at the level of the first molar, and higher in males than in females. As to gender differences in transverse dimensions ; the bizygomatic distance and also the interalveolar width at the level of upper first molar were statistically wider in males than females.Conclusions:The bizygomatic distance is one of the important facial dimensions that affects the measurement of the alveolar arches transverse dimension in adults with skeletal Class II relationships. Males have wider facial and alveolar dimensions than females
