الهدف تقييم ثلاثي الابعاد للتغيرات الطارئة على الطرق الهوائية العلوية و الناتجة عن المعالجة الوظيفية بجهاز القطعة التوأمية عند مرضى الصنف الثاني المترافق مع تراجع الفك السفلي باستخدام التصوير المقطعي المحوسب ذي الحزمة المخروطية.
Objective: This research aimed to evaluate the three-dimensional
effects of a Twin Block (TB) appliance on the pharyngeal airway
passage (PAP) in a sample of Class II patients with mandibular
retrusion using cone-beam computed tomography (CBCT).

The RME force is not only concentrated on widening the maxilla,
it is concomitant changes occur in craniofacial sutures, from here
the need for this study was originated.
Aim of the study: To investigate the immediate effect of rapid
maxillary expansion on the spheno-occipital Synchondrosis in
children using cone beam computed tomography.
Class II malocclusion is a common clinical problem among white Caucasian population and its transverse component is a critical aspect of a functional and stable occlusion. The size and shape of the arches have considerable implications in orthodontic
It is difficult to choose between the rapid maxillary expansion
(RME) and surgically assisted RME (SARME), we aimed to study the
relationship between the obliteration index in midpalatal suture
and cervical vertebral maturation staging (CVMs).
In this study, 24 patients with posterior skeletal cross-bite were
treated at Orthodontics Department-Faculty of Dentistry in Hama
University. Hyrax expansion device was applied in all patients and
the results were assessed after active expansion
The purpose of this study was to evaluate the changes of
airway dimensions following functional and camouflage treatment in Class
II Division 1 malocclusion.
