معرفة مدى استقرار التغيرات العرضية الهيكلية و السنية التالية للتوسيع الفكي السريع المؤازر بالليزر خلال فترة ستة أشهر. تألفت العينة من 23 مريضاً يعانون من تضيق الفك العلوي و عضة معكوسة أحادية أو ثنائية الجانب.
To determine the stability of transverse skeletal changes following Rapid maxillary expansion (RME) assisted by laser during 6 month period. Materials and Methods: The sample consisted of 23 adults patients with contracting in maxilla and posterior unilateral or bilateral crossbite.

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
period. Cone
beam computed tomography radiograph were taken at the
assessment times.
Results showed that the midpalatal suture width has increased
significantly at all measured areas. The results revealed that
significant tipping in the canines , premolars and molars was
recorded in this study.
Maxillary stenosis is a common skeletal disorder. There are many surgical techniques used to treat maxillary stenosis in adults. One of these techniques is the surgically assisted maxillary expansion technique, around which studies differed in terms of surgical technique and the resulting structural and alveolar effects.
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.
The constriction of Maxilla is considered a common disorder in daily clinical
practice; which is usually accompanied with narrow nasal cavity. Many techniques are used to expand
constricted maxilla; such as slow maxillary expansion and rapid maxill
ary expansion.
The aim of this study is to evaluate changes in nasal cavity width after slow maxillary expansion by using
Spring Jet II expander in late mixed dentition; and to compare them with changes caused by rapid
maxillary expansion using Hyrax expander .
Presence of maxillary septa has been known to be a complicating factor for sinus elevation procedure.
This study was aimed at detecting the prevalence, location and height of antral septa in syrianpopulation and to determine whether there is a relat
ionship between the presence of septa and the absence of upper molars .
A total of 174 sinuses in 87 patients (59 male and 28 female) aged 27 - 51 years were evaluated through a computed tomography scan analysis .
No correlation was observed between the presence of septa and the absence of upper molars.
