يعتبر تضيق الفك العلوي من الاضطرابات الهيكلية الشائعة وقد تعددت التقنيات الجراحية المستخدمة في معالجة تضيق الفك العلوي عند البالغين وإحدى هذه التقنيات هي تقنية التوسيع الفكي المساعد جراحياُ الذي اختلفت حوله الدراسات من حيث التقنية الجراحية والتأثيرات الهيكلية والسنية السنخية الناجمة عنه
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.

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.
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 .
Distalizition of the upper first Molar is a common treatment modality and
very important method to correct Distal Malocclusion, or to create Spaces
in the upper arch.
The Distal Jet has recently been proposed to distalize maxillary molars in
Class II cases with no need for patient cooperation.
Orthodontic treatment is considered successful only if optimal esthetic and
function are achieved.The objective of this study was to compare facial soft tissue profile changes
produced by a new technique (elastic forces based on skeletal anchorage
mini-plates) with changes
produced by conventional class-II elastic forces.
