يعد تضيق الفك العلوي أحد أشكال سوء الإطباق المشاهدة في الممارسة السريرية اليومية، الذي غالباً ما يترافق مع تضيق في مجرى التنفس الأنفي. استخدمت عدة طرائق لتوسيع الفك العلوي و معالجة هذا الخلل، من بينها تقنية التوسيع البطيء للفك العلوي بقوة خفيفة و تقنية التوسيع السريع. هدفت هذه الدراسة إلى تقييم التغيرات في عرض التجويف الأنفي الناتجة عن توسيع الفك العلوي بالتوسيع البطيء بجهاز SPRING JET II في المرحلة الثانية من الإطباق المختلط، و مقارنتها بمثيلاتها الناتجة عن التوسيع السريع للفك العلوي باستخدام موسعة HYRAX.
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 maxillary 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 .

The aim of this study is to evaluate the healing after
apicectomy by using two different techniques. And to evaluate the
effect of MTA as a retrograde filling material and also the Er:YAG
laser as a tool for resecting the apex, and the influence of them in
the healing.
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 current study aimed to examine the effects of the modified tandem
appliance on the dimensions of the airways.
Pretreatment and post-treatment cephalograms of twelve patients with
maxillary deficiency, (7 girls, 5 boys; mean age 8±0.5 years), w
ho were
seeking treatment at the Department of Orthodontics, Damascus
University, were studied. These patients were treated using the modified
tandem appliance with rapid maxillary expansion.
To determine the stability of transverse skeletal
