Skeletal and Dentoalveolar Changes Following Surgically Assisted Rapid Maxillary Expansion by Using Buccal Corticotomy with Two Palatal Osteotomies ( Comparative Clinical and Radiographic 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.

A Study of Nasal Cavity Width Change after Maxillary Expansion Using two Different Techniques

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 .
