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).
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.
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.
This study aimed to evaluate the effect of associating the application
of Erbium-YAG laser with rapid palatal expansion in adult patients.
Twenty four subjects aged between 13 - 21 years were randomly
assigned to either laser group (n=12) and cont
rol - traditional
treatment with RPE- group (n=12). Laser group patients were
undergone mucosal-bony perforations along midpalatal suture for
three interventions (one a month) by Erbium-YAG laser, and two
bands hyrax expander were cemented for all patients of groups.
Impressions were taken for all patients and dental changes post
activation and retention phases were collected and compared for
both groups.
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 .
