Maxillary expansion: a meta analysis
Orthodontics & Craniofacial Research, 2001The utility of maxillary expansion has been equivocal for more than 100 years. The advent of meta‐analysis and evidence‐based learning has provided an opportunity to look objectively at this treatment modality. Medline was searched from 1978 to 1999 for all studies examining the stability of transverse expansion of the human maxilla using initial ...

The biomechanics of rapid maxillary sutural expansion
American Journal of Orthodontics and Dentofacial Orthopedics, 2000 Micro-displacements (fringe patterns) in the bones of the craniofacial complex as seen through laser holography during midpalatal sutural expansion with the Hyrax appliance are used to define the centers of rotation of the maxillary halves in both the frontal and occlusal views.

Journal of Huazhong University of Science and Technology [Medical Sciences], 2014
The purpose of this study was to evaluate whether the cranial and circumaxillary sutures react differently to maxillary expansion (ME) and alternate maxillary expansions and constrictions (Alt-MEC) in a rat model. Twenty-two male Sprague-Dawley rats (6 weeks old) were used and divided into three groups.

Experimental Expansion of the Maxillary Sinus
Journal of Craniofacial Surgery, 1994To assess the feasibility of "tissue" expansion as a means of midface advancement for correction of hypoplasia, expanders were placed in the left maxillary sinuses of New Zealand White rabbits. Twenty-one animals were used for the study, all of whom underwent implantation of radiopaque dental amalgam markers adjacent to cranial sutures at 9 days of age.

Maxillary transverse expansion
2021Introduction: Maxillary transverse discrepancies are commonly treated with a rapid maxillary expander (RME) with the intention of obtaining skeletal expansion to widen the maxilla. However, as patients become older/skeletally mature, obtaining successful suture separation becomes less likely.

The stability of maxillary expansion
Australian Dental Journal, 1977Abstract— The assessment and treatment by rapid maxillary expansion of 516 cases referred by medical practitioners for the treatment of poor nasal airway is reported. The technique is simple and most suitable for the correction of crossbite and Class III malocclusion and for establishing a nasal airway in habitual mouth breathers with a history of ENT ...

The nasal airway following maxillary expansion
American Journal of Orthodontics and Dentofacial Orthopedics, 1987There have been suggestions that maxillary expansion may be justified on the basis of airway considerations alone. The present study assessed the effects of rapid maxillary expansion and surgical expansion on nasal airway size to determine how useful these techniques are for breathing purposes.

[Therapeutic maxillary expansion].
Revue belge de medecine dentaire, 1992The purpose of this study was to assess the effects of rapid maxillary expansion on nasal airflow studies and mouth breathing habit. 15 children aged from 5 to 12 years underwent rapid palatal expansion for orthodontic abnormalities. Otolaryngologic evaluation, computerized active anterior rhinomanometric measurements and oral myo-functional disorder ...

Effect of Rapid Maxillary Expansion on Voice
Journal of Voice, 2016The purpose of this investigation is to evaluate the effect of rapid maxillary expansion (RME) on the fundamental frequency (F0) and formant frequencies F1-F4.Cross-sectional study.A total of 14 consecutive patients between the ages of 9.6 years and 15 years with a constricted maxilla undergoing RME were included in this study.
