Maxillary expansion: a meta analysis

Clinical Orthodontics and Research, 2001
The 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 ...

Comparative characterization of maxillary expansion and alternate maxillary expansions and constrictions in rats

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.

[Therapeutic maxillary expansion].

Revue belge de medecine dentaire, 1992
The 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 ...

Experimental Expansion of the Maxillary Sinus

Journal of Craniofacial Surgery, 1994
To 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.

The stability of maxillary expansion

Australian Dental Journal, 1977
Abstract— 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, 1987
There 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.

[Surgically assisted maxillary expansion].

Nederlands tijdschrift voor tandheelkunde, 2001
Orthodontic expansion of the maxilla can be facilitated by bone cuts through the zygomatic-alveolar process and in the palate lateral of the nasal septum. Stability of the surgical-orthodontic treatment outcome depends on the equilibrium of forces of the tongue and cheeks (functional envelope). Long term, even lifetime, retention is advised.
