Arch width Changes with a Rapid Maxillary Expansion Appliance Anchored to the Primary Teeth

Expansion of the lower arch concurrent with rapid maxillary expansion.

The effect of rapid maxillary expansion on the mandibular intercanine and intermolar widths during treatment and its stability after retention was studied. In addition, the relationships between the interarch change and the facial types and ages of the subjects of the sample were evaluated. The sample consisted of 17 cases for the study of intercanine width, and 22 nonextraction cases for the s...

Rapid maxillary expansion using bone anchored Hybrid Hyrax appliance in adolescent females

Comparison of dental arch and arch perimeter changes between bonded rapid and slow maxillary expansion procedures.

The purpose of this study was to evaluate and compare the dental effects of bonded rapid maxillary expansion (RME) and bonded slow maxillary expansion (SME) treatment methods. Subjects with a maxillary bilateral crossbite were selected and two treatment groups each with 12 patients were constructed. At the beginning of treatment, the average chronological ages were 11.96 years for the RME group...

Digital evaluation of nasal changes induced by rapid maxillary expansion with different anchorage and appliance design

BACKGROUND Scientific evidence showed that rapid maxillary expansion (RME) affects naso-maxillary complex, increasing nasal width and volume. This study aimed to evaluate nasal changes induced by rapid maxillary expansion with different anchorage and appliance design by using low dose and cone beam computed tomography. METHODS A total of 44 patients (20 males, mean age 8y 8 m ± 1y 2 m; 24 fem...

Force Analysis of an Automated Rapid Maxillary Expansion (ARME) Appliance

An Automated Rapid Maxillary Expander (ARME) is a specially designed microcontroller-based orthodontic appliance to overcome the shortcomings imposed by the traditional maxillary expansion appliances. This new device is operates by automatically widening the maxilla (upper jaw) by expanding the midpalatal suture [1]. The ARME appliance that has been developed is a combination of modified butter...
