The aim of this study was to investigate long-term effects induced by rapid maxillary expansion (RME), followed by comprehensive orthodontic treatment, in a sample of 42 patients compared with normal growth changes in a sample of 20 subjects. Treated subjects underwent Haas-type RME with 2 turns a day (0.25 mm per turn) until the expansion screw reached 10.5 mm (about 21 days). The Haas expande...

INTRODUCTION Prognosis is the main limitation of interceptive treatment of Class III malocclusions. The interceptive procedures of rapid maxillary expansion (RME) and face mask therapy performed in early mixed dentition are capable of achieving immediate overcorrection and maintenance of facial and occlusal morphology for a few years. Individuals presenting minimal acceptable faces at growth co...

We consider a family of random matrix ensembles (RME) invariant under similarity transformations and described by the probability density P (H) = exp[−TrV (H)]. Dyson’s mean field theory (MFT) of the corresponding plasma model of eigenvalues is generalized to the case of weak confining potential, V (ǫ) ∼ A2 ln(ǫ). The eigenvalue statistics derived from MFT are shown to deviate substantially fro...

Introduction: Maxillary constriction is a dentoskeletal deformity characterized by discrepancy in maxilla/mandible relationship in the transverse plane, which may be associated with respiratory dysfunction. Objective: The objective of this study was to evaluate the skeletal effects of RME on maxillary and nasal transverse dimensions and compare the differences between males and females. Me...

The aim of this study was to evaluate the short- and long-term treatment effects of rapid maxillary expansion (RME) on the soft tissue facial profile of subjects treated with a modified acrylic-hyrax device. The sample comprised 10 males and 10 females in the mixed dentition. Their average age was 9.3 years ± 10 months pre-treatment (T1), with a narrow maxilla and posterior crossbite, treated w...

The aim of this study was to assess by means of cone-beam computed tomography (CBCT) scans the transverse effects on the nasomaxillary complex in patients submitted to rapid maxillary expansion (RME) using Haas expander in comparison to untreated individuals. This prospective controlled clinical study assessed 30 subjects (18 boys and 12 girls) with mixed dentition and during pubertal growth. T...

<p>Realistic Mathematics Education (RME) is an instructional theory that has been implemented in many countries around the world to link mathematics real-world situations. The effectiveness of implementing RME education highly dependent on role teachers. This study was conducted with 64 high school teachers survey their understanding and perspectives status implementation teaching topics ...

Research in both ICT and RME is expanding at a breakneck pace. The growth of research engineering can be tracked by one type analysis known as bibliometric analysis. This used to identify the number scholarly publications on RME. study quantitative descriptive nature. Researchers are interested examining development RME, well distribution pattern Scopus, which based affiliations, themes, scient...

The purpose of this article is to describe how, within the Dutch approach to mathematics education, called Realistic Mathematics Education (RME), models are used to elicit students’ growth in understanding of mathematics. First some background information is given about the characteristics of RME related to the role of models in this approach. Then the focus is on the use of the bar model withi...
