OBJECTIVE The aim of this study was to evaluate and compare the effects of rapid maxillary expansion (RME) and surgically assisted RME (SARME) in the sagittal, vertical, and transverse planes. STUDY DESIGN Orthodontic records of 28 patients were selected retrospectively and divided into two treatment groups. Group 1 comprised 14 patients (4 boys, 10 girls, mean age 14.2 ± 0.74 years) who had ...

The precise role of maxillary constriction in the pathophysiology of obstructive sleep apnea (OSA) is unclear. However, it is known that subjects with maxillary constriction have increased nasal resistance and resultant mouth-breathing, features typically seen in OSA patients. Maxillary constriction is also associated with alterations in tongue posture which could result in retroglossal airway ...

BACKGROUND Aim of this retrospective observational study was to compare upper and lower dental changes in patients treated with Rapid Maxillary Expansion (RME) and Mixed Maxillary Expansion (MME), assessed by dental cast analysis. METHODS Treatment groups consisted of 42 patients: the RME group (n = 21) consisted of 13 female and 8 male subjects with the mean age of 8.8 years ± 1.37 at T0 and...

PURPOSE The purpose of this study was to assess the effectiveness of rapid maxillary expansion (RME) vs simply monitoring the eruption of permanent maxillary incisors following the surgical removal of obstacles to their eruption (supernumerary teeth, odontomas). METHODS Following surgical removal of the obstacles to incisor eruption (T1), 62 patients were randomly assigned to either the group...

Rapid maxillary expansion (RME) is a dentofacial orthopedic treatment procedure which has been routinely used to correct transversal maxillary skeletal and/or dental constriction. Application of RME not only expands the constricted maxilla but also results in an increase in nasopharyngeal airway dimensions, improvement in nasal respiration in patients with abnormal breathing patterns, and bette...

OBJECTIVE To analyse the changes in nasal air flow and school grades after rapid maxillary expansion (RME) in oral breathing children with maxillary constriction. MATERIAL AND METHODS Forty-four oral breathing children (mean age 10.57 y) underwent orthodontic RME with a Hyrax screw. Forty-four age-matched children (mean age 10.64 y) with nasal physiological breathing and adequate transverse m...

BACKGROUND The aim of this pilot randomized controlled trial (RCT) was to evaluate the sagittal mandibular response induced by rapid maxillary expansion (RME) therapy in mixed dentition patients with class II malocclusion, comparing the effects of bonded RME and banded RME with a matched untreated class II control group. METHODS This RCT was designed in parallel with an allocation ratio of 1:...

AIMS AND OBJECTIVES The purpose of the study was to assess the skeletal and dental effects of fan-type rapid maxillary expansion (RME) appliance and Hyrax RME appliance on the craniofacial structures. MATERIALS AND METHODS The sample of the study included 12 patients with constricted maxillary arches. Acrylic bonded type of attachment was used for both groups. Changes in sagittal, vertical, a...

Down syndrome (DS) is the most common aneuploid chromosomal disorder at birth. Phenotypic characteristics include mental retardation, general hypotonia, pharyngeal hypoplasia, frequently constricted maxillary arch with macroglossia and upper air way obstruction. Generally they have marked language difficulties and a characteristic voice. This prospective study assesses the effects of rapid maxi...

OBJECTIVE To assess, during rapid maxillary expansion, the plaque index (PI) and the gingival index (GI) of patients with unilateral cleft lip and palate(UCLP) using Hyrax (HX) or inverted mini-Hyrax (IMHX) rapid maxillary expanders (RME) considering patients' sex and age. METHODS PI (Quigley Index modified by Turesky et al) and GI (Löe and Silness) of 28 UCLP (11 females; 17 males: aged 8 to...
