ObJECTivE: To evaluate and compare the effectiveness of rapid maxillary expansion (RME) and slow maxillary expansion (SME). MaTERiaLS aND METHODS: PubMed, Embase, Web of Science, CENTRaL, ProQuest Dissertations & Theses, ClinicalTrial.gov, and SiGLE were searched from January 1980 to October 2012 for randomized or nonrandomized controlled trials. The processes of study search, selection, and qu...

The stability of rapid maxillary expansion (RME) was studied in 20 patients. Study models were evaluated immediately prior to treatment, at the end of treatment, and at least 4 years post-treatment with regards to maxillary and mandibular intermolar widths, intercanine widths, arch perimeters, and irregularity indices. The mean maxillary intermolar width increased by 3.7 mm during treatment, an...

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...

OBJECTIVE To evaluate early maxillary arch changes in infants with complete bilateral cleft lip and palate (BCLP), using a simple measurement technique. MATERIAL AND METHOD A measurement model technique simplified from previously reported methods was used to analyze early maxillary changes of four non-syndromic complete BCLP. Study models of these cases were evaluated before presurgical ortho...

A patient in the early mixed dentition was experiencing "difficulty in eating." The right mandibular posterior teeth were telescoped within the maxillary arch. The mandibular midline deviated to the left of the maxillary midline. With the midlines aligned, posterior occlusion was minimal. By activating a lingual arch, the mandibular arch width was increased to establish a posterior occlusion. A...

The purpose of this longitudinal study was to evaluate the short- and long-term changes in dental arch dimensions in patients treated with rapid maxillary expansion (RME) followed by fixed edge-wise appliances. The records of 112 patients in the treated group (TG) were compared with those of 41 untreated controls. Serial dental casts were available at three different intervals: pretreatment (T1...

The purpose of this study was to assess the prevalence of permanent incisor crowding in the maxillary and mandibular arches among Saudi schoolchildren. Three hundred and fifty four dental casts of Saudi schoolchildren attending pediatric dentistry and orthodontic clinics in College of Dentistry at King Saud University in Riyadh, Saudi Arabia were studied by one examiner. The children’s age rang...

INTRODUCTION The aim of this prospective longitudinal clinical study was to evaluate the short-term and long-term changes in dental-arch dimensions in patients treated with either an acrylic splint rapid maxillary expander alone (RME-only) or a rapid maxillary expander combined with a mandibular removable Schwarz plate (RME-Sz) in the early mixed dentition, followed later by fixed appliances in...

A case report of 16 years female who reported to department with chief complaint of irregularly placed front teeth and an unpleasant smile. Patient was diagnosed with class II div 2 malocclusion with arch length discrepancy of 8.5 mm in maxilla with buccally placed maxillary canines. Molar distalization technique was planned using pendulum appliance. Molars were distalized by 5 mm in the right,...

OBJECTIVES The objective of the present systematic review was to test the hypothesis of no difference in transverse skeletal and dental arch expansion and relapse after segmental Le Fort I osteotomy versus surgically assisted rapid maxillary expansion. MATERIAL AND METHODS A MEDLINE (PubMed), Embase and Cochrane library search in combination with a hand-search of relevant journals was conduct...
