Assessment of vertical changes during maxillary expansion using quad helix or bonded rapid maxillary expander.
OBJECTIVE To determine if there is a significantly different effect on vertical changes during phase I palatal expansion treatment using a quad helix and a bonded rapid maxillary expander in growing skeletal Class I and Class II patients. MATERIALS AND METHODS This retrospective study looked at 2 treatment groups, a quad helix group and a bonded rapid maxillary expander group, before treatmen...
متن کاملFinite Element Analysis of An Automated Rapid Maxillary Expander (ARME)
An Automated Rapid Maxillary Expander (ARME), is a specially designed orthodontic appliance to overcome the shortcomings imposed by the traditional butterfly expansion appliance. It operates by automatically widening the maxilla (upper jaw) by expanding the midpalatal suture [1]. This procedure is not feasible after late teenage years due to more rigid facial skeleton features. According to the...
متن کاملMandibular cervical headgear vs rapid maxillary expander and facemask for orthopedic treatment of Class III malocclusion.
OBJECTIVE To compare the effectiveness of the rapid maxillary expander and facemask (RME/ FM) and mandibular cervical headgear (MCH) protocols when followed by fixed appliances and evaluated at a postpubertal observation in patients with dentoskeletal Class III malocclusion. MATERIALS AND METHODS The sample treated with the RME/FM followed by fixed appliances included 32 patients (12 boys and...
متن کاملSoft tissue profile changes after rapid maxillary expansion with a bonded expander.
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...
متن کاملPreliminary Design of an Automated Rapid Maxillary Expander for Dento-facial Application
INTRODUCTION The objective of maxillary expansion is to correct maxillo mandibular transverse discrepancies by skeletal (orthopedic) expansion of the maxilla while avoiding any dental side effects. [1]. For a rapid maxillary expansion (RME) device, the expansion of maxilla is accomplished through heavy forces that are capable of separating the midpalatal suture at the rate of 0.2 to 0.5mm per d...
