INTRODUCTION The aim of this study was to investigate the effectiveness of vertical-pull chincup (VPCC) therapy during an initial rapid maxillary expansion (RME) phase, followed by a second phase of comprehensive orthodontic therapy in growing subjects with mild-to-severe hyperdivergent facial patterns. METHODS The records of 29 subjects treated with bonded RME combined with VPCC followed by ...

Abstract Background The effect of rapid maxillary expansion (RME) on the upper airway (UA) has been studied earlier but without a consistent conclusion. This study aims to evaluate outcome RME UA function in terms aerodynamic characteristics by applying computational fluid dynamics (CFD) simulation. Methods retrospective cohort consists seventeen cases with two consecutive CBCT scans obtained b...

Aim: The study was to examine rapid maxillary expansion (RME), semi-rapid (SRME), and slow (SME) compare the root resorptions occurring in supporting upper first premolar teeth during treatment by using micro-computed tomography (micro-CT). Methodology: Thirty individuals that required tooth extraction were divided into three groups consisting of 10 for RME, SRME, SME. RME group, molar with hyr...

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...

THE ASSOCIATION BETWEEN OBSTRUCTIVE SLEEP APNEA SYNDROME (OSAS), MAXILLOFACIAL MALFORMATIONS, AND MALOCCLUSIONS HAS ATTRACTED ATTENTION. Many patients with OSAS show craniofacial abnormalities involving both the jaws as well as skeletal structures of the respiratory dynamic space. These aberrations may be apparent very early in life. Nasal septal deviation is known to reduce airflow and increas...

Participating in the International Symposium on Early Orthodontic Treatment allowed me to review our long-term studies of orthodontic and orthopedic intervention in patients in the mixed and early permanent dentition periods who present with tooth size-arch length discrepancies. I hope this brief synopsis of that research will spur the reader to examine our textbook, a short conceptual article ...
