OBJECTIVE The aim of this study was to evaluate the effects of upper incisors and canine angulations introduced by different bracket prescriptions on dental arch perimeter. MATERIALS AND METHODS Cone beam computerized tomography scans collected using I-Cat (Imaging Sciences International, Hatfield, PA, USA) were selected conveniently from a database of routine exams of a clinical radiology ce...

The changes in soft tissue profile for 66 Angle's Class III malocclusion subjects treated either with the Function Regulator, or Upper Removable Appliances, or the Edgewise Appliance were assessed by comparing cephalometric radiographs taken before and after correction of the anterior occlusion. While the mean soft tissue profile in all groups improved in relation to a Control Group, the FR.III...

INTRODUCTION The objectives of this research were to assess skeletal and dental changes in patients with Class II malocclusion treated with the edgewise crowned Herbst appliance in the early mixed dentition and to measure the stability of treatment after a second phase of fixed appliance therapy. METHODS Twenty-two patients (ages, 8.4 ± 1.0 years) with Class II Division 1 malocclusion treated...

This case report presents an adult skeletal Class III and open-bite malocclusion case treated without surgical intervention using fixed edgewise technique, reverse headgear, and Class III and anterior box elastics. The patient was a 16-year-old Turkish female who had completed her growth and development. She had a four mm open bite, maxillary retrognathia, a crossbite in the anterior and left p...

This was a retrospective, longitudinal cephalometric and cast study of 29 white patients at pretreatment, posttreatment, and an average of 6 years 3 months postretention. The goal was to assess changes with treatment and retention with the expanding mandibular lingual arch appliance in conjunction with fixed edgewise treatment. Seven mandibular cast measurements were assessed, including arch cr...

In an orthodontic treatment during the permanent dentition period of patients with skeletal class Ⅲ malocclusion, it is sometimes difficult to decide which treatment, or without orthognathic surgery, better. For cleft lip and palate, we consider not only discrepancy between maxillary mandibular morphology but also other factors including number congenitally missing teeth, abnormal in soft tissu...
