The oral-facial region is usually an area of significant concern for the individual, because it draws the most attention from other people in interpersonal interactions and is the primary source of vocal, physical, and emotional communication. As a result, patients who seek orthodontic treatment are concerned with improving their appearance and social acceptance, often more than they are with i...

The aim of this study was to determine whether a force applied in an antero-posterior direction would adequately reduce incisor eruption. This is needed to achieve a constant direction of force which is one of the demands for a good model for studying orthodontic tooth movement. Twenty male Wistar rats aged 11-12 weeks were divided into two equal groups: in the appliance group, a superelastic c...

The following is a clinical case report of a patient whose chief complaint was the presence of generalized spacing in the maxillary anterior segment following orthodontic treatment. After meticulous clinical analyses and discussions of the clinical procedures to be adopted, dental bleaching was performed in both arches with 10% hydrogen peroxide (Opalescence Trèswhite Supreme 10% Hydrogen Perox...

This study describes the course of interdisciplinary treatment for mandibular prognathism in an adult patient with a severe Class III malocclusion and a reverse overjet of 9 mm that involved an orthodontic and surgical orthognathic treatment. The orthodontic treatment involved attaching a fixed appliance to the upper and lower dental arches to prepare the patient for the mandibular surgery. Fol...

Maxillary central incisors impaction is a challenging problem in orthodontics, which has a major effect on dental and facial esthetics. Scientific literature agree on the importance of early diagnosis and appropriate intervention. This is a case report of a 10 year-old boy who presented with impaction of maxillary central incisor related to previous trauma to primary dentition and apparent spac...

The aims of this study were to investigate the intensity, location and duration of patients' discomfort following insertion of orthodontic appliances, and to examine for interactions between patient age, gender, appliance type and the perception of pain. After insertion of orthodontic appliances, 170 patients received eight questionnaires, one they completed and returned after 4 h, then one dai...

OBJECTIVE A study was designed to determine changes in the amplitude of the EMG muscular activity of the Masseter and Temporalis muscles at clench in children with a Class II, division 1 malocclusion treated with the pre-orthodontic Trainer functional appliance, for 12 months. STUDY DESIGN 36 Class II, division 1 malocclusion patients (mean age 7.6 ± 1.3 years) composed the treated group and ...

The aim of the study was to determine the prevalence of white-spot lesions (WSLs) in patients with fixed orthodontic appliances. The cross-sectional study sample consisted of three groups of patients: group I, 59 patients treated orthodontically for 6 months; group II, 64 patients treated for 12 months; group 0 (control), 68 patients examined immediately before appliance placement. All groups w...

Ever since Edward Angle introduced his edgewise appliance in 1925, orthodontic innovators have been working to improve on not only its original design, but also the method of attachment. Our "strap-ups" have evolved from banding to bonding, from labial to lingual, and from metallic to clear. But, as Angle would be pleased to learn, we still call it edgewise.
