Maxillary protraction headgear has been used in the treatment of Class III malocclusion with maxillary deficiency. However, loss of dental anchorage has been reported with tooth-borne anchorage such as lingual…
Introduction The aim of this article was to assess the effect of wire adaptation on the lingual surfaces of mandibular anterior teeth with 3 types of lingual retainers on the…
Introduction The purpose of this article was to histologically evaluate root resorption and repair after orthodontic intrusion with different force magnitudes and fixed anchorage. Methods A randomized split-mouth repeated-measure design…
Introduction The aim of this study was to analyze the current literature for the best evidence (randomized clinical trials) about the efficacy of functional appliances on mandibular growth in the…
Orthodontic appliances that become dislodged can cause problems in the airway or the gastrointestinal tract. Accidental ingestion of an appliance during a chair-side procedure or because of inadequate retention of…
This case report demonstrates the efficient use of implant anchorage in a patient with mesially inclined mandibular molars and an overerupted maxillary molar. A 14-year-old girl had an overerupted maxillary…
Introduction Orthodontists assess mesiodistal root angulations before, during, and after orthodontic treatment as an aid in establishing proper root position. Panoramic imaging has been useful for this purpose and is…
Introduction The long-term stability of posterior crossbite correction in the mixed dentition has not been sufficiently evaluated. Our aim was to compare long-term outcomes in patients with crossbite correction by…
Introduction The purposes of this study were to determine the incidence of open gingival embrasures after a single mandibular incisor extraction and to investigate whether age, sex, interproximal pretreatment and…
The introductory chapter describes the physical laws of mechanics governing forces and motions in the context of orthodontics. Described are concepts such as moments and couples, centers of resistance, center…
A reader recently sent me this letter. Doc: I probably spend more time doing consultations before braces than anyone. It really bugs my staff, but I view it as relationship…
Attaining Board Certification should be a goal of every orthodontic resident, orthodontic educator, and practicing orthodontist. The Board Certification process requires commitment, persistence, firmness of purpose, and sacrifice. Procrastination is…
Introduction The influence of the forces exerted by the perioral musculature on the position of the teeth has been the object of many scientific studies. Of the forces from the…
Introduction The American Board of Orthodontics’ discrepancy index (DI) was designed to objectively quantify the complexity of a malocclusion before orthodontic treatment. In this study, we assessed the influence of…
Introduction The aims of this study were to compare blood parameters and periodontal characteristics of orthodontic patients allergic to nickel with those of nonallergic patients and to determine the correlation…
Introduction Computer-based smile esthetic surveys based on slider technology allow more precise control of variables and the possibility of obtaining continuous data. Variations in the perception of smiles from different…
Introduction Axial rotation of orthodontic wire produces buccal or lingual root movement and is often referred to as third-order movement or “torque expression.” The objective of this study was to…
Introduction Electron-beam irradiation can be used to influence the properties of polymers. Electron beams cause cross-linking that enhances the molecular mass of the polymer; this leads to branched chains until,…
Introduction Our objective was too assess the effectiveness of 3 analgesics (ibuprofen, naproxen sodium, and acetaminophen) and a placebo administered before and after the placement of separators in reducing the…
Introduction The aim of this community-based trial was to compare the effectiveness of the quad-helix appliance and removable plates for treating posterior crossbite. Methods Ninety-nine patients were randomly divided into…
