The incisive canal is located on the median plane of the maxilla, posterior to the roots of the central incisor. Although the incisive canal is not considered an anatomic structure…
Introduction In this study, we aimed to evaluate the effects of maxillary protraction using traditional labiolingual arches and implant-type protraction devices before orthopedic treatment of patients with skeletal Class III…
Introduction Corticotomy has proven to be effective in facilitating orthodontic tooth movement. There is, however, no relevant study to compare the biomechanical effects of different corticotomy approaches on tooth movement….
Introduction This in-vitro study presents the development and validation of an artificial tooth-periodontal ligament-bone complex (ATPBC) and comparison of its behavior with that of rigid dowels during third-order torque simulation….
Introduction The purpose of this study was to analyze the effect of mesiodistal angulation of the maxillary central incisors on the smiling esthetics in young adults. Methods Frontal smile photographs…
Introduction Our objective was to investigate the effect of low-frequency mechanical vibration (LFMV) on the rate of tooth movement, bone volume fraction, tissue density, and the integrity of the periodontal…
Introduction In this study, we evaluated the reproducibility of natural head position for pitch and roll acquired using 3 methods. Methods The participants were 30 Chinese adults (ages, 23-28 years) who…
The approach to orthodontic diagnosis has changed gradually but steadily over the past 2 decades. The shift away from diagnosis based entirely on hard tissue evaluations has been a result of…

Introduction In some skeletal Class III adult patients with nasomaxillary hypoplasia, the LeFort I osteotomy provides insufficient correction. This case report describes a 20-year-old woman with a combination of nasomaxillary…
When we are making measurements before and after an intervention or at the same time on different sites (split-mouth design) in the same patient, we use a paired t test….
Introduction The smile is a key facial expression, and a careful assessment of the facial profile in smiling is an essential part of a complete orthodontic diagnosis. The aim of…
Introduction Fluoxetine is a widely used antidepressant. Its various effects on bone mineral density are well described. The aim of this study was to evaluate the effect of fluoxetine on…
In the sciences, scholars emerge from time to time to lay down principles and crystallize the information of their day. Such a scholar was Dr Robert Murray Ricketts (1920-2003) (…
Orthodontic practice results in relatively few patient challenges and litigations. This often leads to a false sense of security and encourages orthodontists to optimize practice management techniques that may be at…
Introduction The aim of this study was to assess the incidence of white spot lesions (WSLs) in subjects treated with customized lingual multibracket appliances—separately for maxillary anterior teeth 12 to…
Introduction To obtain the balance and harmony of the soft tissue facial profile in orthodontic treatment, it is necessary to identify the characteristics of overlying soft tissues according to the…
As part of the Centennial Celebration of the AJO-DO , approximately 2500 images published in the Journal between 1915 and 2001 have now been identified, scanned, and cataloged. These images…
The importance of facial esthetics to the practice of orthodontics has its origins at the beginning of our specialty. In 1900, Edward H. Angle believed that an esthetic or a…
