Editor’s Comment and Q&A
Introduction White spots (WS) related to orthodontic treatment are severe cariologic and cosmetic complications, but they are shown to be partially reduced by remineralization or abrasion in short-term follow-ups. In…
Self-ligating bracket claims
Although the self-ligating edgewise bracket was introduced to orthodontists 75 years ago, recent advances in bracket technology have resulted in a number of new self-ligating bracket “systems” and greater interest…
Teaching orthodontic residents and clinicians about cleft palate treatment
Thank you for your comments (Turpin DL. Editor’s comment. Am J Orthod Dentofacial Orthop 2010;137:578) on my Guest Editorial in the May issue (Berkowitz S. The need to establish an…
Is the education worth the debt?
The average debt of a graduating orthodontist is about $250,000, but for some the figure exceeds $600,000. Depending on interest rates, these young orthodontists will pay thousands of dollars a…
Cone-beam computed tomography evaluation of mini-implants after placement: Is root proximity a major risk factor for failure?
Introduction The purposes of this study were to determine factors favoring successful mini-implant placement and to evaluate root proximity as a possible risk factor for failure of osseointegration-based mini-implants during…
Multidisciplinary approach for a patient with dentinogenesis imperfecta and anterior trauma
Dentinogenesis imperfecta is an inherited dentinal dysplasia involving several risks for orthodontic treatment. This case report describes the multidisciplinary treatment of a 17-year-old girl whose Class II Division 1 malocclusion…
Effect of arch form on the fabrication of working archwires
Introduction Previous studies have shown that most practitioners plan to maintain intercanine and intermolar widths during orthodontic treatment with fixed appliances. The aim of this study was to determine whether…
Three-dimensional surgical simulation
In this article, we discuss the development of methods for computer-aided jaw surgery, which allows us to incorporate the high level of precision necessary for transferring virtual plans into the…
Short-root anomaly in an orthodontic patient
Short-root anomaly is a rare condition, but it can be a problem for orthodontists and their patients. Our aim in this article was to report the treatment of an orthodontic…
Treatment and posttreatment effects of a facial mask combined with a bite-block appliance in Class III malocclusion
Introduction In this cephalometric investigation, we analyzed the treatment and posttreatment effects of an orthopedic protocol for Class III malocclusion consisting of a facial mask combined with a removable bite-block…
Volumetric, planar, and linear analyses of pharyngeal airway change on computed tomography and cephalometry after mandibular setback surgery
Introduction The purpose of this study was to use lateral cephalometry and computed tomography (CT) to examine the volumetric, planar, and linear changes in the pharyngeal airway after mandibular setback…
Mucoepidermoid carcinoma diagnosed in orthodontic patients
A detailed clinical examination is important for early diagnosis of oral lesions in every dental specialty, including orthodontics, particularly because these patients are constantly checked during orthodontic treatment. This report…
Measurement of friction forces between stainless steel wires and “reduced-friction” self-ligating brackets
Introduction In this study, we assessed the friction forces between various self-ligating brackets and stainless steel orthodontic wires, subjected to different shear and bending forces in the buccolingual plane. Methods…
A new concept of anatomic lingual arch form
Introduction The aim of this study was to describe a natural and anatomic lingual arch form obtained from subjects with normal occlusion that could be used, with other criteria, in…
Distally displaced premolars: A dental anomaly associated with palatally displaced canines
Introduction The aim of this study was to evaluate the significance of association between distally displaced premolars (DDP) and palatally displaced canines (PDC) in the pattern of associated phenotypes of…
