Editor’s Comment and Q&A
Introduction Study models are an essential part of an orthodontic record. Digital models are now available. One option for generating a digital model is cone-beam computed tomography (CBCT) scanning of…
Editor’s Comment and Q&A
Introduction Computer software can be used to predict orthognathic surgery outcomes. The aim of this study was to subjectively compare the soft-tissue surgical simulations of 2 software programs. Methods Standard…
Changes in esthetic standards since 1940
Introduction The goals of this study were to investigate differences between the most popular female and male faces, past and present, and to determine whether they had changed over time…
Comparative study of 2 software programs for predicting profile changes in Class III patients having double-jaw orthognathic surgery
Introduction Computer software can be used to predict orthognathic surgery outcomes. The aim of this study was to subjectively compare the soft-tissue surgical simulations of 2 software programs. Methods Standard…

Soft-tissue considerations in mandibular setback
In the September issue, “Surgical orthodontic treatment for a patient with advanced periodontal disease: Evaluation with electromyography and 3-dimensional cone-beam computed tomography” (Nakajima K, Yamaguchi T, Maki K. Am J…
Authors’ response
A clinically useful measurement must be reproducible. Drs McNamara, Baccetti, and Franchi claim that the CVM method has high reproducibility. They claim interoperator (between each other) agreement of 98.6% and…
Reproducibility of the CVM method: A reply
We read with obvious interest an article published online in October 2009 about the reproducibility of the cervical vertebral maturation (CVM) method (Gabriel DB, Southard KA, Qian F, Marshall SD,…
Authors’ response
Thank you for this opportunity to reply to Dr Katz’s letter, published in the January issue (Katz MI. Appearances count when industry underwrites research. Am J Orthod Dentofacial Orthop 2010;137:3-4),…
AAO research award winners recognized
The Council on Scientific Affairs (COSA) recently announced its selection of the best basic science and clinical research studies submitted by US and Canadian postgraduate orthodontic programs. Plan to hear…
Biomechanics of self-ligating brackets
One of the hottest subjects in town is the difference between self-ligating and conventional brackets, especially from the biomechanical point of view. We applaud the group from Edmonton, Alberta, Canada,…
Cranial base superimposition for 3-dimensional evaluation of soft-tissue changes
Introduction The recent emphases on soft tissues as the limiting factor in treatment and on soft-tissue relationships in establishing the goals of treatment has made 3-dimensional (3D) analysis of soft…
Mixed unilateral transposition of a maxillary canine, central incisor, and lateral incisor
A girl, aged 7 years 11 months, came for treatment with the chief complaint of lack of eruption of her maxillary right central and lateral permanent incisors. The radiographic analysis…
Treatment of a horizontally impacted mandibular canine in a girl with a Class II Division 1 malocclusion
When a patient has an impacted tooth, the timing of orthodontic treatment, the type of surgical procedure to expose the tooth, the orthodontic mechanics, and the potential problems vary depending…
Multiple bilateral impactions in an adolescent girl
This article describes a patient whose permanent canines and premolars had not erupted at age 14 years, although their root formation was complete, with closed apices. Surgical and orthodontic treatment…
Four curious cases of cone-beam computed tomography
Cone-beam computed tomography (CBCT) has become popular, and its many inherent advantages are indisputable. Nevertheless, CBCT is prescribed cautiously because the radiation dosage is higher than that of conventional radiography….
Considerations in the use of cone-beam computed tomography for buccal bone measurements
Cone-beam computed tomography (CBCT) has become a popular modality in research, but it can be misused and misunderstood. Several image quality, bone biology, and statistical factors must be considered before…
