Authors’ response
We appreciate the interest and comments of Dr Sabour regarding our recent article “Prediction of 3-dimensional pharyngeal airway changes after orthognathic surgery: A preliminary study” (Brunetto DP, Velasco L, Koerich L,…
Prediction of 3-dimensional pharyngeal airway changes after orthognathic surgery: A methodological issue
I was interested to read the article by Brunetto and colleagues published in the September 2014 edition of the Journal . The purpose of the authors was to correlate the…
Nonextraction treatment of a skeletal Class III adolescent girl with expansion and facemask: Long-term stability
This article describes the combined use of maxillary expansion and a protraction facemask in the correction of a skeletal Class III malocclusion after the patient’s pubertal growth spurt. Treatment efficacy…
January 1, 1915, revisited
It is a chilly overcast day in St Louis, much like it was 100 years ago today. I am standing near the corner of Grand Avenue and Olive Street, looking east…
How to test validity in orthodontic research: A mixed dentition analysis example
Introduction The data used to test the validity of a prediction method should be different from the data used to generate the prediction model. In this study, we explored whether…
Correction of a skeletal Class II malocclusion with severe crowding by a specially designed rapid maxillary expander
To correct an Angle Class II malocclusion or to create spaces in the maxillary arch by nonextraction treatment, distal movement of the maxillary molars is required. Various modalities for distalizing…
Reliability of linear and angular dental measurements with the OrthoMechanics Sequential Analyzer
Introduction The aim of this study was to evaluate the reliability of newly developed software in the assessment of orthodontic tooth movement 3 dimensionally. Methods The sample consisted of pretreatment…
Maxillary arch perimeter prediction using Ramanujan’s equation for the ellipse
Introduction The prediction of arch perimeter gained when expanding the arch or proclining the anterior incisors is particularly important in the decision of tooth extraction vs nonextraction therapy for orthodontic…

J. Daniel Subtelny To date, only 1 person has been awarded the 4 highest honors given by the orthodontic specialty in the United States. In 1959, Dr J. (Jacob) Daniel…
Comparative analysis of upper airway volume with lateral cephalograms and cone-beam computed tomography
Introduction In this study, we aimed to evaluate the adenoidal nasopharyngeal ratio (ANR) on lateral cephalograms by assessing upper airway volumes using cone-beam computed tomography (CBCT) images as the validation…
