Introduction Compared to the conventional approach to orthognathic surgery, “surgery first” protocols could be advantageous in terms of shortened treatment times and immediate esthetic improvement. However, consensus regarding patient selection,…
David is your sister’s only child and the son of 2 physicians. You’ve been a big part of his life and consequently have developed a special relationship with him. This…
We want to thank the authors for reporting a novel approach for rapid maxillary expansion (RME) in skeletally mature patients (Echchadi ME, Benchikh B, Bellamine M, Kim SH. Corticotomy-assisted rapid…
The special section, “100 years of orthodontic history,” published in the December 2015 issue of the AJO-DO , delineates the important events in the past 100 years of orthodontics and provides a…
The letter from Dr Frey raised several points worthy of discussion. First was the question of differential species sensitivity to botulinum toxins and whether rabbits are an appropriate model for…
A 2011 study from the University of Michigan’s Department of Orthodontics reflects on the problem of caries in children undergoing orthodontic treatment: “This widespread problem…is an alarming challenge and warrants…
I hope that readers opening the December 2015 issue were not surprised to find that unilateral paralysis of masseter muscles in growing rabbits should have an effect on hard tissue…
Introduction Agenesis of a maxillary lateral incisor occurs in about 2% of the population. Treatment options should adapt to natural biologic changes in a lifelong perspective. Methods and results A…
We successfully treated a 32-year-old woman who had facial asymmetry and unilateral mandibular condylar osteochondroma using ipsilateral mandibular condylectomy and contralateral ramus osteotomy. Mirror image analysis with a noncontact 3-dimensional…
Introduction In this study, we evaluated the reproducibility of the lip position at rest in 3 dimensions using reverse engineering software and stereophotogrammetric images. Methods We used 3dMD Flex (3dMD,…
This case report describes the use of a microimplant-assisted rapid palatal expansion (MARPE) appliance to orthopedically correct a transverse maxillary deficiency in an adult patient. Expansion forces transmitted through the…
Fig Tadao Nakago Tadao Nakago died of bladder cancer on February 12, 2016, just 2 days before his 83rd birthday. He was born on February 14, 1933, in Sanda, north of…
In the simple linear regression model, we used a continuous outcome (days to align) and a single continuous predictor (irregularity index). The flexibility of the multiple regression model allows us…
A reader wrote me the following. Larry, do you have any insight into the gray area dealing with the transition from phase 1 (early treatment) to phase 2 (secondary treatment)?…
Introduction Although rapid maxillary expansion has been extensively studied in noncleft patients, scarce evidence of maxillary effects is found for patients with oral clefts. Our objective was to evaluate the…
Asymmetries are among the most challenging problems in orthodontics. Proper diagnosis is critical to discern first whether the asymmetry is dental or skeletal. If it is dental, one must then…
Introduction Mandibular retrognathism may be the result of a developmental abnormality or the unfavorable positional relationship of developing jaws. Several lines of evidence suggest that muscles are known to have…
Introduction Tumor necrosis factor alpha (TNF-α) levels are significantly upregulated in the synovial fluid of patients with temporomandibular joint disorder (TMD). The TNF-α influences pain generation and maintenance. Therefore, the…
Introduction Pharynx dimensions may vary according to the position and morphology of the mandible. The aim of this study was to test the hypothesis that craniofacial morphology affects pharyngeal volume…
Introduction The aims of this study were to evaluate how head orientation interferes with the amounts of directional change in 3-dimensional (3D) space and to propose a method to obtain…
