Camouflage of a high-angle skeletal Class II open-bite malocclusion in an adult after mini-implant failure during treatment
The treatment of skeletal anterior open-bite malocclusion requires complex orthodontic planning that considers its multifactorial etiology, treatment limitations, and high relapse rates. This case report illustrates a successful treatment approach…
Timing of orthognathic surgery on the changes of oral health-related quality of life in Chinese orthognathic surgery patients
Introduction Although the association between orthognathic surgery and oral health-related quality of life (OHRQoL) has been explored, few studies have been carried out to describe the influence of surgery type…
Directed acyclic graphs: A tool to identify confounders in orthodontic research, Part II
In the previous article, we discussed the problem of confounding and presented 3 fundamental methods for assessing and adjusting for confounders: the traditional approach, the noncollapsibility approach, and the directed…
Twenty-year follow-up of a familial case of PTH1R-associated primary failure of tooth eruption
Introduction Nonsyndromic primary failure of eruption (PFE) is a rare autosomal dominant disorder of dental eruption with no obvious dental or soft tissue interference. The purposes of this study were…
Accuracy and head positioning effects on measurements of anterior tooth length using 3-dimensional and conventional dental panoramic radiography
Introduction The purposes of this study were to examine the accuracy and the head positioning effects on measurements of anterior tooth length using 3-dimensional (3D) and conventional dental panoramic radiography…
Orthodontic uprighting of a horizontally impacted third molar and protraction of mandibular second and third molars into the missing first molar space for a patient with posterior crossbites
A 22-year-old woman came with a unilateral missing mandibular first molar and buccal crossbite. The open space was closed by protraction of the mandibular left second molar and uprighting and protraction…
Perception of changes in soft-tissue profile after Herbst appliance treatment of Class II Division 1 malocclusion
Introduction In this study, we sought to assess the perception of changes in soft-tissue profile after Herbst appliance treatment by comparing facial profile silhouettes before treatment, immediately after treatment, and…

It is my great honor to review TMD and orthodontics by Sanjivan Kandasamy, Charles Greene, Donald Rinchuse, and John Stockstill. These editors are all well known and have published numerous…
Effects of orthodontic appliances on the diagnostic quality of magnetic resonance images of the head
Introduction The influence of 4 commonly used fixed orthodontic appliances on artifact formation and diagnostic quality of magnetic resonance (MR) images of the head produced by a 3-T MR scanner…
Atorvastatin-induced osteoclast inhibition reduces orthodontic relapse
Introduction The statin class of drugs enhances osteogenesis and suppresses bone resorption, which could be a plausible biologic mechanism for mitigation of orthodontic relapse. We aimed to determine whether atorvastatin…
Safe zones for miniscrews in maxillary dentition distalization assessed with cone-beam computed tomography
Introduction The purpose of this study was to assess the anatomic structure of the buccal alveolar bone in the infrazygomatic crest region with cone-beam computed tomography to locate safe zones…
Associations among sella turcica bridging, atlas arcuate foramen (ponticulus posticus) development, atlas posterior arch deficiency, and the occurrence of palatally displaced canine impaction
Introduction Head and neck skeletal anomalies or normal variants might predict the occurrence of palatally displaced impacted maxillary canines. Despite their clinical importance, studies in this regard are rare, especially…
Candidate gene analyses of 3-dimensional dentoalveolar phenotypes in subjects with malocclusion
Introduction Genetic studies of malocclusion etiology have identified 4 deleterious mutations in genes DUSP6, ARHGAP21 , FGF23 , and ADAMTS1 in familial Class III cases. Although these variants may have…
Force degradation of orthodontic latex elastics: An in-vivo study
Introduction Our objectives were to assess the force degradation of orthodontic latex elastics over 48 hours in vivo and to study the relationship between the amount of mouth opening and the degree…
