Authors’ response
We appreciate the interest of Drs Ye, Li, and Lai in the controversial topic of airway volume assessment with CBCT. Below are our responses to their questions. The aim of…
Evaluating airway volume with CBCT
With interest, we read the Techno Bytes article on analyzing airway volume by using cone-beam computed tomography (CBCT) in the May 2012 issue of the AJO-DO . The authors used…
Esthetic periodontal surgery for impacted dilacerated maxillary central incisors
Clinicians do not frequently see impacted dilacerated maxillary incisors in their patients. When they do, there are several diagnostic and management challenges for correcting root dilacerations. An unfavorable esthetic outcome might…
Three-dimensional ultrashort echo magnetic resonance imaging of orthodontic appliances in the natural dentition
Introduction The purpose of this study was to determine whether ultrashort echo time magnetic resonance imaging technology could be used to image teeth with orthodontic appliances in place. Methods High-resolution…
Functional improvements after orthodontic-surgical reconstruction in a patient with multiple maxillofacial fractures
Patients with multiple craniofacial fractures often suffer from stomatognathic problems after their primary treatment, because administering emergency care is the clinician’s highest priority. Therefore, optimal bone repositioning is sometimes difficult…
Treatment effects of bonded spurs associated with high-pull chincup therapy in the treatment of patients with anterior open bite
Introduction The aim of this prospective clinical study was to investigate the cephalometric changes produced by bonded spurs associated with high-pull chincup therapy in children with Angle Class I malocclusion…
Orthodontic correction of a transposed maxillary canine and first premolar in the permanent dentition
The patient was a 16-year-old Japanese girl whose chief complaints were crowding and transposition of the maxillary canine and first premolar. A setup model was used to preoperatively align the…
Severe facial asymmetry and unilateral lingual crossbite treated with orthodontics and 2-jaw surgery: 5-year follow-up
A 33-year-old woman with severe facial asymmetry and unilateral lingual crossbite was treated with orthodontics combined with differential maxillary impaction and intraoral vertical ramus osteotomy. After 12 months of preoperative…
Bone stress when miniplates are used for orthodontic anchorage: Finite element analysis
Introduction The success rate of miniplates is superior to that of other temporary anchorage devices; nevertheless, the biomechanical behavior of miniplates during orthodontic use is not totally understood. The aim…
Finite element analysis of the effect of force directions on tooth movement in extraction space closure with miniscrew sliding mechanics
Introduction Miniscrews placed in bone have been used as orthodontic anchorage in extraction space closure with sliding mechanics. The movement patterns of the teeth depend on the force directions. To…
