Condylar Position in the Treatment of Obstructive Sleep Apnea with a Mandibular Advancement Device: A Pilot Study.

 To evaluate, through a tomographic analysis, the positional changes of the condyle when using a mandibular advancement device (MAD) for the treatment of obstructive sleep apnea (OSA), and to assess if the condylar positions influence OSA polysomnographic patterns.  Ten OSA patients underwent treatment with an MAD, and polysomnographic and tomographic examinations were performed before therapy (T0) and after MAD placement (T1).  By comparing the T0 and T1 measurements, we observed advancement and extrusion of the condyles in all patients (  < 0.

Relationship between craniofacial and dental arch morphology with pharyngeal airway space in adolescents.

Purpose: The aim of the study was to investigate a possible relationship between pharyngeal airway space, craniofacial variables, and dental arch form in adolescents grouped by sex.

Methods: This cross-sectional study included 108 adolescents aged between 12 and 17 years. Lateral cephalometric radiographs were used to analyze sagittal craniofacial variables and the pharyngeal airway space.

Oropharyngeal complex differences related to sex and occlusal factors in adolescents aged 12-17 years.

Objective: To investigate oropharyngeal complex differences related to sex and occlusal factors in adolescents.

Methods: A cross-sectional study was conducted with 108 patients aged 12-17 years. The oropharyngeal complex was evaluated by imaging exams.

Nonsurgical correction of a severe anterior open bite with mandibular molar intrusion using mini-implants and the multiloop edgewise archwire technique.

This article reports the case of a 24-year-old man with a large anterior open bite, mild mandibular crowding, increased overjet, no passive lip sealing, and Angle Class I malocclusion. The treatment results were achieved by mandibular molar intrusion using 1.8 × 8.

Tooth loss and craniofacial factors associated with changes in mandibular condylar morphology.

To investigate the association between tooth loss and craniofacial factors with changes in mandibular condylar morphology. A total of 123 patients participated in this cross-sectional study. The mandibular condylar morphology was evaluated using digital panoramic radiography.

Correction of Angle Class II division 1 malocclusion with a mandibular protraction appliances and multiloop edgewise archwire technique.

A Brazilian girl aged 14 years and 9 months presented with a chief complaint of protrusive teeth. She had a convex facial profile, extreme overjet, deep bite, lack of passive lip seal, acute nasolabial angle, and retrognathic mandible. Intraorally, she showed maxillary diastemas, slight mandibular incisor crowding, a small maxillary arch, 13-mm overjet, and 4-mm overbite.
