AIM The reported effects of Bionator treatment in patients with mandibular retrognathism are conflicting. This study evaluated the changes in craniofacial morphology resulting from treatment with a Bionator, based on measurement percentiles previously reported, to clarify the mechanism of the effect of this commonly used functional device. MATERIALS AND METHODS Study Design: Retrospective. ...

Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlus...

PURPOSE This study was performed to evaluate the reproducibility of panoramic radiographs of dentulous and edentulous patients. MATERIALS AND METHODS The reproducibility of panoramic radiographs was evaluated using the panoramic radiographs acquired from 30 anterior dentulous patients by using a common biting positioning device (dentulous group) and 30 anterior edentulous patients by using ch...

D6050 Surgical placement: transosteal implant A transosteal (transosseous) bio-compatible device with threaded posts penetrating both the superior and inferior cortical bone plates of the mandibular sympysis and exiting through the perimucosa providing support and attachment for a dental prosthesis. Transcosteal implants are placed completely through the bone and into the oral cavity from extra...

We report about a novel imaging technique for airflow analysis, particle image velocimetry (PIV), used in a moderate obstructive sleep apnea (OSA) patient. By measuring the airflow characteristics in the upper airway at different protrusion positions, the effect of mandibular advancement device (MAD) on OSA was further understood.

The herbst mandibular advancement orthosis on thermoformed gutters is a recognized device for its effectiveness in reducing the apnea-hypopnea index. But its effect may be undermined by poor attendance on the part of the patient. This article poses this problem between the expected effects and those obtained by the healthcare team. It describes some practical solutions to solve them.
