Digitally Augmented Learning in Implant Dentistry.

The economic forces in the dental education industry yield a high cost for a dental degree, yet the financial return for this education yields a small margin above the costs for this degree. Industries with unfavorable return to investment ratios tend to be vulnerable to changes. Productive technologies are emerging that may be useful in improving the return to investment ratios in dental education.

An intra-bone axial load transducer: development and validation in an in-vitro radius model.

Background: Accurate measurement of forces through the proximal radius can assess the effects of some surgical procedures on radioulnar load sharing, but is difficult to achieve given the redundant loading nature of the musculoskeletal system. Previously reported devices have relied on indirect measurements that may alter articular joint location and function. An axial load transducer interposed in the diaphysis of the radius may accurately quantify unknown axial loads of the proximal radius, and maintain articular location.

The effect of fracture comminution on the reliability and accuracy of radial head sizing.

Background: Radial head implant sizing can be based on the maximum head diameter (D-MAX), the minimum head diameter (D-MIN), or the articular dish diameter (D-DISH). The purpose of this study was to assess the reliability of the different radial head sizing techniques and to investigate the effect of radial head fracture comminution on measurement accuracy.

Methods: Ten observers measured 11 cadaveric radial heads with 3 radial head features (D-MAX, D-MIN, and D-DISH diameter).

Indomethacin reduces cell damage: shedding new light on compartment syndrome.

Introduction: Indomethacin may preserve tissue viability in compartment syndrome. The mechanism of improved tissue viability is unclear, but the anti-inflammatory effects may alter the relative contribution of tissue necrosis versus apoptosis to cellular injury. Existing studies have only considered indomethacin administration before induction of elevated intracompartment pressure.

Temporal bone fractures: a review for the oral and maxillofacial surgeon.

Fracture of the temporal bone is, by definition, a fracture of the skull base. Even though the oral and maxillofacial surgeon (OMS) may not provide definitive management of temporal bone fractures or their sequelae, a working knowledge of this area is important for any surgeon participating in the care of patients with craniomaxillofacial trauma, because temporal bone fractures are often associated with injuries to other areas of the craniomaxillofacial skeleton and because these fractures are relatively frequent. In many centers, particularly community hospitals, the OMS may be the primary provider of care for facial trauma and will treat patients with clinical or radiographic evidence of temporal bone fractures.
