The purpose of this study was to develop an improved technique of alveolar ridge augmentation by distraction osteogenesis using distraction screws, and to investigate tissue reactions to titanium implants at the distraction site. The left mandibular premolars were extracted from 6 adult dogs. After 12 weeks, a box-shaped osteotomy of the alveolar bone was carried out, and distraction devices we...

Majority of surgical experience with distraction technology has been in orthopaedics. Early results indicate the process to be equally effective in facial skeletal reconstruction. Distraction osteogenesis has proven to be a major advance for the treatment of several congenital and acquired mandibular deformities. A review of the literature dealing with distraction osteogenesis (DO) of the mandi...

Auditory distraction is a failure to maintain focus on a stream of sounds. We investigated the neural correlates of distraction in a selective-listening pitch-discrimination task with high (competing speech) or low (white noise) distraction. High-distraction impaired performance and reduced the N1 peak of the auditory Event-Related Potential evoked by probe tones. In a series of simulations, we...

Congenital brachymetatarsia most commonly involves the fourth ray and may be combined with metacarpal shortening. Now, many reports demonstrated the usefulness of distraction osteogenesis for lengthening of the metatarsals by using an external distraction device. In this article, we treated shortening fourth metatarsal by bone lengthening using the internal distraction device. This technique ha...

In a recent study, we observed that saccadic distraction (i.e., the remote distractor effect, RDE) was reduced when target and distractor were displayed at unequal contrast [Born, S., & Kerzel, D. (2008). Influence of target and distractor contrast on the remote distractor effect. Vision Research, 48(28), 2805-2816]. We hypothesized that arrival times explain the RDE modulation: With equal cont...

Distraction osteogenesis is a process that depends on biomechanics, where the application of progressive traction forces leads to bone lengthening by gradual new bone formation. (Illizarov, 1989a, 1989b) Consequently, stretching of surrounding soft tissues occurs at different tissue depths, allowing correction of severe skeletal dysplasias in short periods of time. However, biomechanical data f...

Study design: Retrospective case review. Introduction: Ischemic insults from blunt cerebrovascular injuries (BCVI) can lead to significant cranial and spinal injury. Specific spine fracture patterns have been identified as more predictive of BCVI, such as vertebral subluxation, fractures through the foramen transversarium, and C1 through C3 fractures. Adequate screening and early treatment has ...

OBJECTIVE To test whether a head-mounted display helmet enhances the effectiveness of videogame distraction for children experiencing cold pressor pain. METHOD Forty-one children, aged 6-14 years, underwent one or two baseline cold pressor trials followed by two distraction trials in which they played the same videogame with and without the helmet in counterbalanced order. Pain threshold (ela...

This study examined the effect of background music upon performance of creative and non-creative individuals on a reading comprehension task. In the presence of musical distraction and silence, 54 individuals (27 creative) carried out reading comprehension tasks in a repeated measures design. An interaction was predicted, such that musical distraction would have a greater negative effect on the...

Attending to emotional stimuli is often beneficial, because they provide important social and environmental cues. Sometimes, however, current goals require that we ignore them. To what extent can we control emotional distraction? Here we show that the ability to ignore emotional distractions depends on the type of cognitive control that is engaged. Participants completed a simple perceptual tas...
