Introduction Rehabilitation of the edentulous alveolar ridge with dental implants is a common treatment modality. Successful esthetic and functional implant rehabilitation relies on sufficient bone volume in the vertical and horizontal dimensions, adequate bone contours, ideal implant positioning and angulation, periodontally healthy peri-implant soft tissue, adequate soft tissue contours, and ...

The Trichoptera fauna was sampled in a first order tributary of Paquequer River, in the district of Teresópolis, Rio de Janerio State. Quantitative samples of litter from pools, litter from riffles, sand, and stones were taken on each season from February 1991 to February 1992. The life cycles of common genera were categorized into three groups of biological strategies. The largest group repres...

The relaxation dynamics of the one-dimensional totally asymmetric simple exclusion process on a ring is considered in the case of step initial condition. Analyzing the time evolution of the local particle densities and currents by the Bethe ansatz method, we examine their full relaxation dynamics. As a result, we observe peculiar behaviors, such as the emergence of a ripple in the density profi...

Antibiotics have shown a proven efficiency profile in therapy against some infectious agents for several decades. Nevertheless, a large-scale spreading of antibiotics in the environment, and emergence of resistant or even multi-resistant pathogenic bacterial strains has become a general concern promise to even further increase. Besides therapeutic applications, antibiotics are often used as a s...

With an increase in the availability of implant restorative components, the selection of an appropriate implant abutment for a given clinical situation has become more challenging. This article describes a systematic protocol to help the practitioner more thoughtfully select abutments for single and multiple unit fixed implant prostheses. The article examines the evaluation, planning, design, a...

Until recently, angled abutments have been the only solution to correcting the trajectory of the emergence profile of labially inclined implants in the maxilla. However, the clinical implications of angled abutments reveal several shortcomings. Newly designed angulated implants with a 12-degree restorative platform angulation are an alternative to angled abutments. The purpose of this article w...

Migraine, a significantly disabling condition, is treated with acute and preventive medications. However, some individuals are refractory to standard treatments. Although there is a host of alternativemanagement options available, these are not always backed by strong evidence. In fact, most of the drugs used in migraine were initially designed for other purposes. Whilst effective, the benefits...
