BACKGROUND Various instruments have been developed for collecting bone debris during intraoral autogenous bone graft procedures in implant surgery. The aim of this study was to quantitatively determine the degree of contamination in bone debris collected by different devices. METHODS Twelve patients underwent autogenous bone collection using a bone chisel, bone scraper, trephine drill, and bo...

Security of an encryption system is formally established through the properties of an abstract game played between a challenger and an adversary. During the game, the adversary will be provided with all information that he could obtain in an attack model so that the adversary is fully empowered to carry out the break. The information will be provided to the adversary through the answers of appr...

The Low-Energy Demonstration Accelerator (LEDA), designed and built at the Los Alamos National Laboratory, is part of the Accelerator Production of Tritium (APT) program and provides a platform for measuring high-power proton beam-halo formation. The technique used for measuring the beam halo employs nine combination Wire Scanner and Halo Scraper (WS/HS) devices. This paper will focus on the ex...

The osteogenic potential of autogenous bone grafts is superior to that of allografts and xenografts because of their ability to release osteoinductive growth factors and provide a natural osteoinductive surface for cell attachment and growth. There are different techniques for harvesting intraoral bone for augmentation, but new bone formation on the transplanted site with each of these methods ...
