bone tissue reactions to dental implants
there has been a lot of development in the science of implantology since forty years ago when extensive research began on this field of science. the use of dental implantology has also increased in the last decade, which the main reason is the success of it. recently some of our colleagues participate in short time introductory and advanced courses of implant inside or outside the country and b...
متن کاملTissue reactions of polypropylene mesh used in maxillofacial trauma.
Four 1-cm2 fragments of polypropylene mesh were implanted in the subcutaneous tissue of each of 10 albino rats to evaluate biocompatibility. A straight longitudinal incision was made on the back of these animals and histological analysis was carried out at 7, 15 and 30 days. At 7 days, there was a mild inflammatory reaction around the implanted material. On day 15, the inflammatory process cont...
متن کامل3D Wire mesh photonic crystals.
We have investigated the electromagnetic properties of a 3D wire mesh in a geometry resembling covalently bonded diamond. The frequency and wave vector dispersion show forbidden bands at those frequencies n0, corresponding to the lattice spacing, just as dielectric photonic crystals do. But they have a new forbidden band which commences at zero frequency and extends, in our geometry, to , 12 n0...
متن کاملAnisotropic geodesics for live-wire mesh segmentation
We present an interactive method for mesh segmentation that is inspired by the classical live-wire interaction for image segmentation. The core contribution of the work is the definition and computation of wires on surfaces that are likely to lie at segment boundaries. We define wires as geodesics in a new tensor-based anisotropic metric, which improves upon previous metrics in stability and fe...
متن کاملNormal and pathologic tissue reactions to soft tissue gel fillers.
BACKGROUND All gels act as foreign bodies. Host response ranges from a few macrophages to an intense foreign-body reaction with fibrosis, depending on gel type. For polymer gels the filling effect stems from their volume. For combination gels it stems from the intended host foreign-body reaction to the microparticles. OBJECTIVE This review explains how host tissue reacts with different gel ty...
