Background and Objective: The concept of immediate occlusal loading with dental implants offers several advantages. In this research, the effect of type of restoration on Osseointegration rate of dental implants was histologically evaluated. Materials and Methods: Three months prior to implantation, the lower premolar teeth of 15 dogs were extracted. Then, 3 to 4 Maestro™ implants were plac...
Four uncemented Symax hip stems were extracted at three weeks and nine, 13 and 32 months, respectively, for reasons other than loosening. The reasons for implant removal were infection in two cases, recurrent dislocation in one and acetabular fracture in one. They were analysed to assess the effect and behaviour of an electrochemically deposited, completely resorbable biomimetic BONIT-hydroxyap...
BACKGROUND Transfusion-dependency affects the natural history of myelodysplastic syndromes. Secondary iron overload may concur to this effect. The relative impact of these factors on the outcome of patients with myelodysplastic syndrome receiving allogeneic stem-cell transplantation remains to be clarified. DESIGN AND METHODS We retrospectively evaluated the prognostic effect of transfusion h...
The effects of process parameters on the extraction of Ginkgo biloba L. leaves with supercritical carbon dioxide were investigated. The investigated parameters include particle size (mean particle diameter 0.19, 0.467 and 1.009 mm), solvent flow rate (1.58×10, 3.22×10 and 4.16×10 kg CO2/min) and pressure (100–300 bar), which were obtained by the response surface methodology (RSM) under the foll...
OBJECTIVE Dental implants anchor in bone through a tight fit and osseo-integratable properties of the implant surfaces, while a protective soft tissue seal around the implants neck is needed to prevent bacterial destruction of the bone-implant interface. This tissue seal needs to form in the unsterile, oral environment. We aim to identify surface properties of dental implant materials (titanium...
