Maxillary sinus floor augmentation with autogenous bone has become a widely accepted procedure in implant dentistry. The use of osteoconductive bone substitutes in this indication is controversial, since their use can lead to a prolonged healing time, inhomogenous ossification, foreign body reaction, migration of particles and low bone-implant contact(More)
In Germany, ∼ 13,000 people are found to have oral and pharyngeal cancer every year. Awareness and knowledge about this cancer remain insufficient, particularly amongst elderly people. A campaign for early detection was launched in Northern Germany in April 2012. The first step of the campaign was to increase awareness about oral cancer. Prior to a(More)
OBJECTIVE Treatment options for rheumatoid arthritis range from symptomatic approaches to modern molecular interventions such as inhibition of inflammatory mediators. Inhibition of inflammation by platelet-rich plasma (PRP) has been proposed as a treatment for tendinitis and osteoarthritis. The present study was undertaken to investigate the effect of PRP(More)
Orbital floor fractures, often combined with zygomatic fractures, are common fractures of the midface. Surgery of orbital fractures is done to free incarcerated or prolapsed orbital tissue and to restore the anatomic skeletal size of the orbit. Lyodura was a standard for the reconstruction of the orbital floor until cases of Creutzfeldt-Jakob disease were(More)
BACKGROUND It is controversial whether impaired well-being is associated with (a) an increased likelihood of having a negative body/facial image; or (b) dissatisfaction with the postoperative result following aesthetic surgery. We set out to improve current knowledge in this matter. METHODS A total of 324 subjects (n = 162 females, n = 162 males, 18-30(More)
The content of tumor necrosis factor (TNF)-alpha antigen and the bioactivity of soluble TNF receptor type II (sTNF-RII) in cerebrospinal fluid (CSF) from 29 patients with meningeal symptoms and fever were examined. Immunoreactive TNF was demonstrated in CSF from 4 of 7 patients with bacterial meningitis. In 3 of 8 patients with aseptic meningitis, CSF also(More)
INTRODUCTION Osteonecrosis of the jaw (ONJ) is an emerging condition in patients undergoing long-term administration of bisphosphonates (BP) for the treatment of osteoporosis and hypercalcaemia associated with malignancy, multiple myeloma, and metastatic breast and prostate cancers. This is a follow-up study, its purpose was to examine the effects in-vitro(More)
INTRODUCTION The purpose of this study was to examine whether the combination of an osteoinductive protein (recombinant human osteogenic protein-(rhOP-1 = bone morphogenetic protein-7) with natural bovine bone mineral (BioOss) would improve ossification and the bone-implant contact (BIC) in a sinus floor augmentation with simultaneous placement of implants.(More)
Two powerful architectures for interoperability, HLA and SOA (Service Oriented Architectures) have been developed during the past ten years. HLA has been developed within the defense simulation community. SOA has been developed within the commercial enterprise community. At first they may seem quite similar but a closer look reveals fundamental differences(More)
