BACKGROUND Synthetic, osteoconductive, and antimicrobial bioactive glass (BAG) has been used in many surgical applications. METHODS BAG was used as obliteration material in a series of osteoplastic frontal sinus operations on 42 patients suffering from chronic frontal sinusitis, which could not be cured with other means of treatment. RESULTS Accurate(More)
UNLABELLED The aim of this study was to evaluate glass-fiber-reinforced composite as a bone reconstruction material in the critical size defects in rabbit calvarial bones. The bone defect healing process and inflammatory reactions were evaluated histologically at 4 and 12 weeks postoperatively. Possible neuropathological effects on brain tissue were(More)
PURPOSE Synthetic bioactive glass (BAG) is used in many surgical applications. Special bioactive glasses do not favor microbial growth. This study evaluated the clinical outcome of bioactive glass plates in reconstructive orbital surgery. PATIENTS AND METHODS In a retrospective series of 49 patients, 35 orbital floors and 6 orbital medial and superior(More)
OBJECTIVE The aim of this preliminary study was to test the bioactive glass-coated fiber-reinforced composite (FRC) as a reconstruction material in the treatment of experimental defects in the frontal bone of rabbits. METHODS FRC made of E-glass fiber and BisGMA-PMMA resin matrix system was used in the study. Pieces of nonpolymerized FRC were coated with(More)
The aim of this study was to characterize the microstructure and mechanical properties of porous fiber-reinforced composites (FRC). Implants made of the FRC structures are intended for cranial applications. The FRC specimens were prepared by impregnating E-glass fiber sheet with non-resorbable bifunctional bis-phenyl glycidyl dimethacrylate and triethylene(More)
BACKGROUND Bioactive glass (BG) is a glass ceramic material. It has been used as surgical bone replacement material in ear and oral surgery, orthopedics, and dentistry. METHODS Bioactive glass was used as obliteration material in a series of osteoplastic frontal sinus operations on 10 patients suffering from chronic frontal sinusitis, which other,(More)
Three synthetic bioactive materials were studied in an experimental model to compare their usability in a frontal sinus and a skull bone defect obliteration. Bioactive glass number 9 (BAG(1)), bioactive glass number 13 (BAG(2)), and hydroxyapatite (HA) granules were investigated. BAG(1) and HA granules have been previously tested clinically. The clinical(More)
BACKGROUND Synthetic bioactive ceramics and glasses have osteoconductive properties. These materials are capable of chemically bonding to the bone tissue. In addition, special bioactive glasses do not favor microbial growth. In this study, the clinical outcome of bioactive glass and hydroxyapatite in head and neck surgery was evaluated. METHODS In a(More)
Bioactive glass S53P4 (BG) is an osteoconductive allograft material. Since 1990, BG has been used in the obliteration of frontal sinuses in more than 30 consecutive patients. The patients have been monitored regularly with clinical examinations, computer tomography (CT) scans, laboratory tests and, in a few cases, biopsies have also been obtained. The(More)
An in vitro model was used to investigate the behavior of a massive frontal sinus obliteration with bioactive glass S53P4 (BG) for clinical purposes. Two sizes of granules (0.63-0.8 mm or 0.8-1.0 mm) in 16 separate BG amounts, weight 25 g, were tested both in simulated body fluid (SBF) and a buffer containing trishydroxymethyl aminomethane citric acid(More)
