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)
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)
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)
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)
The aim of this preliminary study was to compare the initial bond strength of the glass-fiber-reinforced composite veil to the surface of the porcine calvarial compact bone using different adhesives. Fiber-reinforced composite (FRC) made of E-glass fiber veil with the BisGMA-PMMA resin system was used in the study. For the shear bond strength test, porcine(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)
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)
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 vivo model was developed to investigate the usability of a frontal sinus and a calvarial bone defect obliteration with bioactive glass S53P4 (BG) and hydroxyapatite (HA) granules. Roofs of 21 Elco rabbit frontal sinuses were drilled open from 4 separate holes using a standard method, and the sinuses, located in pairs, in frontal bone were filled with(More)
