OBJECTIVE To present the results from using biological ceramics for filling bone defects resulting from post-traumatic or orthopedic injuries. METHODS Thirty-six patients with bone defects caused by trauma or orthopedic injury were evaluated. Nineteen patients were male (52.8%) and 17 were female (47.2%). Their ages ranged from 19 to 84 years, with a mean of 45.7 years and median of 37 years....

This review focuses on bone substitute composites made by mixing ceramic biomaterials with fibrin sealants. Different biomaterials such as coral, bone-derived materials, bioactive glass ceramics, and synthetic calcium phosphate have been mixed with fibrin sealant, resulting in a combination of the biological properties of the two components. This type of association has not produced identical r...

The present study describes the influence of potassium and hydroxyl substitutions on structural, thermal mechanical properties fluorapatite bioceramics. A set non-stoichiometric ion-substituted compounds, with a chemical formula Ca10−xKx(PO4)6F(2−2x)(OH)x 0 ≤ x 1 synthesized by wet precipitation method, were found to be single-phase apatites crystallizing in hexagonal P63/m space group. structu...

This paper studies the AC conductivity and permittivity of hydroxyapatite (HA)-based ceramics from 0.1 Hz-1 MHz at temperatures from room temperature to 1000 degrees C. HA-based ceramics were prepared either as dense ceramics or in porous form with interconnected porosity and were sintered in either air or water vapour. Samples were thermally cycled to examine the influence of water desorption ...

The capacity to induce rapid vascular ingrowth during new bone formation is an important feature of biomaterials that are to be used for bone regeneration. Akermanite, a Ca-, Mg- and Si-containing bioceramic, has been demonstrated to be osteoinductive and to promote bone repair. This study further demonstrates the ability of akermanite to promote angiogenesis and investigates the mechanism of t...
