Determination of bioceramic filler distribution and porosity of self-reinforced bioabsorbable composites using micro-computed tomography
Autor: Minna Kellomäki, Dogu Baran Aydogan, Jari Hyttinen, Markus Hannula, Tiiu Niemelä
Publikováno v: Composites Part A: Applied Science and Manufacturing. 42:534-542
A micro-computed tomography (μ-CT) image analysis was used in the micro-structural analysis of self-reinforced bioabsorbable osteoconductive composites. The composites studied were known to have a porous structure, but the total porosity of these co

Manufacturing, mechanical characterization, andin vitro performance of bioactive glass 13–93 fibers
Autor: Pertti Törmälä, M. Brink, Eija Pirhonen, Tiiu Niemelä, Henna Niiranen
Publikováno v: Journal of Biomedical Materials Research Part B: Applied Biomaterials. :227-233
Fibers were manufactured from the bioactive glass 13–93 by melt spinning. The fibers were further characterized by measuring their tensile and flexural strength, and their in vitro performance was characterized by immersing them in simulated body f

Self-reinforced composites of bioabsorbable polymer and bioactive glass with different bioactive glass contents. Part I: Initial mechanical properties and bioactivity
Autor: Tiiu Niemelä, Minna Kellomäki, Pertti Törmälä, Henna Niiranen
Publikováno v: Acta Biomaterialia. 1:235-242
Spherical bioactive glass 13-93 particles, with a particle size distribution of 50-125 microm, were combined with bioabsorbable poly-L,DL-lactide 70/30 using twin-screw extrusion. The composite rods containing 0, 20, 30, 40 and 50 wt% of bioactive gl

Self-reinforced composites of bioabsorbable polymer and bioactive glass with different bioactive glass contents. Part II: In vitro degradation
Autor: Tiiu Niemelä, Henna Niiranen, Minna Kellomäki
Publikováno v: Acta biomaterialia. 4(1)
The in vitro degradation behavior of self-reinforced bioactive glass-containing composites was investigated comparatively with plain self-reinforced matrix polymer. The materials used were spherical bioactive glass 13-93 particles, with a particle si

Bioactive glass and biodegradable polymer composites
Autor: Minna Kellomäki, Tiiu Niemelä
Publikováno v: Tampere University
Bioactive ceramic materials have osteoconductive potential and excellent bone-bonding character, but they do not fulfill the required mechanical properties to replace bone tissue. Polymeric biomaterials have in many cases more applicable mechanical p
