dc.description.abstractComposites membranes of poly(lactic acid)/poly(ethylene glycol)/hydroxyapatite (PLLA/PEG/HA), presenting uniform porosity distribution and characteristics appropriate for guided bone regeneration (GBR), were prepared in this work. The appropriate combination among polymer components (PLLA:PEG-1000, 2:3) and a biocompatible reinforcing ceramic filler (HA, 20 wt%), resulted in the development of composite devices presenting new mechanical and biological characteristics, ideal for bone matrix substitution, which allows cell growth. The membranes were prepared with a uniform porous (4 m) structure suitable for cells penetration, anchorage, differentiation and proliferation. The homogeneous porosity in membranes was achieved by self-organization during solvent evaporation process, due to phase-separated structure of the composites. The in vitro culture of osteoblasts on PLLA/PEG/HA membranes indicated good biocompatibility.
