Preparation of polylactide scaffolds for cancellous bone regeneration – preliminary investigation and optimization of the process

Polylactide scaffolds were prepared for the cancellous bone regeneration by the phase inversion method with freeze-extraction variant. A preliminary investigation and the optimization of the process were performed. For the obtained scaffolds, regression equations determining the effect: PLLA concentration by weight in 1,4-dioxane; volume ratio of the porophore/PLLA solution in 1,4-dioxane; and implant-forming solution pouring temperature, on the open porosity and mass absorbability were determined. The conditions in which the obtained implants were characterized by the maximal absorbability with the open porosity greater than 90 % were obtained.
