Abstract
A bioresorbable and bioactive three-dimensional porous material made from bioresorbable polymers that can be combined with bioactive ceramics, producing a three-dimensional structure of interlinked pores containing additives capable of allowing the regeneration and formation of tissues, and a method for the production thereof is described.
Claims41
Bioresorbable and bioactive three-dimensional porous material characterized in that it comprises a base polymeric matrix comprised of combinations of polymers of natural or synthetic origin, that are selected from the group consisting of:
- lactide monomers and/or homopolymers in all the possible isomeric variants, such as D-lactide, L-lactide, DL-lactide;
- ε-caprolactone monomers and/or homopolymers;
- glicolyde monomers and/or homopolymers;
- polyesters and polyamides derived from aliphatic dicarboxylic acids and aliphatic hydroxyacids or aliphatic amino acids;
- poly(hydroxyalkanoate);
- poly(carprolactam);
- poly(trimethylene carbonate);
- poly(urethanes);
- as well as copolyesters, copolyamides and copolyester-amide derived therefrom, and/or mixtures thereof, wherein polymers are in monomeric ratios varying from 0.1% to 99.9% of the total composition of the base polymeric matrix.
