ABSTRACT:
The invention relates to a heterophasic composition which essentially consists of three immniscible components, A, B and C, and the production method of the same. The component A is some body compatible polymer, the component H is a water soluble or hydrolytically degradable substance which produces cavities or network like porosity after disappearing through solubilization or degradation, and a bioactive substance C which at least component B contains in form of particles as a blend component and which still exists in the pores or their walls after the degradation or solubilization of the component B. The materials according to the invention are biocompatible, solid in normal temperatures, mechanically processable, and thermally mouldable as well as bioactive in the sense that they have the capability to renew different kinds of tissues in the body, on the surface of the living organisms, in the cavities of the body and in the tissue engineering conditions outside the body, and that they can be used in tissue engineering, in tissue regeneration, in healing of damaged or lacking tissues, in tissue guiding when treating deficiencies, in controlled drug release, in the treatment methods of dentistry, in orthopedics and in plastic surgery.
