3 results about "Biodegradable scaffold" patented technology

This invention relates to the development of a biodegradable scaffold containing growth factor and antibiotic loaded nanoparticulate systems with the aim of enabling the regeneration of the pulp-dentin complex of immature permanent teeth with necrotic pulp damaged due to infection, trauma, or developmental anomalies.

This invention belongs to the field of bone replacement material technology, specifically relating to a porous biodegradable bone replacement scaffold and its preparation method. The porous biodegradable scaffold of this invention consists of pillars, each pillar having an outer shell and a core. The outer shell comprises ZnO, and the core comprises Zn. The porous biodegradable bone replacement scaffold of this invention has a nano- to millimeter-level hierarchical pore structure, which is more similar to the structure of human bone. Furthermore, its degradation performance, antibacterial properties, and biocompatibility are superior to existing biodegradable metallic bone implant materials (zinc and its alloys), which helps promote osteogenic differentiation.
