EN The main objective of the work was to design and fabricate an injectable biomaterial with osteoconductive properties that can be used in dental applications in peri-implant therapy concerning guided bone regeneration. For that purpose, a self-setting biomaterial consisting of chitosan/tricalcium phosphate microparticles and sodium alginate was formulated. The obtained material was characterized regarding microsphere and formed agglomerates morphology and microstructure. Physical properties, relating to setting time and mechanical properties, were also investigated. Finally, in vivo response to implanted biomaterial was studied on a rat model and compared with commercially available alloplastic material. The results showed that designed injectable biomaterial fulfi lled main requirements for guided bone regeneration application.
