Abstract

Injectable pastes are bioactive materials which are used in various forms in the living organism. The bioactivity of these materials are derived from calcium phosphate powder and/or a bio-glass composition. These materials are not individually injectable; however, they will be when suitable polymers such as chitosan, gelatin, sodium alginate, hyaluronic acid, etc. added to the paste. In this research, the authors have tried to prepare a bioactive injectable glass/polymer paste via mixing a sol-gel derived glass powder, based on the SiO2-CaO-P2O5 system, with polymer’ s solution of gelatin. The rheological behavior and the injectability of the pastes were also investigated. The results showed that the paste was well-injected; however, it showed an undefined rheological behavior. The maximum viscosity of the paste was 8. 88 × 10 Pa. s and it was washed out during it’ s immersion in a simulated body fluid with time and reached to approximately 60wt. % of its initial weight after 48h. According to microstructural analysis, mineralogical phase analysis and Fourier Transform IR spectrometry analysis, the paste showed bioactivity after 14 days immersion in SBF solution.
