In order to reduce long term infection risks‚ it is necessary for the scaffold to maintain a silver ion release for the length of the healing process. In this study‚ silver doped porous β-tricalcium phosphate (β-TCP) scaffolds were engineered using liquid porogen based method with the goal of meeting these requirements. Silver was added to the β-TCP at
