Characterization of implants. (A) XRD patterns of drug-loaded resin with CRO content of 1%, 5%, 10% and CRO (100%). (B) SEM image of 3D printed implants: (a) and (b) were the vertical section view, (c) and (d) were the cross section view. (C) In vitro cytotoxicity of the leachate from the implanted scaffold. n = 3, **, p < 0.01; ****, p < 0.0001.
