CK Dental Industries’ Demineralized Cortical/Cancellous Granules is composed of ground iliac crest bone (60% cortical and 40% cancellous) that has been exposed to hydrochloric acid to remove the minerals exposing the BMPs (bone morphogenetic proteins). When mixed with mineralized cortical/cancellous granules, this osteoconductive product creates the most effective bone graft for regrowing bone.
