Fabrication of carbonate apatite honeycomb and its tissue response

Carbonate apatite (CO3 Ap) block can be used as a bone substitute because it can be remodeled to new natural bone in a manner conforming with the bone remodeling process. Among the many porous structures available, honeycomb (HC) structure is advantageous for rapid replacement of CO3 Ap to bone. In this study, the feasibility to fabricate a CO3 Ap HC was studied, along with its initial tissue response in rabbit femur bone defect. First, a...
