Ceramic-metallic composites are a new family of biodegradable, load-bearing and cytocompatible materials. The composites may range from ceramic matrix to metallic matrix materials, processed either by current assisted sintering, current assisted metal infiltration, or infiltration of self-setting ceramics into additively manufactured metallic skeletons. The mechanical behaviour of the composites can be tailored through the ceramic to metallic ratio and by the computer aided design of the topological relationship, enabling the production of composites with elastic module in the range of bone and mechanical strength similar to the strength of stiffer implantable metals. By selecting the proper metallic phase the composites may show fast or slow degradation rate, allowing the personalized treatment of patients. The composites avoid implant removal after bone healing, being promising candidates for the treatment of young patients. Last but not least, the use of calcium phosphates as ceramic phase result in osteoconductive and bioactive composites.
