The purpose of this study is to demonstrate the effect of bioceramic implants on the repair of human bone defects, and to explore the application of bioceramic materials in bone defects, bone implantation, and bone fusion. The surface microstructure of β-tricalcium phosphate bioceramic implants can be effectively controlled to guide the regeneration of bones, promote the restoration of bones, accelerate the speed of recovery, and improve bone quality, which is of great clinical and social significance.
