About the Mechanical Strength of Calcium Phosphate Cement Scaffolds

For the treatment of bone defects, biodegradable, compressive biomaterials are needed as replacements that degrade regenerates. The problem with existing materials has either been their insufficient mechanical strength or excessive differences in elastic modulus, leading to stress shielding and eventual failure. In this study, CPC ceramics (with a layer thickness more than 12 layers) was compared sintered β-TCP ceramics. It assumed number layers increased, 3D-printed scaffolds would increase toward value addition, influence needle inner diameter on investigated. Circular 20, 25, 30, 45 were 3D printed using bioplotter, solidified water-saturated atmosphere for 3 days, then tested together ceramic Zwick universal testing machine. had 41.56 ± 7.12 MPa, which significantly higher (24.16 4.44 MPa). round geometry reached exceeded upper limit cancellous substantia compacta. exhibited bone-like compressibility comparable ceramic, demonstrating properties similar
