Understanding the relationship between pore structure and properties of triply periodic minimal surface bone scaffolds

Abstract

The number of patients with bone defects caused by trauma and diseases has been increasing year by year. The treatment of bone defects remains a major challenge in clinical practice. Bone scaffolds are increasingly favored for repairing bones, with triply periodic minimal surface (TPMS) scaffolds emerging as a popular option due to their superior performance. The aim of this review is to highlight the crucial influence of pore structure on the properties of TPMS bone scaffolds, offering important insights for their innovation and production. It briefly examines various elements that influence the properties of TPMS bone scaffolds, such as pore shape, porosity, pore diameter, and curvature. By analyzing these elements, this review serves as a valuable reference for upcoming research and practical implementations in the field of bone tissue engineering.
