Abstract:
Bone defects, often accompanied by osteomyelitis, soft tissue contusions, etc, are facing lengthy treatment process and slow healing, seriously jeopardizing the structural integrity of the human bone tissue. Currently, the main treatment for bone defects involves autologous or allogeneic bone transplant. However, autologous bone transplant poses problems, including long surgical duration, increased pain and complications such as infections. Additionally, immune rejection reactions also limit the effectiveness of allogeneic bone transplant of the same species. Bone scaffolds have become a potential alternative for bone transplant, but problems such as sharp edges of the scaffolds and poor compatibility with human tissues exist. Triply periodic minimal surface (TPMS), with an average curvature of zero has lower levels of stress concentration and the ability to be precisely expressed with mathematical formulas, compared with other structures. Its application in bone scaffolds attracts much attention, but there is currently a lack of comprehensive understanding of the impacts of different types of TPMS on the performance of bone scaffolds. With this purpose, the authors reviewed the research progress in the impacts of different types of TPMS on the performance of bone scaffolds, providing a reference for the construction of bone scaffolds.
