As previously mentioned, polymer is designed to degrade at the rate gradually transferring mechanical support from itself to the new forming bone tissues. Eventually, the polymer starts degrading and create space of infiltrating cells such as osteoblasts, mesenchymal stem cells, and endothelial cells, which are essential for bone formation and vascularization. So, the polymer is designed to resorb in the body after the regeneration of bone by natural metabolic processes .
