Abstract

Calcium phosphate composite cements for bone grafting containing an X-ray contrast agent, (BiO)2CO3, were obtained. Its presence in cement will make it possible to track the process of bone-tissue regeneration. Due to the multicomponent composition of the cement, in which some of the phases are resorbed slowly and others quickly, a prolonged supply of the material involved in osteogenesis is achieved. The resulting cement paste can be injected through the needle of a syringe with an internal diameter of 2 mm, without delamination, due to the introduction of polyethylene glycol as a thixotropic additive.
