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.

骨修复用磷酸钙X射线对比剂

摘要

得到了含有X射线造影剂（BiO）₂ CO _3的骨移植用磷酸钙复合水泥。它在水泥中的存在将使追踪骨组织再生的过程成为可能。由于水泥的多组分组成，其中某些相吸收较慢而另一些相迅速吸收，从而实现了成骨相关材料的长期供应。由于引入了聚乙二醇作为触变添加剂，因此可以通过内径为2 mm的注射器针头注射生成的水泥浆，而不会分层。
