Despite possessing impressive qualities and the ability to imitate bone properties, the exclusive use of ceramic materials still encounters significant limitations. By combining ceramic materials with other biological materials, it is possible to mitigate their drawbacks and introduce novel and distinctive characteristics. The qualities of biological materials utilized for bone can be altered in a flexible and unrestricted manner. Furthermore, the enhancement of the biological characteristics of ceramics can be achieved by including various biological components. These materials can be fabricated as a composite consisting of ceramic-polymer, ceramic-hydrogel, and even ceramic-ceramic nanocomposites. Polymers have great promise for being used with bioceramics. Biodegradable polymers are utilized in several fields such as tissue engineering, medication delivery, cardiovascular applications, dental applications, orthopedic devices, and wound treatment. They can be classified into two distinct categories including natural polymers and synthetic polymers. Significant drawbacks of natural polymers are their quick breakdown rates and subpar mechanical properties. Various synthetic polymers have undergone substantial research for a wide range of biomedical applications due to their advantageous properties of being able to degrade naturally and being compatible with living organisms. Each polymer possesses unique features and characteristics, which will be thoroughly discussed in this chapter. Then, we will review the various combinations of diverse materials with commonly used nano-bioceramics.
