Currently, a variety of substances such as composites, synthetic ceramics, corals, polymers, and metals can be utilized for the replacement or repair of bones and teeth. Nano-bioceramics are frequently used as coatings on metal implants to improve their bioactivity, functionality, and resistance to wear and corrosion. The development and progress of nano-bioceramics using novel techniques has garnered considerable attention due to their unique characteristics, which are contingent upon their dimensions and configuration. By altering the morphology and dimensions of nano-bioceramics, as well as including additional elements as impurities or inducing defects by ion implantation, it is possible to induce modifications in their biological, chemical, and physical characteristics. Extensive research has been conducted on the ability of hydroxyapatite to accelerate the regeneration of rigid tissues. However, tricalcium phosphate is a preferable biomaterial compared to HA because it has superior osteoconductivity, improved biodegradability, increased biocompatibility, and enhanced solubility. Recent studies indicate that bioactive ceramics with magnesium can greatly enhance the attachment of bone cells and promote rapid proliferation and multiplication of osteoblasts. Silicate biomaterials, such as bioglasses and silicate bioceramics, have the ability to release ions that stimulate the growth of blood vessels (angiogenesis), the proliferation of fibroblastic cells, and exhibit antimicrobial properties. These actions are essential for the process of tissue repair and regeneration. The utilization of 3D printing is a cutting-edge approach for fabricating implants and bone ceramic materials. Various techniques exist for the 3D printing of ceramics, each with its own set of benefits and drawbacks. By utilizing these techniques, it is possible to fabricate porous scaffolds with precise dimensions and forms, making them suitable for treating fractures and abnormalities of bone. Nanotechnology has significantly enhanced the development of ceramic materials with distinct biological characteristics. This chapter will provide a comprehensive overview of nano-bioceramics, with a specific focus on their 3D printing capabilities and the significant role played by nanotechnology.
