ABSTRACT
Bioceramics are ceramic materials that have been specially developed for repairing hurt or damaged hard tissues, such as bone and teeth. Most of the existing bioceramics are biocompatible, and some of them are bioactive with good bone bonding capability and have been applied successfully in the clinic. The study of bioactive silicate ceramics for bone tissue regeneration has become a hot topic. The research has focused on the ceramic preparation methods, mechanical strength, apatite mineralization, dissolution, bioactive properties and corresponding mechanism. The sintering process is necessary for the fabrication of bioceramics with certain mechanical properties and structures. The development of regenerative engineering provides an effective approach for tissue repair and regeneration. The selection of scaffold material and structure optimization is important to fully mimic the 3D network structure of natural tissue. Bioactive ceramics and metals are drawing more attention due to their excellent biocompatibility and osteogenesis.
