Biological Evaluation of Bioceramic Materials - A Review

The uses of bioceramics have been revolutionizing the biomedical field in deployment as implants for humans. Many implant materials made of ceramics have been used for the past three decades. In the search to improve the biocompatibility and mechanical strength of implant materials, attention has been directed towards the potential use of ceramic/ceramic composites. The ceramic-based biomaterials have been accepted after biological evaluation through several in vivo and in vitro tests. In this review an attempt has been made to elicit some of the in vivo and in vitro studies performed on bioceramics, ceramic/ceramic composites and their applications as implants.
