An original definition of bioactivity is:

“Bioactivity refers to the ability of a material to elicit a specific reaction at its surface when implanted in the body, leading to the formation of a strong bond at its interface with bone or soft tissue.”

The calcium phosphate ceramic hydroxyapatite and certain compositions of glasses, referred to as bioactive glasses, satisfy this definition (Chapter 7). If the requirement of forming a strong bond with bone and soft tissues is omitted, the definition becomes broader. The term is now used more commonly in this broader sense.
