This term means that an object or material has an effect on or elicits a response from living tissue. In dental applications, bioactive materials are essential as implants, prostheses, and other structures must properly interact with the teeth, gums, tongue, and other tissues of the mouth. Metal oxides are frequently used to create bioactive dental structures since they have the ability to form chemical bonds with living tissues. These bonds build a stable scaffold upon which new cells can grow in preparation for an implant procedure or as part of the healing process. Bioactive materials are essential in medical and dental procedures as they help reduce the risk of infection or rejection in the affected tissues as well as in the tissues surrounding the procedure site. The specific bioactive material used can depend upon the type of procedure, the dental structure needed, and even the preference of the dental professional.
