What is a biomaterial?
A biomaterial is any substance that has been engineered to interact with biological systems for a medical purpose, either for a therapeutic (treat, augment, repair, or replace) a tissue function.
Define bioactivity in the context of biomaterials.
Define bioactivity in the context of biomaterials.
Bioactivity refers to the ability of an engineered biomaterial to induce a physiological response that is supportive of the biomaterial's function and performance.
Explain the concept of biocompatibility in relation to medical devices or materials.
Explain the concept of biocompatibility in relation to medical devices or materials.
Biocompatibility is the ability of a medical device or material to perform with an appropriate host response in a specific application. It is a measurement of how compatible a device or material is with a biological system.

Study Notes
Biomaterials and Bioactivity
- Biomaterial is any substance engineered to interact with biological systems for a medical purpose, including treating, augmenting, repairing, or replacing tissue function.
Bioactivity
- Bioactivity refers to the ability of an engineered biomaterial to induce a physiological response that supports the biomaterial's function and performance.
- It involves the ability of implanted materials to bond well with surrounding tissue in either osseoconductive or osseoproductive roles.
Biocompatibility
- Biocompatibility is the ability of a medical device or material to perform with an appropriate host response in a specific application.
- It is a measurement of how compatible a device or material is with a biological system.
- Biocompatibility is not an intrinsic property of any material, but rather the characteristic of the 'implant-organism' system corresponding to their condition-specific contact.
- ISO 10993-1 provides guidelines for the biological evaluation of medical devices.
