Biomedical and Dental Materials

Biomedical and dental materials are substances engineered for use in medical devices, implants, dental restorations, and other healthcare applications. Their design balances function, durability, and interactions with the body.

Biocompatibility: The ability of a material to perform with an appropriate biological response in a specific application. It frames how a material’s contact with tissue or fluids is evaluated.
Orthopedic implant: A device implanted to replace, support, or stabilize a bone or joint. Its load-bearing function demands wear resistance, strength, and tissue compatibility.
Osseointegration: The direct structural and functional connection between living bone and the surface of a load-bearing implant. It is a key biological outcome for many dental and orthopedic implants.
Titanium: A lightweight, corrosion-resistant metal used in alloys and in some medical and dental implants. It is a common metallic implant choice, unlike brittle ceramic alternatives.
Degradation of biomaterials: The chemical, physical, or biological breakdown of materials during use in or around the body. Predicting degradation helps determine implant lifetime and the consequences of released products.
Biomaterials: Materials designed to interact with biological systems for medical or biological purposes. This broader field includes materials for implants, devices, and tissue repair.
Dental amalgam: A restorative dental material made by combining liquid mercury with an alloy powder, usually containing silver, tin, and copper. It illustrates a durable restorative material with distinctive handling and safety considerations.
Protein adsorption: The accumulation of proteins from a fluid onto a material’s surface. Adsorbed proteins shape subsequent cell attachment and immune responses.
Cobalt-chromium alloy: A family of cobalt-based alloys valued for strength, corrosion resistance, and wear resistance. It offers a hard, wear-resistant alternative to titanium in selected implant applications.
Nanotoxicology: The study of harmful effects that engineered or incidental nanoscale materials may have on organisms. Nanostructured surfaces and particles raise questions about exposure, persistence, and tissue effects.
