The challenges and demands of implant materials are changing as a result of the substantial expansion in the global population. Suitable implants are required for aged people, physical injuries, patients who need revised surgeries, contaminated implants, and accident victims. Hence, the requirement for implants is drastically increasing day by day. Metals, ceramics, and polymers are used as implant materials by biomedical industries for long-term suffering patients. Stainless steel, titanium and its alloys, aluminum alloys, cobalt, zirconium, etc. (metals), hydroxyapatite (ceramic), polyurethane, polyethylene, polyimide, etc. (polymers), are some of the examples that fulfill the implant requirements. There are many other obstructions, such as adhesion, inflammation, and bacterial attack, which minimize the implant’s performance and its activity. However, coatings on ideal implant materials are significant to avoid its failure and to enhance its durability and longevity. Advanced techniques, such as physical and chemical methods, are suitable coating approaches to promote the surface of implants with respect to mechanical, biological, and other multifunctional activities. This review paper focuses on and investigates several strategies for bioactive implants’ coatings, analysis, and emerging applications for biomedical industries.
