The biomaterials sector has been rapidly expanding and significant advances have been made in the technology of biomedical coatings and materials. Approximately 44% of all medical devices are based on fixation devices and artificial joints. However, limitations are associated with biomedical implants such as infections, osseointegration, degradation, and wear. The coating on biomedical implants can provide a means to improve the wear of joints, change the biological interaction between implant and host, and combine the properties of various materials to improve device performance. Currently, several techniques of coating on biomedical implants have been developed such as electrodeposition, plasma spray, sol-gel, micro-arc oxidation, anodization, plasma electrolytic oxidation, magnetron sputtering, and pulsed laser deposition, etc.

Metallic implants are still the biomaterial of choice for numerous clinical applications such as dental, orthopedic, and cardiac implants due to their mechanical properties. However, there are several inherent problems associated with these implants, such as wear, corrosion, biocompatibility, and toxicity, which must be addressed before implantation in a biological environment. Modifying these metal surfaces by applying special coatings can improve their performance safety. The goal of this Research Topic is to first cover the fundamentals of metals as a biomaterial and then explore surface coating and modification techniques of metallic and non-metallic biomaterials.

The Research Topic collection will cover the coatings on surfaces that come in contact with the human body. The topics of interest include, but not limited, the following:
- Processing of coatings on dental implants
- Surface modifications of metallic and non-metallic biomedical and dental implants
- Biocompatible and antimicrobial surface coatings
- Biological, Inorganic, and Polymer coatings
- Bioceramics coatings
- Coatings of growth factors, proteins, and peptides
- In vitro and in vivo analysis of coated implants
