    This chapter reveals that coating metallic-based implants with bioactive materials promotes joining between the prostheses and the bone, as well as increases long-term implant stability. The interface between different alloys and bioactive silicate glass coatings, prepared using a simple enameling technique, is analyzed at the nano level. Transmission electron microscopy and associated chemical analysis of the glass/alloy interface show the formation of thin Ti5Si3 or CrOx reaction layers. These nano structured interfaces facilitate the formation of a stable joint between the glass coating and the alloys. Nowadays, biomaterials such as Ti or Co-Cr alloys are widely used in orthopedic and dental implants. However, their long-term effectiveness needs improvement. In particular, metallic implants have a variety of shortcomings related to their affixation, and in many cases, failures are caused by poor adhesion of the implant to the tissue or bone. A commonly used strategy to improve osseointegration is to coat the alloys with a bioactive material that will accelerate the stabilization of the implant and extend its duration.
