The present invention relates to a coating, a substrate, a method for coating a body and a method for producing the body substrate, such as a dental or a bone an implant.The coating has a high degree of hardness and comprises elements, such as Sr based compounds, which optimize the tissue response to the implanted body thus stimulating healing, bone or tissue growth in the vicinity of the implant.An implant coated with this coating has the ability of sustained release of strontium in a non-toxic concentration of strontium in the vicinity of the implant.
