Abstract: An injectable heat generating biocompatible ceramic compositions based on hydraulic calcium aluminate, which can be used for therapeutic treatment in vivo, such as tumour treatment, pain control, vascular treatment, drug activation etc, when curing in situ, and which form a biocompatible solid material that can be left in the body for prolonged periods of time without causing negative health effects, and can also be used to restore the mechanical properties of the skeleton after cancerous diseases as well as in a medical implant, an orthopaedic implant, and a dental implant as a dental filling material.

Abstract: The present invention generally relates to dental and orthopaedic implants, and more specifically to an implant coated with a chemically bonded ceramic, having a modified substrate surface to improve adhesion of the implant coating to the implant material, wherein the coating includes a gradient zone also containing the material of the implant device wherein the concentration of the implant device material decreases in a direction towards the surface of the coating, and a method of preparing the coated implant as a method of implanting the implant device.

Abstract: Implant device having a coating of a chemically bonded ceramic material exhibiting improved adhesion of the coating to the surface, wherein the surface of the implant underlying the coating exhibits a surface structure containing cavities having a width “a”, a depth “c”, and a distance between neighbouring cavities “b”, wherein 80<a<200; 50<b<400; and 20<c<200 ?m, and method for preparing the implant.
