Abstract of US2004241613

The invention relates to a method for depositing a coating onto an implant for implantation in bone. In this method a coating is deposited by the ESD technique which can be described as forcing a precursor solution through a capillary which is subjected to an electrical field. Of particular relevance for bone implants are coatings which comprise calcium and phosphate. The invention also relates to implants having a calcium and phosphate coating. A particular example of such an implant is a dental implant for the fixation of a dental prosthesis.
