Abstract: 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.

Abstract: Inorganic composite membrane containing molecular sieve crystals, comprising a macroporous support to which molecular sieve crystals and modifications thereof have been applied substantially as a monolayer, said crystals and modifications thereof having been oriented so that, toa substantial extent, the pores of the sieve crystals form a significant included angle with the support surface, there being present between the crystals a gastight matrix, at least gastight to a degree sufficient under practical conditions.
