The invention is an enossal implant with a coating that accelerates the healing-in process and counteracts demineralization of the bone when the cavities that are necessary for insertion of the implant are made. The invention elevates the osmotic pressure in the immediate vicinity of a freshly inserted implant so as to compensate quickly for the loss of salts and minerals of the chemical compounds and minerals contained in the bone and the bone fluid when the cavity is made. The surface of the implant may be, for example, coated with a dry crust of soluble NaCl crystals, which dissolves gradually after the insertion.
