Needle-like apatites were successfully formed on titanium plate, bar, and mesh by a hydrothermal-electrochemical method below 200°C in an electrolyte containing calcium and phosphate ions. The deposited needle-like apatites were homogeneously and vertically oriented to the substrate surface. Morphology and crystallinity of the deposited apatite were easily regulated by the electrolytic conditions such as composition and temperature of electrolyte, current density, and substrate. It was confirmed that the electrochemical deposition of apatite had great effect on the promotion of the bioactivity of implant. Furthermore, we applied to produce a novel fabrication method of a composite membrane consisting of oriented needle-like apatite and biodegradable polymer for tissue regeneration in dentistry and medicine.
