@entity4625 -gel-derived @entity3759 coatings are known to promote bonelike @entity692 formation on their surfaces in vitro and in vivo. @entity692 integrates into bone tissue. In some clinical applications, the surface of an implant is simultaneously interfaced with soft and hard tissues, so it should match the properties of both. A new method is introduced for treating the coatings locally in a controlled manner. The local densification of sol-gel-derived titania coatings on @entity702 substrates with a @entity515 laser was studied in terms of the in vitro @entity78 -inducting properties. @entity515 -laser-treated multilayer coatings were compared with furnace-fired coatings prepared with the same recipe and previously shown to be bioactive. Additionally, local areas of furnace-fired multilayer coatings (previously shown to be bioactive in vitro) were further laser-treated to achieve various properties in the same implant. Topological surface properties were examined with atomic force microscopy. The formation of @entity692 was studied with Fourier transform infrared and scanning electron microscopy energy-dispersive X-ray analysis. The results show that @entity78 formation can be adjusted locally by laser treatment. @entity78 is a bonelike @entity692 . The local treatment of sol-gel-derived coatings with a @entity515 laser is a promising technique for creating implants with various properties to interface different tissues and a possible way of coating implants that do not tolerate furnace firing.
