摘要：
Implants are formed from a multiple staged process that combines both additive and subtractive techniques. Additive techniques melt powders and fragments of a desired material, then successively layer the molten material into the desired implant shape, without compressing or remelting for homogenization of the layers, thereby producing an implant that is substantially free of pores and inclusions. Subtractive techniques refine implant surfaces to produce a bioactive roughened surface comprised of macro, micro, and nano structural features that facilitate bone growth and fusion.
