ABSTRACT:
A device is disclosed which has a solid interior and at least one surface which is porous. The porous surface has several desired characteristics, including: (1) the majority of pores have dimensions within a size range that encourages the migration of cells into said pores, such as about 50 to about 500 micron diameters, and (2) the pores have a controlled depth, such as about 300 microns or less. Such devices may be created by several methods, such as injecting casting material into a mold which is fitted with a shell of porous material having the desired shape and characteristics. Such devices are useful as artificial teeth and orthopedic appliances.
