3DMatrix porous coating

DJO Surgical has chosen an innovative approach to an industry standard for porous coating on their implants. This coating consists of small, three-dimensional (non-spherical) beads. The porous material is either commercially pure titanium or CoCr alloy, depending on the base substrate. The non-spherical shape of the beads provides more points of contact and a much rougher surface area.

Superior Surface Texture
The 3DMatrix^® porous coating is much rougher and aggressive than spherical beads, providing for more bone apposition. In a study for bone ingrowth, 3DMatrix porous coating outperformed spherical beads².

Aggressive Porous Coating
The 3DMatrix has a thickness of 0.5mm (a minimum of two bead layers), bead size 180-850 microns, and pore size of 250-450 microns. The porosity volume represents 61%. The pore size of 100 to 500 microns has been shown to be optimal for bone ingrowth ^1,2.
