Silicon Nitride Coating. With a similar chemical composition as our other forms of silicon nitride, this form of silicon nitride can be applied as an adherent coating to metallic substrates, including cobalt-chromium, titanium and steel alloys. We believe applying an extremely thin layer of silicon nitride as a coating may provide a highly wear-resistant articulation surface, such as on femoral heads, which may reduce problems associated with metal or polymer wear debris. We also believe that the silicon nitride coating can be applied to devices that require firm fixation and functional connections between the device or implant and the surrounding tissue, such as hip stems and screws. The use of silicon nitride coating may also create an antibacterial barrier between the device and the adjacent bone or tissue.

Exactly as I suspected. If silicon bonds to titanium and silicon nitride bonds to ceramic then there's no reason why a silicon nitride coating wouldnt allow a better bonding rate for porcelain. Unless you want your false teeth black,purple, blue or rainbow. For antibacterial dentures.
