jim -
my understanding is that titanium alloys cause fewer problems across the board. "stability" probably isn't the best choice of descriptors for how they compare... but chromium is one of the more allergy-inducing implant materials, can accumulate to toxic levels in the human body, and cross-reacts frequently with other metal allergies.
every surgeon with whom i have spoken before and after surgery who uses implants in their practice stated that they would choose a titanium alloy, if available, above a chromium alloy. if one's choices are restricted, then obviously it's a risk/benefit analysis like anything else... but given a CHOICE, that is what they have told me - oral surgeon, several orthos, endodontist.
autoimmune diseases, as i mentioned, are a special breed, and are to be deal with using major caution! again, i'm NOT the expert in autoimmune diseases, but i have a healthy fear of them!!
