Italians Perform Groundbreaking Full Jaw Transplant

statikuz writes "According to BBC News, Italian surgeons have performed the world's first complete jaw transplant. In eleven hours, the surgeons replaced a man's cancer-ridden jaw with a bone from a deceased donor; the donated jawbone was sterlized and stored at -196C to fight rejection, and "The current patient is said to be doing well.", says Professor Giuseppe Spriano, leader of the surgery team at the Regina Elena hospital in Rome."

      Yeah, what are the odds, you know? Out of all the temperatures to choose from, they just happen to pick that one...Truth is truly stranger than fiction. Obviously, cosmological fine tuning of physical constants make the molecular bonds of Nitrogen just right for them to go liquid at exactly the same temperature as they were keeping this guy's jaw. Absolute proof that there is a God. You heard it here first.

    Why does a jawbone need to be organic? Couldn't an artificial one be made of titanium or something?

      We're not that good at building implants yet. The human body is a rather hostile environment, really; bone has the advantage that it is continuously repaired.

      Exactly; Ti and other compounds need special treatment at the attachment points, while 'dead' bone still provides a better connective matrix, most likely.

      There was progress in using (dead, sterilized) coral for similar reasons, IIRC. However, dead people are likely less of an endangered resource, and already come in the rough shape you'd want.

      Why does a jawbone need to be organic? Couldn't an artificial one be made of titanium or something?

      It can. My dentist was installing metal (I think titanium) jaw part replacements into guys wounded in Vietnam. The problem is that the thermal and mechaincal properties of bone and titanium (or any metal) are very different. This leads to a lot of pain with slight temperature changes, mechanical shock like chewing, and so on. It's best to replace body parts using materials that are as similar as possible to the original. You can't get much closer that bone-for-bone.

    When you lose your jaw, and then you get a second jaw from a cadaver, everything you do with that new jaw seems more satisfying than before, because you realize how ephemeral your lower jaw really is. At any moment you might lose it again, so you want to enjoy every moment to its fullest.

    I bet right now this guy is chewing on the sweetest, juiciest Red Man chewing tobacco he's ever tasted!

    This is a bone transplant. (the article isn't clear, but you can't store living tissue at -196C, 77K you would kill the cells...)
    So issues regarding nerves and sensation are not a factor...

    It must be a pain to get a jawbone that matches size, it has to meet the tempomandibular joints on either side....

    steel rusts

    I have a surgical steel barbell in my mouth (through the tongue actually) for four years and counting... and guess what?
    No rust.
    It all depends on the quality of the steel, as this example proves.

    But I guess a steel jaw would be pretty heavy and uncomfortable though.

    I will be glad when we're able to make metallic bodyparts as full replacements for lost limbs, fingers, etc. Maybe one day, we'll be able to replace damaged body parts with Terminator like metal parts. How cool would that be to lose an arm, but replace it with an almost indestructable artificial limb? I'd just hate to see the guy on the news who is rushed to the emergency room because his metal hand crushed his johnson... Ouch.
