  90 days would probably be enough for a bone to set. But given that the wiring was threaded between the teeth, the sutures would be subject to the digestive enzymes of the mouth, which are significantly more aggressive than anything outside of the digestive system.

    They could have periodically replaced it if it was only wrapped around the teeth. Changing a bandage is a pretty normal part of medical care. Changing the cast periodically is a routine part of modern treatments for club foot in children. The assumption that it had to last X amount of time is questionable.

      I agree, but another problem with gut is that it stretches under load when moist -- one of the issues with catgut strings on instruments is that they can't hold a tune, and that's much worse on hot & humid days (digression, they sound great though... much like nylon). Gold is also malleable, but can take quite a bit more tension before failure and work-hardens where catgut undergoes plastic deformation. The other point I'm less certain of is that the discovery was based on dental calculus... I suspect that this wouldn't have been so pronounced if the thread was replaced frequently.
