Living abroad post-surgery as a US citizen

[trimixmaster-mike]

Greetings friends,

As a US citizen I'm considering acquiring an implant here in the states.
But then I am considering taking a job abroad for a while where the status of high-volume/experienced implant surgeons, should repairs or replacements be necessary, are unknown. This location has not been decided upon yet. I am pretty committed to the surgery at this point but it's unsettling to think of ultimately residing long-term somewhere where help is thousands of miles away. The thought generates a reasonable amount of anxiety for me.
Has anybody else been in a similar situation?

Wishing you all well
