Wow, Rick . .. very infomative post - thanks!

I'm guessing (hoping) that the "cracking" was a torque wrench popping. (?)

I hadn't thought about what a bridge does to the anchoring teeth . .hmmm.

Also, I thought implants typically lasted a lifetime. 20 years would put me at 59. (assuming the rest of me makes it that far.) . . .hmmm
At that point, (20years later) is "the fix" usually just the replacement "tooth"? It must be. After all, the dental implant anchors are screwed in, and the bone is supposed to grow into the Titanium.
