I am in a similar situation, although maybe not quite as bad. Can't remember how many root canals I have, at least a dozen crowns, and 2 implants (bottom molars, one on each side).
Concerning the bone loss, implants do not do well with bone loss. You really need to see what you can do to strengthen your bones. I spent 7 years abroad with no access to milk, and the lack of calcium affected my teeth to the extent that bits started breaking off. Coming back to this country and drinking milk again stopped that. For the last decade or so I have also take calcium citrate twice daily and Vitamin D daily to ensure my bones stay in good condition, and they have.
My biggest problem now is the gums. All those crowns and implants wreak havoc on the gums if you let up on care at all. Currently I brush in the morning, brush and floss after meals, and brush, floss and use a water pik every evening before going to bed. Just wish I had started doing this much earlier.
I went with implants because they should last longer and not damage the nearby teeth. However, I did not need a bone graft to do them.
