putting dental implants when you have osteoporosis

I had to have upper and lower implants put in about 3 years ago and I have had lots of problems due to not having enough bone due to osteoporosis medication, which I told the prosthodontist I had taken Boniva for 5 yrs prior to being told I need implants. I had to have bone added to some areas several times in order to place the implants. The dentists I see now said I shouldn’t have gotten them and the prosthodontist shouldn’t have said I was good to go. Due to a failed implant I had to have the bottoms redone. I don’t mean to worry you or anything I just thought I should tell my story so that anyone considering implants that took osteoporosis meds can make sure the dentist checks to see there is enough bone before proceeding. A second opinion is good to get too. Also they are very expensive. Full set cost me 60K. Pain isn’t too bad just the waiting for the process to be over.

My question is a bit different than what is discussed above. I have 4 dental implants in my lower jaw ("all on four") which were very tricky to put in as I had so little jaw bone evn after bone grafting. With osteoporosis will I lose even more bone in my jaw and potentially lose all my lower teeth? I am 55 ans my osteoporosis is moderate to severe. -3.5 L hip, -2.5 r hip and lower spine. I am very stressed. There are no other options if I lose my teeth as I have insufficient bone even for floating dentures. Has anyone had a similar experience or insight to offer?
