Why do my abutments get loose and fall out?

I recently had the final stage of my denture implant completed with the abutments put in. It was very painful and I had to have novicane. Within one week, when I took my denture out to clean, the abutment fell out of my mouth.

I went back and went through the procedure again. Within two days I knew something was wrong with the abutements again and when I took the denture out, the other abutement fell out. Are they not being put in right? I had two implants put in 25 years ago, it was a different type - not an abutment, but made as part of the denture - never a problem for all these years until this year when one of the implants just sheared off.
