Implant that's screw retained

I had a dental implant that was screw retained and put in, in 2016. In 2023 I was told that it was loose and they weren't able to tighten it and broke it. They then cemented it in in 2023 without discussing with me that it was no longer going to be screw retained. It continues to fall out. What would be the reason that it couldn't be re-installed being a screw retained implant? It was never discussed with me as to what they were doing or that it was no longer going to be screw retained
