Lemme tell you about implants. There are hundreds of systems on the market, and they are not compatible. Each requires proprietary supplies and tools. I just had a crown come off my 25+ year old implant, and no one can put it back onto the implant (which is in fine shape, as is the porcelain crown) because the "state of the art" back then is swamped by the new stuff. It would simply require a tiny setscrew, but no one knows what to order, what that esoteric system was in the late 1990s, or if it would even work if we had it. If the tooth root is still viable, get a crown.
