Implant Fallen out
It's very possible that you could have lost a healing abutment. It's very common for patients to think that the healing abutment, because it is threaded like a screw, is the actual implant. I agree that you should return to your surgeon as soon as possible as they will most likely have to make a small incision to expose the implant in order to reconnect the healing abutment. Regardless, the best way to determine what actually happened is to return to your dentist as soon as possible.
Was it the cover screw that came off or the entire implant? The treatment varies differently on what happened. You should go back to the dentist who placed the implants and have them evaluated. Or you could post a picture of what fell out.
