There's a hole in my implant. Do I need to redo it?

It is possible that the filling material covering the screw access hole on the implant prosthesis has partially come out, which is not a major issue.
If it is just slightly rough, no refilling is needed; if it is deep enough that food gets stuck, the hole can be refilled.
In rare cases, the implant prosthesis itself may have fractured, in which case only the prosthesis may need to be remade.
