Yes. It's a 3-parts system. Makes it easier to replace broken parts.
They drill a hole - 1/4 inch wide and about 2 1/4 inches deep - and insert something like a Rawlplug (TM) [sorry, no idea what you Americans call it] with a thread on the inside. It actually gets hammered into place.
Then they sew the flesh up over it and let the bone grow around the metal for a few months. After that, they cut the flesh open again, insert a screw with a little screwdriver and fasten a crown to it.
My dentist's table looked like a mix of a medieval torturer's and a modern DIYer's toolbox
