Plugs can be broken in a number of ways, over tightening, dropping, piston hitting them, etc., etc..
You will need to determine if it was broken because it was the wrong plug, if it was hitting the piston or some other internal cause.
You will also need to determine if any of the ceramic or metal was left in the cylinder and it is likely it was.
That will need to be removed to make sure it does not cause any further damage.
If there was excessive oil it is likely that the damage has already been done.
