As I understand it, the difference here is that the root is removed during extraction and immediately replaced with the CNC-milled/"3-D printed" tooth.
I'm not entirely sure why the root needs to be in place before – perhaps the chances of the implant integrating with bone is better immediately after extraction?
Oh, I see, that is different. Frankly I'm surprised this works even when placed immediately after root extraction, but if so it would certainly be more "natural" than titanium screws...
