Apparently implants have been made for over 100 years, even before titanium was 'discovered' in the 60s.
The best bet we have to replace that are root-analogue implants [1] - essentially a physical 3D-printed copy of the whole tooth, including roots. Unfortunately information is scarce (as you can see in that wikipedia page), it's not even mentioned in the main 'Dental implant' article. There is a single dentist in the entire world [2] actively offering these implants, and going at it for 20 years.
