Three-dimensional Custom-root Replicate Tooth Dental Implants.

This article summarizes the accomplishments and knowledge gained over the past 2 decades with respect to immediate dental root analogue implants (RAIs). It discusses how the artificial nature of the present dental implant materials and unnatural shapes cause complications, posing a threat to long-term biointegration, and how RAIs will influence the way that implants are produced. Will an osseointegrated RAI be the optimal immediate replacement for extracted teeth in the future? How will three-dimensional printing be involved in these more biomimetic RAI systems? The present research and developments seem promising and will continue to shape the future of implant prosthodontics.
