1. Advances in Esthetics of
Implant Abutment
Restorations
Implant abutments have advanced
from titanium abutments to zirconia
abutments to hybrid abutments
improving esthetics with adequate
strength. It has further evolved to
lithium disilicate (IPS emax) hybrid
abutments.

6. This is where it started ..
Conclusion
Innovations in the field of Prosthodontics,
Implantology, Dental Material Sciences have made
possible for the clinicians to achieve esthetics with
implant abutment restorations in true sense.
This is where it has reached..
and the journey continues…
