  1. 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.Slide No. 1 Dr. Aditi Sabnis. Poster No.21

  6. 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… Slide No. 6 Dr. Aditi Sabnis. Poster No.21
