  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
  2. 2. Two Different Approaches:Hybrid abutment & crown Hybrid abutment crown INDICATIONS : Anterior and posterior single-tooth restorations. CONTRAINDICATIONS: Ti base doesn’t fulfill the•The marginal shoulder width SA 0.6 mm. geometric requirements. •The marginal shoulder width SA at least 0.6 mm.•An emergence profile with a right angle at the transition to the crown. Failure to observe •The wall thickness W AK larger than 1.5 mm for the entire circumference.•The wall thickness W A at least 0.5 mm. maximum and minimum•The height HA should not exceed twice ceramic walls. •Screw channel opening not in contact areathe height of the Ti base HTi. or area with masticatory force.

  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
