Summary

Implants have become the perfect solution for replacement of missing single teeth, partial or even complete edentulism.18 However, the dilemma of anterior implant-supported prosthesis is still not quite solved.19-21 Implant abutments are one of the esthetic influencers. And concerning the material, ready-made titanium abutments are considered the gold standard of all. Nevertheless, the esthetic properties remain doubtful. Lithium disilicate ceramics have been used as implant superstructures for many years now for their combined esthetic and biomechanical properties. The purpose of the present study is to evaluate the effect of using titanium implant abutment on the color of lithium disilicate crowns and the significance of masking the titanium abutments with opaque porcelain or using opaque lithium disilicate coping on the final esthetic outcome
