Both provisional IFCDs were delivered, and the buccal SAHs were masked with resin in an attempt to match the tooth shade as accurately as possible (Figures 3, 4, and 5).
Case one: maximum smile after masking with resin.

Finally, a combination of an implant- and abutment-level (only on the left maxillary posterior implant) splinted IFCD with a milled zirconia framework, which was layered with lithium disilicate on the anterior teeth, was fabricated and delivered (Figures 6 and 7).
Case one: maximum smile after installation of the final IFCD with lingualized SAH using DA.

For case two, to correct the buccal SAHs in the anterior two implants, the lab was instructed to fabricate an abutment-level splinted milled zirconia framework with individual lithium disilicate crowns for the buccal SAH sites (Figures 8 and 9).
Final milled zirconia framework with individual crowns in case two: individual Emax crowns fabricated to be cemented intraorally.
