Esthetics were also compromised due to inappropriate width/length proportion at 117-105% (Figure 3).

The diagnostic wax-up (Figure 5) was done to accomplish multiple objectives like establishing an accurate incisal guidance and verifying the esthetic and functional modification of dentition.

The incisal edge position and contours were simulated with the help of silicone putty indexes from the composite restorations (Figure 8). The final crowns and fixed partial dentures (Figures 8 and 9) were cemented in self-adhesive composite resin cement (RelyX Unicem, 3M ESPE, St.
