A master cast was fabricated in conventional fashion. The previously fabricated Final Encode Abutments were placed onto the master cast (Figure 16). Wax patterns were developed to full contour and a facial silicone index was made (Figure 17). The wax patterns were then cut back for porcelain application (Figure 18). The castings were placed onto the master cast. The facial silicone index identifies the initial contours to be established in porcelain (Figure 19). The Final Encode Abutments were removed from the master cast and placed onto the verification cast for final interproximal contacts (Figure 20). The definitive porcelain contours were finalized on the verification cast. The definitive crowns were fabricated on the Encode Abutments and the dies of the natural teeth (Figure 21).

The pre-established full contours of the wax patterns were consistent with the contours of the definitive restorations (Figure 22). The silicone index confirmed that the facial and occlusal contours of the definitive implant restorations replicated the original contours of the full contour of the wax patterns (Figure 23). The anatomic emergence profiles developed in the provisional crowns were also replicated. Note that the implant and crown restorations were fabricated on one master cast (Figure 24).
