Figure 2: The implants are more than 4 mm below the gingival level. The gingival emergence profile is increased slightly on the master model. This facilitates the fabrication of temporary restorations with a more harmonious sub- to supra-gingival coronal transition and more suitable dimensions at the gingival 1/3 of crowns 11 and 21.
















Figure 3

Figure 3: After minor gingivoplasty, temporary restorations 11 and 21 are fixed to the implants. They maintain the emergence profile and guide the gingival healing. A porcelain-fused-to-metal restoration 32-X-X-42 is fixed to the implants (Laboratoire dentaire Artech).

Figure 4: The final shape of abutments 11 and 21 is produced using a Procera CAD 3D program. Each abutment is designed and adjusted labially and interproximally (photo: Mr. Gunnar Bagge, Nobel Biocare, North York, Ontario).
