Case report: NobelProcera ASC Abutment

Figure 1a. Initial situation: Female patient, 29 years old. Agenesis of both lateral superior incisors. Maryland porcelain bridges with continuous descementations. Thin biotype with long papillae; good oral health and hygiene. 2-3 mm of bone width was available in both areas of the ridge. There is not enough bone to place implants and there are sunken areas in the gingiva.

Figure 2a. Removal of the Maryland Bridge A connective tissue graft was performed to change the biotype from thin to thick. This was followed by three months of healing. Then a guided bone regeneration with two blocks from the mandible ramus was completed, followed by eight months of healing. Two 13mm NobelActive NP implants were then placed.

Figure 3a. A second connective tissue graft was performed to improve the height of the soft tissue.

Figure 4. Fixed provisional restorations were placed to shape the emergence profile.

Figure 5a. Final CAD/CAM restorations: Abutments were designed from a diagnostic tooth set-up to create the ideal anatomical shape for optimal veneering. The new restorative flexibility which the NobelProcera ASC abutment enables a labially positioned screw access hole to be rotated and placed palatally.
