Restorative flexibility and easy handling
Solve the esthetic challenges faced when screw-retained solutions are placed in the anterior and improve occlusal access in the posterior.
The angulated screw channel (ASC) provides the option to place the screw access hole anywhere between 0° to 25° in a 360° radius. This means you can now restore almost any situation with a screw-retained restoration and remove known risks associated with excess cement.
What's more, the angulation allows the use of screw-retained restorations in the esthetic zone by avoiding a buccal screw access point, and the metal adapter means it's now possible to use zirconia implant restorations in the posterior.
The ASC function is available when restoring on Nobel Biocare conical connection implants.
Products with the ASC function:
Situation: Ectodermal dysplasia cross-linked with multiple congenitally absent teeth leading to typical occlusal disorders. These agenesia are associated with severe alveolar bone atrophy.
Solution: Placement of six NobelReplace CC NP implants using NobelClinician software and guided surgery. Six NobelProcera ASC Abutments serve as screw-retained restorations.

Situation: Fractured maxillary right central incisor. Tooth is hopeless and extraction is planned. Insufficient periapical bone.
Solution: Bone and connective tissue grafts. NobelActive implant placement with provisional crown. Use of NobelProcera ASC Abutment for final restoration to avoid screw access hole being located labially.

"For our practice [the ASC] has been the most important step forward in 2015... We like to call it a game-changer"
"These new solutions give both the restorative dentist and the dental technician more options. Greater flexibility helps ensure the best possible treatment outcome. Thanks to the free placement of the screw axis, the visual properties of the ceramics, such as translucency, can be optimized while preserving the advantages of a screw-retained solution.”
“How many cases do we know where the screw access hole would come out at the
“We can get the screw channel in the ideal spot for both esthetics and strength, as well as for ideal placement of the final restoration. This is just fantastic."
