NobelProcera® angulated screw-channel abutment ASC Metal adapter Precision of fit: Predictable retention between adapter & Zirconia Mechanically retained: Easy to use: removal & re-insertion during veneering in lab No need for cement Benefit: Predictable retention and resistance Time efficient handling in the dental lab or clinic No irritation of mucosa due to cement between adapter and abutment body 2.
NobelProcera® – peace of mind Clinical issues caused by excess cement: Implant cement can act like a foreign body in the mouth. Residual cement in the mucosal margin effects the patient’s soft tissue, causing e.g. soft-tissue hyperplasia or recession and may even lead to bone loss. Even the most diligent of clinicians may sometimes miss residual sub-mucosal cement in implant cases. Sometimes, it may not immediately be apparent that there is residual cement - and the effects can be delayed for years after cementation. Due to known issues related to cementation clinicians tend to prescribe screw- retained implant restorations over cement-retained.
Screw-retained vs. cement-retained restorations Screw-retained restorations show lower failure rates, but overall, the difference in survival between cement- retained vs. all types of screw-retained is very small to none1,2. Screw-retained restorations exhibit fewer technical and biological complications2: Screw-retained: 7.50 (95% confidence interval: 5.37 to 10.47) per 100 life years Cement-retained: 9.81 (95% confidence interval: 6.6 to 14.6) per 100 life years Additionally, two-piece screw-retained restorations were lower in failure than one-piece screw-retained restorations2. 1 Cicciu M, Beretta M, Risitano G, Maiorana C.

NobelProcera® ASC Abutment Efficient screw-retained design with cut-back function ? This anterior restoration shows multiple challenges: Position of screw access hole, projecting from labial aspect of the crown Current design shows no support for the veneering material Optimal screw-retained crown design
NobelProcera® ASC Abutment Efficient screw-retained design with cut-back function Select "cutback from crown" - this brilliantly triggers a pre-defined diagnostic cutback from anatomic virtual crown Make sure to increase the number of handles and rows Select the desired shoulder type and ceramic thickness (veneering support can be altered to your ideal preference) Drag and drop the handles to further adjust the anatomic design
Abutments on Conical Connection WP will be available Q1 2015 NobelProcera® ASC Abutment Restorative flexibility with angulated screw option Angulated screw channel abutments are available for Conical Connection NP and RP abutments in Zirconia. Select in the scan module one of the 3 production type options for conical connection: ASC Angulated (description) ASC Straight Straight In case you would like to design the case first and decide on a later stage, you can select ASC through Rx Menu or simply activate the screw channel design icon later during the design.
NobelProcera® ASC Abutment Restorative flexibility with angulated screw option Activate screw channel design icon Easily move the screw access hole to the ideal position - this can be done by dragging the blue screw axis white handle to any angle of up 25 degrees at a rotation of 360 degrees Green cylinder represents screw channel diameter and direction. When displayed green - this illustrates an acceptable angle If an unacceptable angle is designed, the channel changes to a red color
NobelProcera® ASC Abutment Restorative flexibility with angulated screw option NobelProcera software is fully integrated into NobelProcera production securing that the required material thickness is always met. In cases where manual refinements have been made, it is necessary to eliminate all red areas (warning areas - illustrating minimal material thickness violation): use abutment design tools as for any other abutment type

NobelProcera® ASC Abutment Addressing daily challenges Anterior challenge: For many anterior cases the screw access hole of the abutment has to be covered by a cement-retained crown if an esthetic outcome is to be achieved. Your benefits with ASC: Restorative flexibility to place the screw access hole in a position that creates optimal esthetics. Cement-free: Intelligently designed mechanically retained adapter.
NobelProcera® ASC Abutment Addressing daily challenges Posterior challenges: Secure handling and access with tooling in the posterior region can be challenging in situations with limited interocclusal distance (vertical space). Occlusal function may be hindered due to position of screw access hole on screw-retained crowns. Risk of leaving residual cement. Your benefits with ASC: Easy access to restoration with the option to position screw access hole mesially. Work easily with the pick-up function and securely hold the screw using the Omnigrip Screwdriver. Optimum occlusal function (screw access hole can be positioned in ideal place for optimal occlusal function). Cement-free: Intelligently designed mechanically retained adapter.
