Angulated Screw Channel

Simplified management of challenging cases with a cement-free angulated screw channel solution in both anterior and posterior indications.

The Angulated Screw Channel enables delivery of a screw retained restoration in many cases where a labial-facing screw access hole would traditionally require a cement-retained solution. Additionaly, for posterior cases where limited opening/access might be a concern.

Expert insights

20:58-22:17. Dr. Wong shares his insights on several major aspects of posterior implant rehabilitation. Both the surgical and prosthetic features of the treatment plan are covered: type, size, number and distribution of implants, prosthetic and abutment design, material selection, hygiene considerations, and more.
18:17 - 19:59. Mr. Rensburg discusses how his laboratory team best supports clinicians through the utilization of today’s technologies and how that has enabled them to be more successful.
Starting at 10:28. Detailed explanation of the Angulated Screw-Channel (ASC) System - components and design. Also includes argument for screw retained. NOTE: this video shows Angulated Screw Channel on a Tri-Lobe connection. This feature was during beta testing only and was never offered as a product.
Explanation of the Angulated Screw-Channel (ASC) System. Supported by a posterior and anterior restoration example, the lecturer team presents the advantages of this approach and gives handling insights from both clinical and laboratory perspectives.

With the ASC abutment and Omnigrip driver, angles of up to 25 degrees deviation from path of the abutment screw to the implant channel can be reconciled. This has become an important tool in the anterior and posterior regions.

Treatment Histories

Immediate implant placement with submerged healing and subsequent soft tissue management. Due to the palatal angulation of the implant, the definitive restoration was fabricated using a ceramic-veneered-to-zirconia Angulated Screw Channel (ASC) abutment.
This 33 year-old, male patient's chief complaint was a missing lateral incisor which had been extracted several years earlier. The site presented significant loss of hard and soft tissues which could eventually compromise the aesthetic result of implant treatment. The overall health status was good; therefore, a one-stage implant procedure simultaneous to connective tissue grafting and the use of a slim healing abutment was planned. Final restoration with Angulated Screw Channel.

"Introduction of the NobelProcera® ASC (Angulated Screw Channel) with the accompanying Omnigrip™ screw and Omnigrip™ screwdriver offer an option whereby the long axis of a crown can vary from that of the implant by as much as 25 degrees and still permit the crown to attach to an implant without the need for an intermediate abutment."
