The Straumann® synOcta concept was introduced worldwide in 1999, using the well-known Morse taper design principle developed in 1986. The mechanically locking friction fit of the synOcta® internal connection, with an 8° cone and an octagon for the repositioning of prosthetic parts, shows improved performance over traditional external connections. Abutment loosening, even in screw-retained situations, has virtually been eliminated.
The Straumann® Narrow Neck CrossFit® Implant is the latest addition to our Soft Tissue Level implant portfolio and features the CrossFit® connection.
The self-guiding internal prosthetic connection has an optimized design for long-term mechanical stability under all loading conditions and ensures an exact fit between implant and abutment. The internal cone of 15° stands for greater flexibility in prosthetic treatments. Four internal grooves ensure the precise positioning of prosthetic components.
Depending on the implant diameter, the Bone Level Implant is equipped either with the Regular CrossFit® (RC) or the Narrow CrossFit® (NC) connection. The latter is also featured in our new Straumann® Narrow Neck CrossFit® implant.
