The Straumann implant system used at UAB is defined by which connection angle?

• A. 10 deg cone hex connection
• B. 15 deg cone crossfit connection
• C. 20 deg tapered connection
• D. 25 deg flat connection

Answer: (B)

The Straumann implant system, particularly the connection design known as the Cone Morse connection, features a 15-degree angle, which is optimal for achieving stability and maximizing the surface area for the implant-abutment interface. This angle not only aids in securing the abutment to the implant but also provides a favorable distribution of forces during occlusal loading.

The tapered design of the Cone Morse connection facilitates self-centering of the components, which reduces the risk of misalignment during placement. The 15-degree angle enhances the mechanical interlocking between the implant and the abutment, thereby minimizing micro-movement that could lead to complications such as biomechanical failure or aseptic loosening.

In the context of dental implants, understanding the specifics of the connection geometry, such as angles and shapes, is crucial for predicting the performance and longevity of dental restorations. This is why the correct choice focuses on the 15-degree cone crossfit connection specific to the Straumann system utilized at UAB.
