What is the distal stem taper angle for Anthology Afit?

• A. 8 degrees
• B. 6 degrees
• C. 10 degrees
• D. 12 degrees

Answer: (C)

The distal stem taper angle is how sharply the bottom of the implant stem narrows as it extends into the bone. For the Anthology Afit, that taper is 10 degrees. This specific angle helps the stem seat securely in the canal and align with the modular components, balancing easy insertion with stable seating and favorable load transfer. If the angle were shallower, seating could be more likely to move micrometrically; if steeper, it could affect alignment or seating depth. So, 10 degrees is chosen to optimize these factors for this system.
