"SDS Facts" #7: Primary Stability

1.12.2025 · 3 min


In the conical tapered apical area of SDS implants, the deep Dynamic Thread® depths provide the immediate grip necessary for initial stability, even in cases of low bone quality or minimal apical bone volume.¹⁻²

In this report case, due to their stability in the apical region, SDS implants could be loaded immediately, despite the initial bone condition.



Key Takeaways


💡
• Distinctive apical design
• Comfort while placing
• Security for immediate stability regardless of bone quality and quantity



Clinical Advantages for Surgeons


During the insertion of the implant, the conical tapered apical design and its Dynamic Thread® deep threads ensure immediate grip into the bone, resulting in:

1.
Very high stability
Option of a torque range of 35-70 Ncm3-7

2.
Immediate grip

SDS implants are the only ones with a conical, tapered apical design and a deep, large Dynamic Thread®.

Different thread depths provide stability across all bone classes. Non-varying thread depths require higher torque, increasing the risk of bone necrosis (in bone class I) or thread stripping (in bone class IV). Competitor thread designs feature fewer threads, reducing the surface area and bone-to-implant contact. In addition, they lack sharp cutting edges, which causes greater heat generation during implant insertion.
