The self-tapping Dynamic Thread®, protected by SDS, varies in depth and angulation, compared to competitors, resulting in a higher implant surface. This design facilitates engagement of the implant to the bone at the point of insertion.1 Even under challenging bone conditions, the Dynamic Thread® secures initial implant stability, which is a prerequisite for successful implant osseointegration.¹⁻⁶

Key Takeaways

💡

• Primary stability regardless of bone class
• Safety for immediate protocols
• Optimal bone-to-implant contact
• Enhances vascularization area
• Optimal balance between torque and thread design
• Facilitates osseointegration
• Simple and stressless for the clinician

Clinical Advantages for Surgeons

Dynamic Thread® provides an immediate grip during insertion because of its self-tapping capability, which prevents heat generation⁶⁻⁷, spinning, and fracture.
This allows for a greater thread depth into the bone, regardless of the bone class, resulting in:

Implant Thread Comparison Table

Thread design	Thread depth	Thread form	Thread pitch**	Tapered	Stress forces distribution	Adaptation to bone class
SDS	Varying	Sawtooth	0,7 mm	✅	✅	✅
Competitor 1	Nonvarying	V-type	0,8 mm	❌	❌	❌
Competitor 2	Nonvarying	Square	0,8 mm	❌	❌	❔
Competitor 3	No threads	No threads	No threads	❌	❌	❔

❗

These findings indicate that SDS Dynamic Thread® ensures a high level of safety for immediate implantation and loading, irrespective of the bone condition.

Varying thread depths provide stability in all bone classes. Nonvarying threads require higher torque, increasing the risk of bone necrosis (in bone class I) or spinning (in bone class IV). Competitor thread designs have fewer threads, reducing the surface and bone-to-implant contact. Additionally, they lack sharp cutting edges thus they generate more heat during implant insertion.
