NobelActive™ - designed and proven for strength

fatigue strength

Fatigue strength is the maximum force an implant/abutment combination can survive for at least five million cycles. Nobel Biocare developed a protocol for testing fatigue strength in 1992. Today, the International Standard for single-post endosseous dental implants fatigue testing (ISO 14801) is used, which is very similar to the original Nobel Biocare protocol.

ISO 14801 protocol:

• Implant/abutment combinations mounted in 30° off-axis orientation
• Cyclic force applied (frequency 14 Hz)
• 5 million cycle duration

The fatigue strength results are presented below; comparing NobelActive™ with the “gold standard” for benchmarking fatigue strength. 

 implant placement validation

The maximum insertion torque for NobelActive™ was established at 70 Ncm, based on clinical study results(1):

• Implants were placed with varying insertion torque levels
• No correlation was found between complications and insertion torque at these levels, when compared (Unpublished data)

torque strength

NobelActive™ was designed with high torque strengths in mind:

• 282 Ncm maximum implant torque strength for NobelActive™ Ø3.5
• 452 Ncm maximum implant torque strength for NobelActive™ Ø4.3

When compared to the maximum insertion torque, a significant safety margin exists (see figure below). For further NobelActive™ mechanical testing information, see the NobelActive™ Technical Story.
