About us

At Nobel Biocare we don’t develop individual products but entire solutions for fully functional, natural-looking results that aspire to last a lifetime. All components complement each other in a precisely harmonized system to help ensure long-term clinical performance and cost efficiency for both clinician and dental laboratory.

Designed and tested as complete systems

A system is only as strong as its weakest link. The performance of any component depends not only on the component itself but also on its interactions within the system.

As a result, the appropriate test of any component is within the system it's part of. We conduct research and testing not only on individual components such as implants, abutments and screws, but always on the entire system too. This way, we ensure that our solutions function safely and reliably for many years.

The importance of a perfect fit

Whether they're used with our implants or those from other manufacturers, all our restorations are designed for a precise fit between abutment and implant. Selecting an abutment with a precise fit is crucial for system performance, as it ensures that occlusal forces are distributed evenly. It also helps avoid uncontrolled peak stresses. Any mismatch can lead to extreme load and stress conditions that may cause individual components or the entire system to fail.

Why the clinical screw matters

Our abutments are delivered with a dedicated clinical screw that is optimized for the implant-abutment system that it’s part of. Depending on the abutment, connection type and platform size, screws come with or without a surface coating. The absence or presence of the coating and the coating type all impact the preload (the tensile force created when tightening the screw). 

We select the most appropriate screw type for each and every implant-abutment system, ensuring a tight and stable fit for long-term performance.

Original vs. look-alike abutment screws - will you get the same result?

  • Different macro design
  • Different material
  • Screw surface not optimized for the abutment type
  • Poor screwdriver interface

Mismatching components can result in insufficient preload. This leads to increased motion between the system components, which causes screw loosening and component failures. In addition, poor screwdriver interfaces can cause problems when you need to remove the restoration.

Substitutes can put patients at risk

The use of substitute components means that the parameters governing system performance are no longer controlled. In the example of maximum joint compression, which defines the load that the implant collar can bear, a substitute may result in a force that is higher than the allowed maximum, causing the implant to fracture.

To avoid this, the peak forces have to be distributed in a controlled way. This can only be achieved by using high-quality and precision-manufactured components that have been designed for, and tested with, the system they are a part of.1
