Fusion Interface


When replacing missing teeth with dental implants, it is essential to control all factors that influence their survival and success rates. The implant-abutment-interface is crucial for the longevity of dental implants, which represents the physical connection between the prosthetic restoration, the abutment and the implant body.

The abutment or connection has important functions, such as maintaining the prosthetic restoration stable and linking it to the implant system. In implant dentistry, conical connections are the state of the art in terms of durability, strength and load distribution.

Through accurate protocols and high precision manufacturing using the latest technologies, NDI Medical Implants have achieved outstanding clinical functional and cosmetic results with the fusion implant-abutment-interface.

The importance of the implant-abutment interface in every day implant dentistry

A precise fit between the implant body and the abutment is essential for the long-term stability of the entire implant system. Hence, the implant-abutment interface has several mechanical and biological functions, including:

  • Promote even load distribution
  • Decrease micromovements of the implant
  • Provide mechanical strength
  • Improve resistance to heavy loads
  • Decrease the risk for implant fracture
  • Reduce marginal bone loss
  • Provide a tight seal of the interface, decreasing formation of microgaps between implant and abutment, thus preventing bacterial penetration, adhesion and colonization.
  • Prevent development of peri-implant mucositis and peri-implantitis.
  • Provide predictable clinical results and increase long-term success.

Under less than ideal conditions, unstable connections can lead to abutment overloading, screw loosening, alveolar bone loss, implant fracture, and potential implant loss.

High precision conical hex-connection

The first dental implants in the market were produced with external hex connections. Later, they were upgraded to internal hex connections for better load distribution.

More recently, high precision conical connections have been developed, which have taken dental implantology to the next level. Stress transfer between the implant system components and between implant and alveolar bone is optimized when critical components are located inside the implant body, such as in the conical connections.

The geometry and design of the conical connections used by NDI Medical Implants provide the best foundation for well-functioning implant-based restorations.

In order to assure high quality standards, NDI Medical Implants only manufactures conical connections with platform switching. In vitro fatigue tests have confirmed the efficacy and predictability of our connections.

Platform switching for ideal soft tissues

When an implant abutment is smaller than the implant platform itself, the connection is described as platform switching or platform shifting. The platform switching concept assures adequate volume for the soft peri-implant tissues due to the creation of additional space, leading to healthy gingiva, excellent cosmetics and increased patient satisfaction.

Achieving ideal gingival tissue volume around an implant is one of the most critical factors to avoid loss of marginal bone, leading to successful and stable results in cosmetic areas.

According to the initial study on platform switching from 2006, the reason for the better results associated with this concept is the improved biological space, which keeps any inflammatory infiltrate away from the alveolar crest.

Several clinical studies have been performed since then and all of them agree on the improved benefits of platform switching in terms of bone preservation. The transition between the
prosthetic restoration and the implant body becomes better with the platform switching from a biological and mechanical point of view.

NDI Medical Implants has invested all necessary resources into the production of machined conical connections with platform switching that can resist loading conditions with high stability and optimal force distribution.

The superior characteristics of the fusion interface offered by NDI Medical Implants avoid mechanical complications, providing the ideal conditions for maintaining healthy soft and hard tissues around the implant.

Because most failures regarding dental implants are related to the implant-abutment interface, NDI Medical Implants only works with the best components to guarantee long-term success and tissue stability.
