On1™ concept

Preserve the connective tissue structure and
maintain full restorative and surgical flexibility.

What is the On1 concept?

The On1 concept is unique. It's the first concept to preserve the connective tissue structure, and maintain full restorative and surgical flexibility.

The concept also radically simplifies the restorative procedure, as the On1 Base moves the restorative platform of Nobel Biocare conical connection implants from bone level to tissue level. It remains in position from implant placement to finalization, which leaves the soft tissue undisturbed for optimized healing.

Main benefits

Preserve the connective tissue structure

The connective tissue structure is left intact as the On1 Base remains in situ during the entire restorative workflow and throughout the lifetime of the restoration.

Simplify all restorative procedures

The On1 Base moves the prosthetic platform from bone level to tissue level. This makes attachment of restorative components and impression taking much easier as the connection is clearly visible. 

Gain peace of mind

The On1 Base has a unique prosthetic connection, ensuring that only precision-engineered Nobel Biocare restorations are used.

Maintain surgical flexibility

The On1 concept can be used with any Nobel Biocare conical connection implant system, each designed for high primary stability and built-in platform shifting. These include NobelActive, NobelParallel and NobelReplace implants.

Two workflow options

The On1 concept provides you with the option to follow the conventional impression taking workflow or the intraoral scan workflow using the special On1 IOS (Intraoral Scannable) Healing Cap. For easier handling, key components are delivered with a pre-mounted holder.

Conventional impression taking workflow

The On1 Base stays in position while the healing cap, temporary restoration, impression coping and final restoration are placed.

Increase workflow efficiency with intraoral scanning

Save chair time with the On1 IOS Healing Cap, which supports an intraoral workflow. This eliminates conventional restorative procedures, including impression taking, while also serving as a healing abutment.
