Multi-unit Abutment

Key to the All-on-4® treatment concept

Engineered with precision and simplicity in mind

The original Nobel Biocare Multi-unit Abutment was developed in 2000 and was a first for the industry at the time. Since then it has been accepted as an industry standard and many have tried to copy its innovative design. What sets the Multi-unit Abutment apart from the rest are the design details, which can make or break a restoration. 

The Multi-unit Abutment is carefully designed to accommodate both edentulous and partially edentulous arches, particularly when using the clinically and scientifically proven All-on-4® treatment concept.1-29

Carefully designed

  • Short cone for limited interocclusal space.
  • Wide shoulder for easy positioning of the prosthetic restoration.
  • For various soft tissue anatomies – both straight and angled (17° and 30°) variants are available in nine different collar heights.

Easy and secure handling

Each Multi-unit Abutment comes with a unique pre-mounted holder for simplified abutment seating. It also serves as a visual guide for checking correct abutment angulation.

Precision-engineered esthetics

Experience the incredible precision fit of NobelProcera fixed and fixed-removable restorations. You can choose from a variety of precision-milled CAD/CAM restorations, all designed and tested to fit on the Multi-unit Abutment. 

Multi-unit Abutment Plus

Take the All-on-4® treatment concept to the next level with the new Multi-unit Abutment Plus for conical connection implants. It is designed to provide an easy and fast temporization workflow.

Simplified temporization workflow

The Temporary Snap Coping easily snaps onto the Multi-unit Abutment Plus, eliminating the need for screw fixation during try-in and adjustment of the provisional prosthesis.

Reduced chair and lab time

The new snap functionality can substantially reduce the time needed for chairside denture conversion or creation of a new provisional restoration.

Authenticity matters

A system is only as strong as its weakest link. The performance of each specific component depends not only on the quality and design of the component itself, but also on its interface with the rest of the restorative system.

This is why we test and study both individual components—and how they work together—as well as the entire system that they constitute.

Testimonials

Dr. Rob Wain, United Kingdom

"I have been using Nobel Biocare Multi-unit Abutments for almost ten years. I use them routinely for All-on-4® treatment concept cases but also in multiple implant cases where I need to correct the angle before I can use a screw-retained prosthetic solution.

Working at tissue level is much more comfortable for the patient and convenient for me, allowing a more leisurely development of the final restoration. Long-term stability and success have been excellent, and the easy access for hygiene and maintenance simplifies ongoing care for the patient."

Dr. Peter Wöhrle, United States

"The snap function on the Multi-unit Abutment Plus allows for a quick, user-friendly incorporation of the temporary copings into the provisional restoration. This is significant as it saves valuable chair time and makes this a predictable procedure even for inexperienced clinicians“

Clinical cases

Dr. Alessandro Pozzi, Italy – All-on-4® treatment concept in the maxilla and the mandible

Situation: Female patient, 62 years old, edentulous maxillary and mandibular jaw.

Solution: All-on-4® treatment concept using NobelReplace Conical Connection implants with guided surgery. Final restoration with NobelProcera Hader Bar in the maxilla and NobelProcera Zirconia Implant Bridge in the mandible.

Dr. Rubén Davó, Spain – complete solution for severely resorbed maxilla and mandible

Situation: 60-year-old female with severe bone resorption of the upper and lower jaw with complete dentures.

Solution:  Brånemark System Zygoma and NobelReplace Tapered implants were used to rehabilitate the maxilla. For the mandible, the All-on-4® treatment concept was chosen. As a final prosthesis, fixed precision-milled NobelProcera Implant Bridges were chosen for both the maxilla and the mandible.

Dr. Paulo Maló, Portugal – All-on-4® treatment concept with NobelGuide

Situation: Totally edentulous female patient in her early 50s, rehabilitated with upper and lower removable dentures over 15 years prior.

Solution:  Fixed implant-supported bimaxillary rehabilitation using the All-on-4® treatment concept. The NobelGuide protocol (flapless) is followed in the maxilla and the conventional flap technique with the All-on-4® Guide is followed in the mandible. As a final prosthesis, fixed precision-milled NobelProcera Implant Bridges were chosen for both the maxilla and the mandible.
