Multi-unit Abutment: key to the All-on-4® treatment concept

by: Michael Stuart

It’s now fifteen years since we began producing our Multi-unit Abutment – a first for the industry at the time. Since then, this product has had a big impact on patient treatment. It started the trend for restoring multiple teeth using tilted implant placement that is now backed by a wealth of clinical evidence.

A decade and a half since the launch of our original Multi-unit Abutment, the concept is now being accepted as effective by the implant industry as a whole.1-28 Back when the first of the products were sold, our engineers could only have hoped that their small piece of technology would have such a profound effect on patient care. To this day, it is still the only one of its kind with a patented handle for a supreme handling experience. It’s also specifically designed for implants with regulatory clearance for immediate loading, and can be used in the treatment of both edentulous and partially edentulous patients.

Small, but perfectly formed

Since 2008 alone, we delivered 1.2 million Multi-unit Abutments. In that time, as a key enabler of the clinically and scientifically proven All-on-4® treatment concept, the Multi-unit Abutment has allowed thousands of edentulous and soon-to-be edentulous patients to benefit from a minimally invasive treatment process. It makes it possible to restore a full arch with a fixed restoration using just four implants, even when the bone is reduced.

The angled Multi-unit Abutments allow for the tilting of the two posterior implants, meaning longer implants can be positioned in the anterior bone, rather than in the posterior where the bone is often resorbed. This increases bone-to-implant contact and reduces the need for vertical bone augmentation. Anchoring the implants in better quality anterior bone also reduces cantilevers, improving support for the prostheses.1,2 Furthermore, tilting the implants helps avoid critical nerve structures and the maxillary sinus. All this makes it a less invasive, lower risk, and more cost efficient procedure for the patient, while increasing efficiency for the clinician.

An immediate solution for edentulism

Our implants offer primary stability at a level that allows for the restoration to be placed immediately. The TiUnite surface and patented grooves then help maintain this stability during osseointegration. In combination with our Multi-unit Abutments and the All-on-4® treatment concept, this allows edentulous and soon-to-be edentulous patients to leave the dental surgery with a full set of teeth and renewed self-confidence. Our philosophy is that patients should live every day to the fullest, and that the months of waiting for teeth in delayed loading protocols should be avoided if the indication allows. 

Our Multi-unit Abutments are also available for some third party implants, though it is important to note that not all implant systems provide the primary stability required for immediate loading protocols.

Multi-unit Abutment handle

Getting a handle on treatment success

Our Multi-unit Abutment comes with a unique handle. This makes the clinician’s life easier in a number of ways. A patented solution in its own right, available exclusively for our Multi-unit Abutments, the handle replaces the tweezers recommended by other implant suppliers for their angulated abutments. It makes holding, placing, and adjusting the abutment much simpler, improving the user experience while increasing safety and predictability.

Once the abutment is placed, the handle serves as a guide for checking that the angulation is exactly as required. It also supports clinicians using the NobelGuide protocol for prosthetic-driven treatment planning and guided implant surgery. Here, the handle becomes part of the jig in the retropositioning of the Multi-unit Abutment from the model into the patient’s mouth.

A framework for optimal esthetics

Our Multi-unit Abutments open the door to a complete individualized restorative portfolio through NobelProcera. A wide range of precision-milled and esthetically excellent restorative frameworks in both titanium and zirconia are available. It is estimated over 90,000 NobelProcera frameworks have been produced for our Multi-unit Abutments since 2008, each individualized to give a patient the new smile they deserve. 

Though only a small part of our All-on-4® treatment concept, the Multi-unit Abutment plays a very big role. Without it, this innovative and effective solution for edentulous and soon-to-be edentulous patients would not be possible. 

When used in combination with the All-on-4® treatment concept, the product’s incredible impact on treatment is evidenced by a multitude of studies e.g.3-28, each confirming the safety, performance, and longevity of the product with this protocol. Our Multi-unit Abutment is the supporting act that allows the All-on-4® treatment concept to play a starring role, both for patients and clinicians.
