Multi-unit Abutments: 
Key to the All-on-4®
treatment concept

Unlock the key to predictable full-arch restorations with Multi-unit Abutments

With nearly 25 years of clinical documentation, Nobel Biocare Multi-unit Abutments enable a simplified temporization workflow, reduced chair time, and allow clinicians to perform their best work.

Answering a clinical need

Nobel Biocare Multi-unit Abutments enabled the restoration of teeth using tilted implant placement. Developed in 2000, they were the first of their kind. They are now widely accepted as an industry standard.

Precision engineering

What sets the Multi-unit Abutment apart from the rest are the design details, which can make or break a restoration.2

Nobel Biocare continues to set the standard in patient care

Introducing the snap function in 2016 simplified the temporization workflow. It also reduced the chair and lab time, while fatigue strength increased by 25%.2

Backed by 20+ years of evidence

The clinical predictability of Nobel Biocare’s Multi-unit Abutments has been documented in at least 125 clinical studies.2

“Anatomical conditions often prevent placement of dental implants in a perfectly parallel orientation. This, together with the variable depth of implant placement and differences in soft tissue thickness, can make it difficult to verify the tightness of the connection between the screw-retained prosthetic restoration and the implant at the implant level. The resulting micro-gaps can cause inflammation and lead to excessive marginal bone loss. But the use of Multi-unit Abutments transfers the connection with the screw-retained prosthetic restoration above the soft tissues.

Based on my experience, the use of Nobel Biocare Multi-unit Abutments can significantly decrease the occurrence of peri-implantitis. Additionally, it enhances patient comfort during prosthetic appointments, as the delicate soft tissues created around the abutment stay untouched. I believe the use of Multi-unit Abutments should be a standard for implant-supported restorations on three or more implants.”
