All-on-4 – the efficient treatment concept with immediate loading

For all Nobel Biocare implant systems

Multi-unit Abutments are available for all Nobel Biocare implant systems.

High stability with only four implants

Angled posterior implants can be anchored in better quality anterior bone and offer improved support of the prosthesis by reducing cantilevers.


Widely documented implant for All-on-4. Slightly tapered with a more pronounced apical taper allowing for under preparation. Designed to achieve high primary stability in soft to medium bone and to shorten drilling protocols.

Preservation of vital structures

Angled posterior implants help avoid the mandibular nerve and the maxillary sinus.

Reduced need for vertical bone augmentation

Angled posterior implants allow for the use of longer implants, increasing bone-to-implant contact and reducing the need for bone grafting.

Wide variety of prosthetic options

Fixed provisional prosthesis for immediate loading. Fixed and removable solutions for final restorations.

With or without NobelGuide

Safe and minimally invasive surgery with full 3D diagnostics and planning using NobelGuide. Traditional open flap surgery using the All-on-4 Guide for accurate placement of implants.

The All-on-4 treatment concept was developed to provide edentulous patients with an efficient and effective restoration using only four implants to support an immediately loaded full-arch prosthesis.

The All-on-4 treatment concept offers clinicians and their patients various clear benefits:

Stability even in minimum bone volume

By tilting the two posterior implants, longer implants can be used in minimum bone volume, increasing bone-to-implant contact and reducing the need for vertical bone augmentation. The tilted posterior implants can be anchored in better quality anterior bone, reducing cantilevers and thus improving support of the prosthesis.

Good clinical results

Biomechanical measurements show that tilted implants, when part of prosthetic support, do not have a negative effect on the load distribution. The tilting of implants has been used in clinical practice for over a decade and has shown good results.

Planning with NobelGuide treatment concept

All-on-4 treatments can be planned and performed using the NobelGuide treatment concept, ensuring accurate diagnostics, planning and implant placement. The NobelGuide Software allows for detailed diagnostics such as identification of available bone, virtual implant placement according to the anatomical situation and prosthetic needs, and ordering of an individualized surgical template. NobelGuide supports minimally invasive flapless techniques as well as surgical access through mini-flaps and full flaps, while the surgical template ensures guided and therefore exact implant placement.


Prosthetic flexibility

With an All-on-4 treatment, patients benefit from an immediate implant-supported restoration, as a provisional prosthesis is screwed onto the implants right after surgery. Final solutions for All-on-4 treatments include both fixed prostheses, such as NobelProcera Implant Bridge Titanium with acrylic veneering, or individual NobelProcera crowns cemented to the bridge framework, and removable solutions, such as acrylic overdentures on a NobelProcera Implant Bar Overdenture.

Increased efficiency

Efficient treatment flow results in shorter treatment times and improved patient satisfaction.
