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 for only of a fraction of the cost the patient would typically pay with conventional implant dentistry involving bone grafts and sinus lifts.
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. Most of the patients who were told in the past that they cannot have dental implants because of not enough bone or without grafting, can have this procedure done because this allows the implants to be placed in a tilted position, thus making more bone available for the stabilization of the implant.
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. Actually having one or more tilted implants supporting a restoration is biomachanically more stable than straight, paralel implants. The same principle is used when the bridges and the roofs are build using oblique joists.
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.
Efficient treatment flow results in shorter treatment times and improved patient satisfaction. The whole procedure can be done in one day(including the extraction of unrestorable teeth.
