Introduction to Nobel All-on-4® Treatment
The All-on-4® treatment consists of four implants, two straight implants in the anterior and two angled implants in the posterior, which support a provisional, fixed, and immediately loaded full-arch prosthesis as a potentially graftless solution.
Patients who are considering the All-on-4® treatment usually have an edentulous (or toothless) mandible or maxilla and are considering or advised to have simultaneous extraction of their remaining teeth with implant placement and provisional restoration.
Rapid Improvement in Quality of Life
The All-on-4® treatment concept provides edentulous and soon-to-be edentulous patients with a fixed full-arch prosthesis on four implants on the day of surgery. This quickly leads to improved patient satisfaction – with regards to function, aesthetics, sense, speech, and self-esteem.
Shorter Treatment Times
Two key elements significantly reduce treatment complexity, the number of surgeries, and the overall treatment time: tilting of the posterior implants avoids the need for time-consuming bone grafting procedures, while immediate loading shortens time to teeth.
The All-on-4® treatment concept is not only the least time-consuming treatment option, but also the least costly in comparison with conventional implant treatment modalities of the edentulous and soon-to-be edentulous jaw.
Stability Even in Minimum Bone Volume
By tilting the two posterior implants, longer implants can be used. This increases bone-to-implant contact and avoids vertical bone augmentation. In addition, the tilted implants can be anchored in better quality anterior bone, reduce cantilevers and help avoid important anatomical structures.
