All On 4 ist eine Zahnimplantattechnik, bei der die obere oder untere Zahnreihe durch nur vier Implantate ersetzt wird.

These four Implants act as a support mechanism for the placement of a new set of fixed teeth.

With the All On 4 dental implant procedure, the posterior implants are tilted 45° towards the rear of the mouth and placed into the anterior maxilla, a region of the jaw with higher bone density. Compared to other implant methods, the All On 4 technique doesn’t require the same density of bone to secure the implant.

Conventional Dental Implants Vs. All On Four

The dental implant itself is a small titanium screw that is positioned into the jawbone and then supports either a single tooth or a bridge of teeth. The titanium implant forms the foundation by which the replacement teeth are attached.

For the conventional dental implant procedure, a full arch rehabilitation required 6-8 implants to support a full fixed bridge.

Conversely, with just two implants positioned at the front of the mouth and two angled implants positioned at the back, only four implants are needed to provide support for the full arch.

The main limitation of the conventional full-arch teeth replacement method arises when screwing the posterior implants into areas of reduced bone density. The introduction of the 45° angulated implant meant that bone-deficient areas of the jaw could be avoided.

The less invasive nature of the All On 4™ also means the healing and rehabilitation process is considerably shorter, and since fewer implant fixtures are used, there is more flexibility to design and fit the optimum replacement teeth.

Oral Bone Health Issues

The All On 4™ technique has given patients with oral bone health issues, a better choice. In the past, a lack of upper jaw bone (frequently caused by sinus issues or bone loss) was a big problem for implant candidates and often required bone grafting to build the jaw up enough to support the 6-8 implants the old methods required.

But the All On 4™ technique has made a huge difference. And this is great news for patients with Osteoporosis or a lack of jaw bone.

Patients suffering from Osteoporosis, often think that they’re not candidates for dental implants due to their poor quality of bone. And in the past, that was true. But because All On 4™ eliminates the need for bone grafting, patients suffering from osteoporosis are usually able to have the All on 4 procedure.

The same is true for patients who have severely resorbed upper jaws. Zygomatic implants are a great option. These longer implants anchor to the underside of the cheekbones through the sinus space, bypassing the need to rely on the jaw bone as the sole source of support.

These innovative options can typically circumvent the need for invasive bone grafting procedures altogether.
