What exactly is a All on 4 treatment?

Updated: Jul 19

The All On 4 ®️ treatment concept provides a permanent, screw-retained, same-day replacement for the entire upper and/or lower set of teeth. This procedure is best for patients with significant tooth loss, decay, or extreme bone loss, which prevents them from getting traditional dental implants protocols like All on 6 or All on 8. This option will eliminate the need for bone graft, will minimize the All On 4 Dental Implant cost, and will increase the comfort and stability. With the All on 4 procedure, you receive dental implants and a full set of non-removable dentures during a single appointment.

Why All On 4 ®?


The reasons the All On 4 Dental Implants technique has gained popularity are:


The high volume of edentulous patients with terminal dentition who can be treated with this technique

The better esthetics and the low cost for the patient compared to more traditional techniques (bone grafting, more implants, and multiple procedures)

The high success rate of the procedure

The ease and safety of the technology enables it to be performed more trustfully

Oftentimes patients will ask us what is All On 4 and how is it different from the conventional implant procedure?

All On 4 is a dental implant technique where the upper or lower set of teeth are replaced with just four implants. 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 the bone in order to secure the implant.


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.
