All-On-Four/ All-On-Six

The All-on-Four concept was developed by Dr. Paulo Malo of Portugal in an effort to provide fully edentulous patients with the benefits of a fixed, full arch prosthesis at reasonable cost, without having to undergo additional grafting procedures.

For the dental procedure four small titanium implants are placed on the jaw line. Two dental implants are placed near the front of your jaw; another two implants are placed at a 45 ° near to the back of the jaw. The angulations enable the implants to reap greater support from the jawbone while, avoiding damage to vital oral structure and working like anchors for the permanent prosthesis.


Dr. Willardsen coined the term All-on-Six, to provide more stability with 6 implants rather than four. The introduction of 3-dimensional CT surgical planning software makes this approach even more valuable as now we can plan for best implant placement without additional grafting procedures, and fabricate the prosthesis prior to implant placement. When you arrive for implant installation, we insert the implants and the prosthesis within a very short period of time, usually less than one hour. Because we used minimally invasive surgery, recovery time and swelling is minimal.

Besides ensuring that your implants are permanently fixed in place, both procedures ensure a bone fusion between the implants and the bone, this bone fusion has the benefit of preventing future bone loss in the jaw. Helping to maintain a more youthful facial structure.
