The “All-on-6” procedure is designed as a permanent solution for the complete replacement of failing or missing teeth in the upper and/or lower jaws. This procedure uses 6 (or more) implants instead of similar procedures utilizing only 4 implants (“All-on-4”).
In our experience, there are many patients for whom a bridge by 6 (or more) implants is better suited and has a better long-term prognosis than a bridge that is supported by 4 implants. For example, patients with a heavier bite or who want to chew tougher foods, who have a larger jaw (greater distance between implants), or who have clenching or grinding habits usually require additional implants and a stronger final restoration.
In cases like this, we will often recommend an “All-on-6” solution and a sturdier final bridge (Zirconia instead of the typical Acyrlic)
