The All-on-4 treatment involves placing only four dental implants - two in the front of each jaw and two tilted posteriorly at a 45 degree angle. This technique allows for fixed teeth to be placed even in patients with minimal bone volume, as the tilted posterior implants make use of available bone. Studies show a 98% success rate for All-on-4, and it provides patients with a permanent set of teeth similar to natural teeth, avoiding the need for removable dentures. The procedure is typically completed in one or two appointments, with temporary teeth placed immediately and permanent teeth in a follow up visit 6-8 months later.
