The procedure All-on-4™, consists in establishing a fully customized hybrid denture (a fixed permanent denture which resembles a bridge) based only on four titanium implants. These implants act as “pillars” to the bridge that supports the prosthetic teeth.
The posterior implants are substantially angled at approximately 45 degrees to avoid compromising the sinus cavity in the upper jaw and the nerve canal in the lower jaw.
With the All-on-4 Procedure, qualified patients receive just four implants and a full set of new replacement teeth in just one appointment—without bone grafts! The real appeal is how quickly permanent implants can be placed so that patients can leave the same day with fixed, non-removable replacement teeth.The four implants support a fixed prosthesis with 12 to 14 teeth and it is placed immediately on the day of surgery.
Traditional approaches to restoring a full arch of teeth usually involved bone grafts, six or more implants, and as many as 18 months of treatment. That meant that a patient often would be without any teeth, or with ill-fitting temporary dentures for more than a year.
With the All-on-4 Procedure, the patient has one consultation visit ,after which the patient is scheduled for surgery and the new teeth are fitted and adjusted, all in one appointment (even when extractions are necessary). The patient comes to the office in the morning with unhealthy (or no) teeth, and leaves in the afternoon with a beautiful set of fixed, functional teeth.
