For patients who are missing most or all of their teeth, the All-on-4 option is the perfect way to create a full set of beautiful, functional teeth. This procedure is similar to single dental implants in that it involves the use of surgical-grade titanium posts. The difference is four-to-six posts are used, strategically placed throughout the upper or lower arch. A metal bar spans across the posts and provides the attachment point for a set of custom-made teeth. These prosthetic teeth are much stronger than dentures, allowing patients to enjoy all the foods they did with their natural teeth. All-on-4 dental implants are considered permanent restorations because they can only be removed by dentists.
