What is an All-on-4 ? All-on-4 treatment on Advanced Dental Care of Stafford provides patients with a fixed full-arch prosthesis that closely resembles the full function and appearance of natural teeth. All-on-4 treatment is a cost-efficient, graft less solution for people who have many missing teeth and that want a permanent alternative to removable standard dentures. The prosthesis is anchored to the bone with 4 dental implants. These specially designed implants typically do not require bone grafting, allowing for quicker recovery time. In addition, All-on-4’s tend to be more durable and last longer than standard dentures.
