All-on-4 implant dentures are fixed implant dentures that are held in place with only four implants: Two axial anterior implants and two implants tilted up to 45 degrees in the posterior. The treatment concept is a cost-efficient, graftless solution that provides patients with a fixed full-arch prosthesis on the day of surgery.
Dentures are custom-made appliances that are used to replace missing or lost teeth to improve appearance and restore oral function such as speaking, smiling, and eating. They consist of a denture base and prosthetic teeth, which are made of high strength acrylic plastic resin, customized to fit the form and structure of the patient. There are two main types of dentures, traditional dentures, and implant dentures.
