The all-on-4 option is a popular choice for patients who have complete dentures but want a more reliable option that functions much better. This process requires the oral surgeon to place four dental implants along the ridge of the dental arch and use them to support a more conservative full denture that snaps in place. The all-on-4 process eliminates the need for removable complete dentures and provides full functionality for patients. It also helps maintain the jaw's natural bone, unlike traditional full dentures, resulting in a sunken-in appearance due to bone resorption.
