Until recently, the only option for replacing an entire arch of missing teeth was a removable prosthetic device known as dentures. Dentures are still available today (and many improvements have been made), but they still cause many problems for many patients. It is well known that traditional dentures are prone to slip out of place. In addition to being embarrassing, this can make speaking and eating hard, as well as rub your gums, which can cause sores. Dentures still require daily care. Furthermore, they require periodic replacement as your jawbone changes.
