An overdenture is a denture, the base of which covers one or more teeth, prepared roots or implants.

A patient who would rather not wait several months for the end result achieved by a palatal expander may be able to opt for a surgical separation of the maxilla.
Dentures can help people via: Mastication: chewing ability is improved by the replacement of edentulous (lacking teeth) areas with denture teeth.; Aesthetics: the presence of teeth gives a natural appearance to the face, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that results from the loss of teeth.
