There are three types of dentures: full (complete), fixed and removable partial dentures. The former is only required in people who have lost all or most of the teeth on either of the two arches of the mouth (maxillary – top and mandibular – bottom). Most patients missing only a few teeth opt for fixed partial dentures, also known as “crown and bridge.” These must be precisely installed, especially when in between healthy teeth. Removable partial dentures are different from fixed partial dentures in that they are normally only used by people who cannot have fixed dentures or have lost too many teeth for fixed dentures, but too few for full dentures. A frequent issue with dentures is their ability to remain in place during usage.
