context_page_description: A removable partial denture is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge for any reason, such as a lack of required teeth to serve as support for a bridge or financial limitations.
  This type of prosthesis is referred to as a removable partial denture because patients can remove and reinsert it when required without professional help. Conversely, a "fixed" prosthesis can and should be removed only by a dental professional.
context_section_description:    Sublingual bar- A sublingual bar is similar to a lingual bar but is located on the floor of the mouth posteriorly and inferiorly to its usual location. They are used when the superior border of a lingual bar would be positioned too closely to the gingival border. They are contraindicated in patients with a high lingual frenum and in situations where they may interfere with tongue movements.
  Lingual Plate
     A lingual plate is a thin plate contoured to the lingual surfaces of the lower anterior teeth. A lingual plate is useful when there is insufficient space for a lingual bar which would result in irritation of the gingival boundary.
  If the teeth are spaced out and the patient does not wish for visible metal to be seen then an interrupted lingual plate may be used where the material is cut away where it would be visible anteriorly.
  A disadvantage of a lingual plate is that it covers a lot of gingival margins and is less hygienic than a lingual bar. It should be used with caution in those patients with a high caries rate. A major advantage is that is easier to add teeth to a denture with a lingual plate than a lingual bar connector. In addition, it is useful in providing some additional support for mobile lower anterior teeth.
