A lingual plate is a type of mandibular major connector that is used in a removable partial denture in the field of dentistry.

Once fabricated, adding teeth to this type of major connector is easier than the ...
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.
A removable partial denture (RPD) 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 (a fixed partial denture) for any reason, such as a lack of required teeth to serve as support for a bridge (i.e. distal abutments) or financial limitations.
Lingualized occlusion is defined as a form of denture occlusion that articulates the maxillary lingual cusps with the mandibular occlusal surfaces in centric, working, and non-working mandibular positions. [1] The concept of lingualized occlusion was again influenced by Gysi, when he designed a crossbite posterior teeth model concept. [8]
A cingulum is a convexity mesiodistally resembling a girdle, encircling the lingual surface at the cervical third, found on the lingual surface of anterior teeth. It is frequently identifiable as an inverted V-shaped ridge, [ 10 ] and its appearance is comparable to a girdle. [ 11 ]
Most commonly, the extra cusp is located on the lingual surface, giving a three-pronged appearance. [5] Rarely, however, the extra cusp may be situated on the facial surface, or there may be extra cusps on both lingual and facial surfaces. [5] There may be a deep groove between the talon cusp and the rest of the tooth.

Note the lingual buttons extending, in the photo, upward on #2 (on the left) and downward on #4. These are used to grasp the crowns with a hemostat and make them easier to handle. They can also be used to aid in removal of the crown in case there is an excessive amount of retention during the try-in.
