Tongue plate design is often associated with the construction of oral prostheses, particularly in the design of mandibular prostheses. The main function of the tongue plate is to provide stability to the denture while reducing pressure on other tissues in the mouth. Key design points include:
- Position and size: The design of the lingual plate will be adapted to the patient's specific situation, such as the distance from the gingival margin to the lingual tie. The tongue plate needs to be a certain distance away from the gingival margin (e.g. 3-4mm) to avoid excessive pressure on the gingiva.
- Form: The form of the tongue plate is adjusted to the vertical, concave or sloping shape of the alveolar auditory canal to ensure proper contact with the mucosa or a certain distance away from it, thus preventing pressure and pain when the denture is functioning.
- Function: The tongue plate plays an important role in the stability and comfort of the denture, especially in preventing movement and rotation of the denture in the mouth.
