The lingual plate design in dentures is a design that enhances retention, which usually extends from the lingual side onto the palatal or lingual eminence in a wavy pattern. This design has important applications in prosthodontics, especially when enhanced denture stability and comfort are required.
The main purpose of the lingual plate design is:
Enhance denture retention and prevent denture movement in the mouth.
Improve denture comfort and reduce irritation to the patient's oral soft tissues.
Suitable for specific oral conditions such as shallow base of the mouth, high soft tissue attachment on the lingual side and significant lingual bulge.
