Study Notes
Posterior Palatal Seal
- The primary purpose of the posterior palatal seal is to provide retention and stability to the denture.
- The shape of the posterior palatal seal area is typically triangular or heart-shaped.
Lingual Frenum
- The lingual frenum is located under the tongue, near the floor of the mouth.
- A short lingual frenum can cause issues during denture construction, such as restricted tongue movement and speech difficulties.
Sublingual Gland Region
- The sublingual gland region affects the height of the flange in a denture by limiting its vertical extension.
- The sublingual gland region is associated with the anatomical landmark known as the sublingual fossa.
Alveololingual Sulcus
- The purpose of the alveololingual sulcus is to provide a barrier that prevents food and liquids from accumulating under the denture.
- The alveololingual sulcus marks the posterior limit of the denture to ensure a proper fit.
Denture Construction
- The posterior palatal seal area serves as a guide for positioning the border of the denture in the posterior palate.
- The alveololingual sulcus compensates for acrylic shrinkage and maintains palate contact with the denture base.
Clinical Considerations
- Overextension of the upper denture can cause patient discomfort, pain, and difficulty eating or speaking.
- The vibrating line is a crucial landmark during denture construction, and the area 2 mm anterior to it is significant in determining the proper border of the denture.
