Study Notes
Anatomical Landmarks of the Lip and Face
- The philtrum is a midline shallow depression of the upper lip, starting at the labial tubercle and ending at the nose.
- The labial tubercle is a little swelling in the midportion of the vermillion border of the upper lip.
- The vermillion border is a transitional zone between the skin and the mucous membrane of the upper and lower lips, marked by a zone of thinner epithelium.
- The nasolabial groove is a furrow of variable depth that extends from the wing of the nose to some distance from the corner of the mouth.
Importance of Anatomical Features in Denture Fabrication
- Denture bearing areas are important for fabricating a complete denture with maximum retention, support, and stability.
- During extra-oral examination, the following anatomical features should be noted: vermillion border, nasolabial groove, philtrum, and labial tubercle.
True or False Statements
- The vermillion border is a pink or red zone of thinner epithelium marking the transitional area between the skin and the mucous membrane of the upper and lower lips. (TRUE)
- The nasolabial groove extends from the ala of the nose to the corner of the mouth. (FALSE - it ends at some distance from the corner of the mouth)
- The labial tubercle is a shallow depression of the upper lip that ends at the nose. (FALSE - the philtrum is a shallow depression that ends at the nose, not the labial tubercle)
