Study Notes
Extra Oral Anatomical Landmarks
- Interpupillary line serves as a reference for maxillary denture alignment.
- Ala of the nose and tragus help determine horizontal plane orientation.
- Naso-labial sulcus and modiolus are important for facial aesthetics and denture fit.
- Philtrum and angle of the mouth influence denture contour and positioning.
- Labiomental sulcus and vermillion border aid in defining the denture's borders.
- Dr. Vibrating line marks the posterior limit of the maxillary denture, crucial for denture retention.
Labial Frenum
- Fibrous band, possibly single or multiple, located at the midline of the maxilla.
- Covered by mucous membrane, integral for denture retention.
- Vibrating line's position confirms the posterior limit for optimal denture performance.
Maxillary Denture Foundation
- Rugae area is classified as a secondary stress-bearing area, important for distributing occlusal forces.
- Phonetic function is influenced by denture design; particularly affects articulation of the letter "S."
- Rugae increases the surface area of the denture, enhancing retention and stability during function.
