Study Notes
Stress Relief Areas
- Areas unsuitable for stress absorption due to anatomy or underlying vital structures.
- Include specific anatomical features to better protect the underlying tissues.
Border or Limiting Structures
- Labial frenum: tissue fold that restricts movements of the lip.
- Labial vestibule: space between the inner lip and alveolar ridge.
- Buccal frenum: tissue fold that limits the movement of the cheek.
- Buccal vestibule: area between the inner cheek and teeth/gums.
- Hamular notch: notched area between the maxilla and the pterygoid hamulus.
- Posterior Palatal Seal Area: butterfly-shaped zone rather than a line, provides flexibility and stability for dentures.
Incisive Papilla
- A fibrous tissue pad over the incisive foramen at the end of the nasopalatine canal.
- Contains nasopalatine nerves and vessels, crucial for sensation.
- Provides relief to prevent rocking of dentures, reducing the risk of midline fractures.
Mid Palatine Raphe
- A fibrous seam running along the midline of the palate, important for structural integrity.
Torus Palatinus
- A bony overgrowth located at the midline of the palate, often covered by a thin mucous membrane.
- Considered a common anatomical variation that may affect denture fitting.
