Labial frenum: single band of fibrous Connective Tissue. Creates labial notch when activated.Usually narrow due to mostly vertical action.

Labial vestibule: between the right and left buccal freni. Major muscle of lip in this area is orbicularis oris.

Buccal frenum: creates buccal notch, which is usually wider than labial notch because more clearance is needed for muscle activity in this area.

Buccal vestibule: extends from buccal frenum to hamular notch. It’s influenced mainly by the buccinator, modiolus & coronoid process.

Hamular notch: also known as pteryomaxillary notch. *Identifies distal end of maxillary denture.

Incisive papilla: a pad of fibrous CT overlying bony exit of nasopalatine blood vessels and nerves. It should not be compressed or displaced during impression making. Denture pressure on this can cause paresthesia or pain.

Anterior alveolar ridge and rugae: secondary support area because more susceptible to resorption.

Midline palatine suture: junctions of palatine processes and covered with a thin layer of mucosa.

Palatine aponeurosis: a tendon-like band in the midline which attaches to the posterior nasal spine and supports the palatal muscle.

Fovea palatini: two small indentations located on each side of the midline--- usually on the distal end of the hard palate. Usually used to determine the posterior border of the denture.
