The hard palate is a thin horizontal bony plate made up of two bones of the facial skeleton, located in the roof of the mouth. The bones are the palatine process of the maxilla and the horizontal plate of palatine bone. The hard palate spans the alveolar arch formed by the alveolar process that holds the upper teeth (when these are developed).
The two plates form the posterior part of the hard palate and the floor of the nasal cavity; anteriorly, they join with the maxillae. The two horizontal plates articulate with each other at the posterior part of the median palatine suture and more anteriorly with the maxillae at the transverse palatine suture. [3]
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla.It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest.
The palate (/ ˈ p æ l ɪ t /) is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity . [ 1 ] A similar structure is found in crocodilians , but in most other tetrapods , the oral and nasal cavities are not truly separated.
Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate. Extension of the lesion to the mucosa of the residual ridges have also been observed. 11% to 13.9% of patients who wear maxillary complete dentures with complete palatal coverage has been reported to have IPH.

A torus palatinus (pl.: tori palatini), or palatal torus (pl.: palatal tori), is a bony protrusion on the palate. Palatal tori are usually present on the midline of the hard palate. [1] Most palatal tori are less than 2 cm in diameter, but their size can change throughout life.
The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate representing the inferior termination of the incisive canal. [citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa. [1] The incisive foramen is situated immediately behind the incisor teeth, and in between the two premaxillae.
The oral mucosa has no muscularis mucosae, and clearly identifying the boundary between it and the underlying tissues is difficult. Typically, regions such as the cheeks, lips, and parts of the hard palate contain submucosa (a layer of loose fatty or glandular connective tissue containing the major blood vessels and nerves supplying the mucosa ...
