The hard palate is the horizontal plate of bone crossing between the maxillary alveolar arch that separates the oral cavity from the nasal cavity. The maxilla forms the anterior two-thirds of this boney plate and the horizontal processes of the palatine bones form the posterior third of the hard palate. It is ensheathed in a dense, tough mucoperiosteum. The hard palate is supplied by the nasopalatine and posterior palatine vessels.
