The anterior two-thirds of the hard palate is formed by the and the posterior-third of the hard palate is formed by the bones.

The anterior two-thirds of the hard palate is formed by the maxillae (maxillary bones), while the posterior third of the hard palate is formed by the palatine bones.

The maxillae are the two fused bones that make up the upper jaw and contain the upper teeth, and they play a significant role in forming the hard palate's anterior region. The palatine bones are a pair of L-shaped bones located at the back of the oral cavity that contribute to the hard palate's posterior region. These bones work together to create a bony partition between the oral cavity and the nasal cavity, which is crucial for effective speech and swallowing functions.
