* Maxilla: This is the larger bone, forming the majority of the hard palate. It contributes the palatine process, which forms the front two-thirds of the hard palate.
* Palatine Bone: This smaller bone contributes the horizontal plate, which joins the palatine process of the maxilla to form the back third of the hard palate.
So, while the hard palate is a single structure, it is formed by the palatine processes of the maxilla and the horizontal plates of the palatine bones.
