The upper arch is called the ___.

Explanation:
The upper dental arch is formed by the maxilla, the upper jawbone that holds the upper teeth in its alveolar process. It also helps form the hard palate and parts of the nasal and orbital regions. The mandible is the lower jaw, the palate is the roof of the mouth (made by the maxilla and palatine bones), and the zygomatic bone is the cheekbone. So the upper arch is the maxilla.
