The upper arch is called what?

Explanation:
The upper arch is the maxilla. In dental anatomy, arches refer to the rows of teeth housed in the jaws, and the maxilla is the fixed bone that forms the upper jaw and supports the upper teeth. The other terms don’t describe the upper jaw: the mandible is the lower jaw, the oral refers to the mouth in general, and occlusion is how teeth from the upper and lower arches come together. So the correct term for the upper arch is maxilla.
