The primary bones of the face are the mandible, maxilla, frontal bone, nasal bone, and the zygoma. The maxilla is one of the pairs of bones that make up the upper jaw; the bones that hold the upper teeth and also form part of the eye sockets, hard palate, and nasal cavity. It is also called the maxillary bone.read more
Each of the maxilla attaches laterally to the zygomatic bones of the face which make up the cheek bones. Each maxilla has four processes which are listed in the following description.

It also forms part of the eye sockets, roof of the mouth, and the lateral walls of the nasal cavity. The maxilla forms the upper jaw by fusing together the two irregularly shaped bones along the palatal fissure. The maxillary bones in each side join in the middle at the intermaxillary suture and helps to support the posterior teeth. The way these bones are positioned helps to support and relieve the heaviness of the skull and may also help to allow the voice to resound.
