Further back the maxilla is, the worse the face looks, as it elongates the face.

Size and shape of the nose is largely dependent on the position of maxilla

From the aesthetic point of view, further forward the maxilla is, the greater the level of facial beauty is

3. Memorize the following words you will need in this unit.

Orthodontists have never seen a maxilla that is too far forward, it doesn’t exists in today’s modern environment

Sometimes (e.g. in bony fish), the maxilla is called "upper maxilla," with the mandible being the "lower maxilla." Conversely, in birds the upper jaw is often called "upper mandible."

Reading

The Superior Maxillary Bones

The maxillae are large, irregularly shaped paired bones that form the upper jaw. They are fused in the middle at the intermaxillary suture. Above, they join with the frontal bones of the forehead and laterally with the zygomas, or cheekbones. Each assists in forming the boundaries of three cavities: the roof of the mouth, the floor and lateral wall of the nose and the floor of the orbit. They also enter into the formation of two fossae, the infratemporal and pterygopalatine, and two fissures, the inferior orbital and pterygomaxillary.

Each maxillary bone consists of a body and four processes: zygomatic, frontal, palatine, and alveolar ones. The frontal process articulates with the frontal bone. The zygomatic process articulates with the zygomatic bone. The palatine process forms the anterior three quarters of the hard palate. The alveolar process bears the teeth.

The body of maxillary bones is somewhat pyramidal in shape, and contains a large cavity, the maxillary sinus. This cavity falls on each side of the nose.

The body of each maxillary bones has four surfaces — an anterior, a posterior or infratemporal, a superior or orbital, and a medial or nasal ones.

The anterior surface presents from medial to lateral, the incisive fossa, the canine eminence and the canine fossa. The anterior surface near the infraorbital margin presents the infraorbital foramen which transmits the infraorbital nerve and vessels. Medially the anterior surface ends at the nasal notch. Lower border of the nasal notch in the median plane projects as the anterior nasal spine.

The medial surface presents the maxillary hiatus. In the living the maxillary hiatus is smaller in size due to the attachment of the surrounding bones. The medial surface of maxilla forms part of the lateral wall of nasal cavity. Anterior to the maxillary hiatus the medial surface presents the nasolacrimal canal which transmits the nasolacrimal duct.

The posterior surface of the maxilla shows few minute foraminae which transmit the posterior superior alveolar nerve and vessels, to the upper molar teeth. The medial part of the posterior surface forms the anterior wall of the pterygopalatine fossa. The entrance to the pterygopalatine fossa from the infratemporal fossa is called the pterygomaxillary fissure. The posterior end of the alveolar border is called the maxillary tuberosity.

The superior surface of the body of the maxilla forms the floor of the orbit. It is called the orbital surface. It represents the infraorbital groove and canal which lodges the infraorbital nerves and vessels.

The Mandible

Structure

The word mandible comes from the Latin word mandere, meaning to chew. The mandible is "U" shaped, stretching from one ear, down forming the chin, and then back up to the other ear. It is connected to the upper part of the skull by two jaw joints called the temporomandibular joints.

The mandible consists of a horizontal horseshoelike body with a flat ramus projecting upward at each end. The rami are divided into two processes: the mandibular condyle and a front coronoid process. The mandibular condyles unite with the mandibular tissues of the temporal bones, while the coronoid processes serve as attachments for the muscles used in chewing. Other large chewing muscles are attached on the side surfaces of the rami.

In the newborn babies mandible consists of 2 halves joined by fibrocartilarge which unite with each other by the end of the first year, forming the symphysis menti. The body of the mandible has two surfaces – outer and inner – and two borders – upper (alveolar) border and lower border (base of the mandible).

Outer surface of the body

The mental protuberance is the point of the chin. There is an oblique line running downwards and forwards from the anterior body of the ramus to the mental protuberance. The mental foramen lies below the oblique line at the level of the second premolar tooth. The mental nerve and vessels come out through mental foramen.

Inner surface of the body

At the inner surface of symphysis menti there are two pairs of genial tubercles – upper and lower genial tubercles. The mylohyoid line is roughly a mirror image of the oblique line on the outer surface. The groove that runs below the mylohyoid line is called the mylohyoid groove. It transmits the mylohyoid nerve and vessels. The mylohyoid line divides the inner surface of the mandible into sublingual fossa above and the submandibular fossa below.

The sublingual fossa lodges the sublingual salivary gland and submandibular fossa lodges the submandibular salivary gland.

Borders

On its upper border the body of mandible supports the row of teeth. The lower border of the mandible near its medial end presents the digastric fossa, which gives origin to the anterior belly of digastric muscle.

Functions

Mandible is the largest and strongest bone of the face. It forms the lower part of the face and serves for the reception of the lower teeth. Movement of the lower jaw opens and closes the mouth and also allows for the chewing of food. Four different muscles connect to the lower jaw to allow it to move. These muscles are the masseter, the temporalis, the medial pterygoid, and the lateral pterygoid.
