Information about Anterior Surface Of The Body Of The Maxilla

Bone: Anterior surface of the body of the maxilla
Left maxilla. Outer surface.
Latinfacies anterior corporis maxillae
subject #38 158
Dorlands/Elsevier f_01/12351215
The anterior surface is directed forward and lateralward. It presents at its lower part a series of eminences corresponding to the positions of the roots of the teeth. Just above those of the incisor teeth is a depression, the incisive fossa, which gives origin to the Depressor alae nasi; to the alveolar border below the fossa is attached a slip of the Orbicularis oris; above and a little lateral to it, the Nasalis arises.

Lateral to the incisive fossa is another depression, the canine fossa; it is larger and deeper than the incisive fossa, and is separated from it by a vertical ridge, the canine eminence, corresponding to the socket of the canine tooth; the canine fossa gives origin to the levator anguli oris (aka Caninus).

Above the fossa is the infraorbital foramen, the end of the infraorbital canal; it transmits the infraorbital vessels and nerve.

Above the foramen is the margin of the orbit, which affords attachment to part of the Quadratus labii superioris.

Medially, the anterior surface is limited by a deep concavity, the nasal notch, the margin of which gives attachment to the Dilatator naris posterior and ends below in a pointed process, which with its fellow of the opposite side forms the anterior nasal spine.
