PROCESS OF THE MAXILLA

The maxillary body emerge four major processes; the palatine process, zygomatic and alveolar we have already described and frontal process (ascending process). The frontal process is a bony plate, with two faces, lateral and medial, which continues superiorly to the edge maxillary anterior up to the frontal bone. The side face is covered by a vertical ridge, anterior lacrimal crest, which extends up the ridge orbital. The ridge divides this face on a part above, arranged under the skin, and a rear portion, orbital. In the latter is a groove which is continuous below the nasolacrimal duct. The medial part of the outer wall nostrils and presents a small transverse ridge where the front end of the articulated means turbinate ethmoid (ethmoid crest) and lower other similar (crest conchal) for the inferior turbinate. Bordes. By its forward edge the frontal process articulates with the nasal bone. The trailing edge (edge ​​tear) It articulates with the lacrimal bone. The upper edge is articulated the nasal edge of the front.
