MAXILLA

The maxilla is the upper jawbone, which contains the upper teeth. It is connected to the rest of the skull at the temporal bones and forms part of the facial skeleton. The maxilla is a horseshoe-shaped bone that sits in front of the ethmoid bone and orbits (eye sockets). It articulates with the mandible (lower jawbone) at the temporomandibular joint (TMJ).

The maxilla has two main parts: the body and the palatine process. The body is the central part of the bone that contains the teeth sockets (alveoli). The palatine process is a plate of bone that extends backwards from the body. It articulates with the palatine bones to form the hard palate.

The maxilla has four main processes: the frontal process, the zygomatic process, the alveolar process, and the palatine process. The frontal process forms part of the orbit (eye socket) and articulates with the frontal bone. The zygomatic process articulates with the zygomatic bone to form the zygomatic arch. The alveolar process contains the teeth sockets (alveoli) and supports the upper teeth. The palatine process forms part of the hard palate and articulates with the palatine bones.

The maxilla is an important bone in dental terms because it supports the upper teeth. It also helps to form the shape of the face and contributes to the airway. The maxilla is a complex bone that has many foramina (openings) and processes (bumps and ridges). These features provide attachment points for muscles, ligaments, and other tissues.
