Short Description
The upper jawbone that holds the upper teeth, supports the face, and connects to the skull, playing a vital role in chewing and speaking.
Long Description
The maxilla is the upper jawbone that forms the central structure of the face, housing the upper teeth and playing a key role in chewing, speaking, and facial aesthetics. It is a paired bone that fuses at the midline and connects to the skull, forming part of the nasal cavity and eye sockets.
Unlike the mandible, the maxilla is a fixed bone, meaning it does not move independently. It provides structural support for facial features and influences dental occlusion (the way the upper and lower teeth fit together). Developmental abnormalities, trauma, or missing teeth can affect maxillary function and may require orthodontic or surgical intervention.
Common issues affecting the maxilla include maxillary fractures, improper jaw growth, and bite misalignment. Orthodontic treatments such as expanders, braces, and, in severe cases, orthognathic (jaw) surgery can correct maxillary irregularities. Maintaining oral health and seeking early dental evaluations help preserve maxillary function and facial harmony.
