Basic intraoral anatomy: head, neck, and face. Explain the anatomy of the maxilla and mandible, including their structures and appearances on radiographs.
Understand the Problem
The text provides detailed information about the anatomy of the maxilla, mandible, and intraoral structures relevant to dental radiography. It describes various anatomical features, their locations, appearances on radiographs, and their significance.
Answer
The maxilla and mandible are crucial for facial structure, forming the upper and lower jaws respectively, visible on radiographs.
The maxilla is the central bone of the midface supporting the viscerocranium and forming the upper jaw, nose, and palate. The mandible is the largest skull bone, forming the lower jaw. Both are integral to facial structure, with distinct appearances on radiographs.
Answer for screen readers
The maxilla is the central bone of the midface supporting the viscerocranium and forming the upper jaw, nose, and palate. The mandible is the largest skull bone, forming the lower jaw. Both are integral to facial structure, with distinct appearances on radiographs.
More Information
On radiographs, the maxilla appears as symmetrical bones forming the middle third of the face, while the mandible is seen as a large, curved structure composing the lower jaw.
Tips
Confusing the location and function of maxilla and mandible is common. The maxilla is upper and supports the midface, while the mandible is lower and forms the jawline.
