Anatomy of the Bones Inside the Mouth

The bones inside the mouth, also known as the maxilla and mandible, form the foundation of the facial structure and support the teeth. The maxilla, or upper jaw, is a large bone that forms the upper part of the mouth and the roof of the mouth. The mandible, or lower jaw, is the largest and strongest bone in the face, providing support for the lower teeth and muscles involved in chewing and speaking.

Maxilla

The maxilla is a paired bone that fuses in the midline to form the upper jaw. It consists of several parts, including:

The body of the maxilla, which forms the upper jaw and supports the upper teeth.
The alveolar process, which contains the sockets for the upper teeth.
The palatine process, which forms the anterior two-thirds of the hard palate.
The frontal process, which articulates with the frontal bone to form the nasal cavity.
The zygomatic process, which articulates with the zygomatic bone to form the cheek.

Mandible

The mandible is a single bone that forms the lower jaw. It consists of several parts, including:

The body of the mandible, which forms the horizontal part of the lower jaw and supports the lower teeth.
The ramus, which is the vertical part of the mandible that extends upward to form the temporomandibular joint.
The coronoid process, which is a triangular projection on the anterior surface of the ramus.
The condylar process, which articulates with the temporal bone to form the temporomandibular joint.
The mental foramen, which is an opening on the lateral surface of the mandible that transmits the mental nerve and vessels.
