Study Notes
Dental Imaging
- A panoramic image allows the dental professional to view large areas of the mandible and the maxilla on one projection.
Anatomical Structures
- The mastoid process is a bony prominence located behind the ear canal.
- The styloid process is a narrow and pointed bony projection located in the temporal bone.
- The palate bone separates the nasal cavity from the oral cavity.
- The maxillary sinuses are located in the maxilla bones.
Bone Articulations
- The zygomatic process of the maxilla articulates with the zygomatic bone.
Anatomy of the Palate
- The hamulus is located on the medial pterygoid plate of the sphenoid bone.
- The palatoglossal air space is located between the soft palate and the tongue.
Dental Imaging Techniques
- A panoramic imaging technique can show the angle of the mandible.
Air Spaces
- The glossopharyngeal air space appears as a radiolucent area on an image.
- The soft palate and the uvula function together to separate the nasal and oral cavities during swallowing.
Temporomandibular Joint
- The glenoid fossa is a depression in the temporal bone that forms the socket of the temporomandibular joint.
Maxillary Anatomy
- The maxillary tuberosity is a bony projection located on the posterior part of the maxilla.
- The infraorbital foramen is an opening located below the orbit that transmits the infraorbital nerve and vessels.
Mandible Anatomy
- The incisive foramen is located in the anterior part of the palate, and transmits the nasopalatine nerve and vessels.
- The mental foramen is located on the buccal surface of the mandible, and transmits the mental nerve and vessels.
- The mental ridge is a bony prominence located on the buccal surface of the mandible.
- The genial tubercles are two bony projections located on the lingual surface of the mandible, and serve as attachment points for the genioglossus muscle.
- The mylohyoid ridge is located on the lingual surface of the mandible, and serves as an attachment point for the mylohyoid muscle.
