  1. Chapter 29 Normal Anatomy: Panoramic Images

  2. Dental Radiography • Questions • What are normal anatomic features of panoramic images? • What bony landmarks of the maxilla and mandible and surrounding structures may be seen on panoramic images? • What soft tissue images may be seen on panoramic images?

  3. Dental Radiography • Chapter 29 Reading • Iannucci & Howerton (pp. 357-367)

  4. Dental Radiography • Chapter 29 Outline • Normal Anatomy: Panoramic Images • Normal anatomic landmarks • Air spaces seen on panoramic images • Soft tissues seen on panoramic images

  5. Introduction • Iannucci & Howerton (pp. 357-358) • Purpose • To review the normal anatomy of the maxilla and mandible as viewed on a panoramic image • To examine air space images and soft tissue images

  6. Normal Anatomic Landmarks • Iannucci & Howerton (p. 358) • Bony Landmarks of Maxilla and Surrounding Structures • Bony Landmarks of Mandible and Surrounding Structures • Air Spaces Seen on Panoramic Images • Soft Tissues Seen on Panoramic Images

  7. Bony Landmarks of the Maxilla and Surrounding Structures • Iannucci & Howerton (p. 358) (Fig. 29-1) • Mastoid process • Styloid process • External auditory meatus • Glenoidfossa • Articular eminence • Lateral pterygoid plate • Pterygomaxillary fissure • Maxillary tuberosity • Infraorbital foramen • Orbit
