Radiographic assessment of mandible fractures involves the use of various imaging techniques to visualize and evaluate the extent of the fracture. The most commonly used imaging modalities for assessing mandible fractures include:
1. X-rays: X-rays are often the first imaging modality used to assess mandible fractures. They can provide detailed images of the bones and help identify the location and extent of the fracture. Different views, such as panoramic, lateral oblique, and posteroanterior views, may be taken to get a comprehensive assessment of the fracture.
2. Computed tomography (CT) scan: CT scans provide detailed cross-sectional images of the mandible, allowing for a more precise evaluation of the fracture. CT scans are particularly useful for assessing complex fractures, displaced fractures, and fractures involving multiple segments of the mandible.
3. Cone beam computed tomography (CBCT): CBCT is a specialized type of CT scan that provides high-resolution 3D images of the mandible. CBCT is often used for assessing mandible fractures in dental and maxillofacial surgery settings, as it allows for detailed visualization of the fracture and surrounding structures.
4. Magnetic resonance imaging (MRI): MRI may be used in certain cases to assess mandible fractures, particularly when soft tissue injuries or complications are suspected. MRI can provide detailed images of the soft tissues, such as muscles, ligaments, and nerves, and help identify any associated injuries.
Overall, radiographic assessment of mandible fractures plays a crucial role in determining the appropriate treatment plan for the patient. It helps in accurately diagnosing the fracture, assessing its severity, and planning for surgical or non-surgical management.

Radiographic Assessment of Mandible Fractures
Panoramic Radiograph (Orthopantomogram)
- Best initial screening test for most mandibular fractures.
- Provides a wide and panoramic view of the entire mandible.
- Useful for detecting fractures in the body, angles, rami, and condyles.
Extraoral Facial Film
- Waters' View: Taken with the patient's head tilted 37° backward, facing the x-ray tube.
- Evaluates the anterior and posterior regions of the mandible, including the symphysis, parasymphysis, and body.
- Towne's View: Taken with the patient's head titled 40° forward, facing upward.
- Visualizes the anterior and posterior regions of the mandible, particularly the condyles, ramus, and angles.
Intraoral Films
- Bitewing Radiographs: Provides detailed views of the alveolar bone and teeth.
- Can detect fractures involving the alveolar process and mandibular teeth.
- Occlusal Radiographs: Taken with the occlusal film placed on the palate.
- Useful for visualizing fractures in the posterior mandible, such as the condyle and ramus.
Computed Tomography (CT)
- High-resolution imaging modality that provides detailed cross-sectional views.
- Used to assess complex or displaced fractures, particularly in the condylar and ramus regions.
- Can accurately evaluate intra-articular fractures and the presence of bone fragments or foreign bodies.
Magnetic Resonance Imaging (MRI)
- Rarely used to assess mandible fractures.
- May be beneficial in cases of soft tissue injury, joint effusions, or suspected non-displaced fractures.
Interpretation
- Assess the location and type of fracture (e.g., simple, comminuted, displaced).
- Evaluate the proximity of the fracture to vital structures (e.g., inferior alveolar nerve, mandibular canal).
- Determine the presence of bone fragments or foreign bodies.
- Assess the integrity of the temporomandibular joint.
