Dynamic dental x-rays are the latest technology for diagnosing jaw problems

In modern dentistry, diagnosis no longer relies solely on static images that capture the bony structures of the teeth and jaws. New technologies have emerged that reveal the functional movement of the temporomandibular joint (TMJ) and lower jaw during natural activities such as chewing, yawning, or opening and closing the mouth. One of the most advanced techniques featured at Dalili Medical is functional or dynamic dental imaging, which has revolutionized the understanding of TMJ disorders and jaw dysfunctions, helping in the development of more precise and effective treatment plans.

What is Functional or Dynamic Dental Imaging?
Functional or dynamic dental imaging is an advanced diagnostic technique that records the movement of the jaw and the temporomandibular joint (TMJ) in real time, rather than capturing only a static position. This technology allows the dentist to observe the sequence of motion and analyze any deviations, restrictions, or sounds associated with jaw movement.

How Functional Dental Imaging Works

The working mechanism varies depending on the technology used, but all techniques share some essential steps:

1. Patient Preparation: The patient is asked to sit or stand in front of the imaging device.

2. Movement Selection: Determining the range of motion to be evaluated, such as mouth opening, closing, or chewing.

3. Sequential or Video Imaging: Capturing a series of images or a short video of the movement.

4. Data Analysis: Using advanced computer software to convert the images into a 2D or 3D animated model.

Types of Functional or Dynamic Dental Imaging

• Dynamic Magnetic Resonance Imaging (Dynamic MRI):
  Uses safe magnetic waves to visualize the movement of soft tissues and the joint during motion.
  Ideal for evaluating the TMJ’s articular disc.

• Fluoroscopy:
  Uses X-rays to produce real-time moving images.
  Delivers lower radiation doses compared to conventional medical CT scans.

• Cine MRI:
  An advanced MRI technique that produces video-like sequences of jaw movement.

• Dynamic Cone Beam Computed Tomography (Dynamic CBCT):
  Provides high-resolution images of bone structures during movement.
  Useful for assessing joint mechanics.

• Video-Based Jaw Tracking:
  A digital system that uses sensors and cameras to record jaw movement with high precision.

Advantages of Functional Dental Imaging

• Accurate diagnosis of TMJ disorders.

• Comprehensive multi-angle visualization of jaw motion.

• Ideal treatment planning before surgery or orthodontic procedures.

• Post-surgical or post-orthodontic treatment assessment.

• Reduced diagnostic errors compared to static images.

Medical Uses of Functional Dental Imaging

• Diagnosing TMJ Disorders:

  • Identifying the cause of pain or clicking sounds.

  • Evaluating the degree of articular disc displacement.

• Surgical or Orthodontic Planning:

  • Studying jaw movement before surgery.

  • Assessing the mechanical impact of any planned adjustments.

• Treatment and Rehabilitation Monitoring:

  • Evaluating movement improvement after physical therapy or surgery.

• Diagnosing Malocclusion Issues:

  • Analyzing how the teeth meet during motion.

Steps in Functional Dental Imaging

1. Initial Examination: Reviewing medical history and physically examining the mouth and TMJ.

2. Patient Preparation: Removing any metallic objects or jewelry.

3. Imaging Process: Selecting the appropriate technique based on the clinical requirement.

4. Result Analysis: Reviewing the images or videos to develop a treatment plan.

Risks and Precautions

Although functional dental imaging is generally safe, certain considerations should be kept in mind:

• Some techniques (such as Fluoroscopy or CBCT) involve radiation exposure, which should be minimized.

• Avoid X-ray or CBCT imaging for pregnant women unless absolutely necessary.

• Ensure the chosen technique suits the patient’s condition.

How to Minimize Risks

• Use modern equipment with low radiation doses.

• Limit imaging to the minimum number of required captures.

• Strictly follow radiation protection guidelines.

The Future of Functional Dental Imaging

The future is moving towards integrating artificial intelligence (AI) into these techniques to automatically and accurately analyze jaw movement, detect problems within seconds, and further reduce radiation exposure to near-zero levels.

Conclusion

Functional or dynamic dental imaging represents a major advancement in diagnosing and treating TMJ and jaw-related problems. It provides a true dynamic view of movement, helping dentists create tailored treatment plans that improve patient comfort and increase treatment success rates.
