What are 3D Dental X-Rays and How Can They Help?

3D X-ray is a type of advanced medical imaging technology that provides a three-dimensional view of the human body or specific parts of it. It is often used in dental medicine to visualize the teeth, jawbones and surrounding facial structures.

This cutting-edge technology offers dental specialists a more complete and detailed view of the oral cavity and maxillofacial structure, giving them a better understanding of any dental conditions the patient has and enabling them to develop a more precise treatment plan.

In this article, our Montreal-based dentists explain the specifics of 3D dental X-rays and how these valuable tools can help specialists improve their patients’ oral health.

3D dental X-rays and their advantages over conventional x-rays

The advent of 3D dental X-ray technology, also known as cone beam, 3D scan or CT scan, has made diagnostic work much simpler for oral health specialists.

It allows dental structures to be viewed from 3 angles due to image processing algorithms that put together multiple 2D images taken from different angles.

This imaging technology is often used when planning orthodontic treatment to correct misaligned teeth. 3D X-rays can also help dental surgeons detect anomalies and plan surgical procedures with greater precision.

3D dental X-ray (cone beam) technology: a major advancement

3D dental X-ray is a cone-beam imaging technique that enables dentists to analyze dental and facial anatomy in three dimensions using computerized axial tomography.

3D X-rays are used in conjunction with visual examination when a dentist requires a more detailed view of the anatomy than traditional imaging can provide.

3D X-rays have many advantages over traditional dental imaging, including:

  1. A more complete picture of the patient’s oral anatomy: The ability to obtain a three-dimensional view of the teeth, bones and surrounding structures is a significant advantage when it comes to assessing bone density for dental implant placement.
  2. More accurate diagnostics: A 3D view provides better insight into any dental conditions the patient might have, leading to more accurate, timely diagnoses and a more effective treatment plan (e.g. identifying impacted teeth).
  3. More precise treatment planning: 3D dental X-rays enable dental surgeons to plan surgical procedures such as wisdom teeth removal with greater precision, reducing the risk of errors and postoperative complications.
  4. More accurate measurements for procedures such as denture and dental crown placement.
  5. Less radiation: 3D dental X-rays use significantly lower levels of radiation than traditional scanners, making them safer for patients.
  6. Earlier detection of anomalies: 3D X-rays can detect dental anomalies such as lesions and cysts earlier, improving the chances of successful treatment.

How do 3D dental X-rays work?

3D dental X-ray is cutting-edge medical imaging technology that uses three-dimensional images to visualize the structures of the mouth. It can show the teeth, jawbones, sinuses, nerves and temporomandibular joints in a single image.

The cone beam imaging process is done using a device called a dental CBCT (cone-beam computed tomography) machine. The patient is asked to stand in front of the machine and hold still while it takes almost 600 images in quick succession.

Projections rotate 360 degrees around the mouth to generate the images, which are then assembled and processed by modelling software to create a 3D view of the teeth.

3D dental X-rays at Clinique dentaire 1935 ensure patient comfort

3D dental X-ray is a new medical imaging technology that can be used to facilitate diagnostics, dental treatment planning and long-term oral health monitoring. It can help identify problems such as tumours, dental anomalies, periodontal disease and nerve damage.

3D dental X-rays are a valuable tool for dental health professionals because they provide a detailed view of the structures of the mouth. If you would like to meet with a dental specialist and benefit from high-quality care, don’t hesitate to contact the experts at our Montreal clinic.
