With newer equipment and sophisticated software support, three-dimensional (3D) technology has advanced over the past 20 years. Diagnosis, treatment, planning, and medical education are possible using applications designed for clinical settings. Orthodontics also uses 3D technology to capture accurate details of a patient’s anatomical structures, after which dentists and orthodontists can offer an individualized care plan.

How Does 3D Imagery Work?

Three-dimensional imaging is an imaging technique that uses 2D data to simulate a 3D scene. 

The standard 3D imaging techniques in orthodontics include: 

  • Computerized Tomography 
  • Magnetic Resonance Imaging 
  • Cone Beam Computerized Tomography 
  • Micro Computerized Tomography
  • 3D Laser Scanning
  • Stereophotogrammetry 
  • 3D Facial Morphometry 
  • Tuned Aperture Computed Tomography 

A 3D image is an object that gives the impression of being deeper than it is. When two or more photographs taken at different distances and angles are combined; a computer can construct a 3D image using the principles of stereoscopic vision. In radiography, a representation of an object is reconstructed from multiple 2D image views by employing complex mathematical rules and calculations.

3D imaging often employs two slightly separated lenses on a still or motion camera to capture an object’s three-dimensionality in a shot. The procedure simulates how human eyes perceive stereoscopic depth. The image is split into two halves and presented to the viewer’s eyes and brain separately, giving the impression of depth.

Use of 3D Imagery in Orthodontics

It wasn’t until the development of 3D imaging systems that structures could be analyzed in their true, anatomical 3D. You can see every detail of the craniofacial region, from the hard to the soft tissues. Since most of these systems are entirely non-invasive, the repeated use of images does not produce an ethical dilemma. You can also store 3D orthodontics images digitally, minimizing storage space. The evolution of software tools makes it possible to generate accurate and dependable 3D analysis.

Patients with malformations of their teeth and mouth can benefit significantly from 3D imaging technology. Orthodontists can use these 3D images to help patients correct misaligned teeth, adjust their bite, and fix jaw irregularities. 

Benefits of Three-Dimensional Orthodontic Imaging

Orthodontists can gain new insights and better care for their patients thanks to 3D imaging technology. Incorporating 3D imaging into the patient care process allows orthodontists to develop plans more quickly and precisely. Among the many advantages of 3D imaging are the following:

3D Imaging Gives Details

Without complete information, orthodontists would have to speculate about the nature of underlying tissues and root structures before coming up with a treatment plan. Structures below the gums, like roots and bones, can be visualized in 3D, shedding light on the impact of these elements on growth and development. The field of orthodontic can now generate more precise interactive treatment plans after visualizing facial structure extensively.

3D Imaging Monitors Growth and Development

By visualizing a patient’s anatomy in 3D, orthodontists can more accurately predict and monitor their patients’ growth and development.

3D Imaging Offers Quality Images

3D images give more precise information than previous 2D scans, allowing orthodontists to better tailor your treatment to your individual needs. The scan can be taken quickly and doesn’t hurt. 3D technology’s capacity to simultaneously take an image of bone and soft tissue is a huge benefit. The examination also does not expose the patient to any residual radiation.

3D imaging is revolutionizing orthodontics. It is beneficial not only to patients but also orthodontists. 3D images give these doctors very precise details aiding their understanding of certain problems. As a result, it helps doctors to make an accurate diagnosis and create an individualized treatment plan.
