Diagnostics in orthodontics

Diagnosis is required before starting orthodontic treatment. Diagnosis may include various methods, on the basis of which the bite is examined, and the need for an additional research complex is identified.

Computed tomography in orthodontics is a good information method that helps to achieve certain progress in research and ensures high reliability of the results. When computed tomography is carried out layer-by-layer photographing of the desired areas.

Magnetic resonance imaging (MRI) – is part of a computer study of the diagnostic plan. MRI can be the only diagnostic method for some dental problems, as it clearly shows the depth of the pathology, its size and shape. If the doctor has an MRI result, additional diagnostic work is performed.

An orthopantomogram is a panoramic view of the jaws and teeth that allows you to get a visual picture of bone tissue. With a minimal radiological burden on the patient, an orthopantomogram will help to achieve high-quality images with a great overview. The pictures will show:

  • Major sinuses
  • Bone
  • Pathology that has visible boundaries
  • The root location

Different specialists try to apply the orthopantomogram: orthodontists, implantologists, therapists, orthopedists. For surgeons, sometimes these methods simply cannot be dispensed with.

X-ray in orthodontics (before installing braces) – X-ray examination, in which the image can be transferred to a film or computer (visiograph). A targeted x-ray helps capture the limited area that you need to study. Methods with less exposure can be given in the following order: orthopantomogram, computed tomography, magnetic resonance imaging, radiovisiography, TRG.

A teleradiogram (TRG) is a type of study in which the resulting image shows up to the smallest detail absolutely all the tissues of the area being taken. On the TWG, one can observe the relief, boundaries, and marginal sections. A teleradiograph is obtained in two projections: lateral or direct.

TWG helps:

  • Determine the level of passage of soft tissues of the oral cavity
  • Consider (in detail) bone tissue
  • Carry out an orthodontic analysis
  • Give an opinion on bone formations

You can use any of these methods after seeing a dentist who determines the method itself, its degree of significance and the need for this method before starting treatment. Orthodontic studies do not include all of the research methods listed above, but as a rule, two leading methods are used by orthodontists: an orthopantomogram and TRG .


After studying the provided images, the doctors prepare a treatment plan and draw up detailed calculations for the ongoing medical procedures. To carry out X-ray studies or to obtain a referral for studies, you need to contact a specialist who will appoint you an examination with the necessary pictures already included in his treatment plan.
