Telerentgenogram: what is it, its functions and types

Telerentgenogram( TGG) is an additional method of research used in orthodontic practice to determine the size and features of the location of the jaws relative to each other and to the facial skeleton. This is a complete panoramic snapshot of the entire skull,

which is made in two projections: straight and lateral. Radiographic X-ray machine is used for research.

Telerentgenogram: what is it, its functions and types

Telerentgenogram allows you to clearly identify the type of bite.

TGG allows you to clearly identify the type of bite and the presence of any pathologies of the maxillo-facial skeleton. The research that should be done before the onset of treatment will help to detect anomalies of jaw growth, as well as to determine the wrong position of the teeth on the jaws.

For such a picture, one can thoroughly study the features of the structure of the entire facial skeleton and the dynamics of its gradual growth. All changes that occur in the structures of the maxillo-facial skeleton during jaw growth and permanent orthodontic treatment will be reflected on the telerentgenogram.

Worth to know! It is this method of research will be one of the most informative to compile a detailed plan for the treatment of orthodontic patients.


Telerentogram has several basic functions:

  • skull shooting in direct projection;
  • shooting of the paranasal sinuses;
  • head image in side projection;
  • wrist swipe.

Special orthodontic images are used in orthodontics, which are necessary for the correct preparation of a plan for the treatment of orthodontic patients.
Important! With such a shot, you can determine the exact location of the teeth on the jaws and assess the condition of the joints at the start of treatment.

Shots of the sinuses are needed during implantation. Such a picture helps to determine the location of the perineal sinuses, the condition of their mucous membranes. Gives the implant to understand whether it is possible to conduct treatment without prior surgical intervention.

Major types of

There are 3 main types of telerentgenography:

  • Axial telerentgenography of the head. This species is used only in conjunction with the direct and lateral TRG for a better study of the structure and form of the head in three mutually perpendicular planes.
  • Direct telerentgenography of the head. Most often used in orthopedic practice. With this snapshot you can determine the size of the skull in the vertical and transverse directions. Direct TGG is also used to study the asymmetry of a person, which appeared due to displacement of the mandible in one direction or was due to the presence of the congenital cleft of the maxillofacial region.
  • Side telerentgenography of the head. This method of investigation is most often used by orthodontists when drawing up a treatment plan. At the same time, in the pictures you can see the anomalies present in relation to the growth of the jaw and inappropriate bite. The image in the lateral projection is necessary for studying the structure of the skull in the vertical and sagittal direction. This kind of radiography is necessary as an additional research method for patients who are expected to have a bracelet system.
  • Telerentgenogram: what is it, its functions and types

    The side telerentgenogram is used when preparing a treatment plan.

    The lateral telerentgenogram allows you to study the following parameters:

    • defining relationships and distances between individual points on the skull;
    • defines the proportionality of the size of individual sections of the skull to the bones of the facial skeleton;
    • measures all required jaw angles that are used to construct an orthodontic treatment plan for a patient.

    Such a study may help to determine the bite pathology of a child before forming a permanent bite and take all necessary preventive measures. Telerentgenogram - the most accurate and informative method of X-ray treatment, which is widely used in dental practice.
