Teleroentgenogram (TRG) is an X-ray examination necessary for orthdontological therapy planning. TRG image is made by means of long-distance radiography thus producing not distorted object (skull) due to parallel direction of X-rays due to the increased distance between the object and the X-ray tube head.
Types of TRG Images
There are frontal and lateral projection teleroentgenograms:
- TRG in direct projection enables dentition diagnostics in transversal direction. It makes it possible to assess the symmetricity of structures of the right and left halves of face and scull.
- TRG in lateral projection in sagittal direction make it possible to assess jaws location in the space and teeth displacement in anterior-posterior dimension.
Teleroentgenogram makes it possible to obtain an image corresponding to the size and shape of scull.
What kind of Teleroentgenogram Does Orthodontologist Need
For an orthodontologist TRG image in lateral projection is compulsory for diagnostics and treatment planning. For this purpose the image must be interpreted and calculated by means of application of the bone points and on the soft tissues lines are made between them, forming angles; after that mathematic calculations are made. It allows the orthodontologist to make a correct diagnosis and determine conditions for orthodontological treatment: type of growth, tooth joint plane (occlusion plane), teeth inclination and optimal location and spatial position of the lower jaw towards the upper one.
In the aesthetic dentistry clinic PRIZMA in Kiev the calculation is made by means of the program DOLPHIN. After teleroentgenogram interpretation an orthodontologist understands if orthodontology treatment is enough in this case or otognatic therapy is necessary (in case that the determined pathology is of skeleton nature abd not of teeth and alveolar one). TRG image and its results are stored in the DOLPHIN database and can be printed out for the patient when necessary.
