title: [THE RAPID TEST METHOD OF IDENTIFICATION OF THE TYPE OF GROWTH OF THE JAW BONE ON THE ORTHOPANTOMOGRAM].
abstract: The roentgenological methods of research take the lead in the diacrisis of dentofacial anomalies, they are of the utmost importance as for the identification of the jaws' growth character, so too for the generation of the treatment planning and of the expected response to the treatment. The type of the jaw growth is identified by the means of a basal angle on the teleroentgenography (TRG). The objective of the research was to develop a rapid test method of identification of the type of growth by means of a basal angle on the orthopantomogram (OPTG). The comparison of <B and of <G was conducted during the roentgenological research of 28 patients at the age from 13 to 29 years with the different forms of the dentofacial anomalies by means of the methods of dental x-rays, made through the use of TRG and OPTG. The dissimilarities are statistically insignificant (p>0,05) during the comparison of angles' indexes on the TRG and OPTG. The proposed rapid test method allows to identify the type of growth of the mandibular bones by the means of basal angle <B on the OPTG and to make allowance for the anatomic peculiarities of the structure of jaws on both sides in contradistinction from the TRG. The value <B is more than 25° on the OPTG - it denotes the retroinclination of the lower jaw bone and the vertical direction of growth, the index, which is lower than 15° bears record to the inclination of the lower jaw bone in an anteriad direction and in the horizontal direction of the growth.
