Abstract
Aim of the study was to study lateral TRG in 43 patients with grade III vertical disocclusion of the dentition at the age of 7 to 18 years.
Material and methods. Lateral telerentgenogram were used to study the angle indices SN-NL, SN-ML, NL-ML, showing the ratio of the upper and lower jaw relative to the base of the skull and relative to each other.
The highest values of the SN-NL angle were observed in children of 1 group at the age of 18 years — 9.0°, in 2 group at the age of 18 years — 9.3°, in 3 group at the age of 17 years — 8.9°. The lowest values of the SN-NL angle were observed in children of group 1 at the age of 7, 8, 10 years — 7.5°, in group 2 at the age of 7 years — 8.5°, in group 3 at the age of 7 years — 8.4°.
The highest values of the SN-ML angle were observed in children of group 1 at the age of 15, 16, 17, 18 years — 33°, in group 2 at the age of 18 years — 37°, in group 3 at the age of 17, 18 years — 36°. The lowest indices of the angle SN-ML was the children 1 age group 12 years — 31° in group 2 at the age of 11 — 33°, group 3, ages 11, 12, and 13 — 34°. The highest values of NL-ML — 34° angle were observed in children aged 17 years from group 1, in group 2 at age 17, 18 years — 33°, in group 3 at age 13, 14 and 18 years — 30°. In children of group 1 aged 7, 8, 11, 2 groups at the age of 9, 10 and 3 groups at the age of 8 years identified the least parameters of an angle NL-ML — 28°, 28°, 27°, respectively.
Results. As a result of the study, it was noted that in children with vertical dysocclusion of the dentition of the third degree, the angles SN-NL, SN-ML, NL-ML have high indicators, which characterizes the vertical type of skull growth.
