The purpose of this study was to evaluate the soft tissue changes following FR-¥²
therapy. The sample consisted of 18 males and 15 females. The mean age of
pretreatment was 9.0 years in males and 8.3 years in females, and the mean treatment
time was 10.8 twos. in males and 12.2 mas. in females.
In this study the index method was adopted to exclude the effect of growth during
FR-¥² therapy.
The obtained results were as follows ;
1. In the linear measurement of male, Apex nasalis, Superior labial sulcus, Labrale
superior, Subspinale, and Incision superior moved forward significantly in both actual
and index value, Incision inferior, Supramentale, and Pogonion moved backward
significantly in both actual and index value, and Labrale inferior, Inferior labial sulcus,
and soft-tissue Pogonion moved backward significantly in index value.
2. In the linear measurement of female, Apex nasalis, Superior labial sulcus, Incision
superior moved forward significantly in both actual and index values, Labrale superior,
Subspinale in only actual value, and Incision inferior in both value, Labrale inferior,
Inferior labial sulcus in only index value moved backward significantly.
3. In the measurement of sort tissue thickness, Superior labial sulcus and Labrale
inferior of male increased in both actual and index value.
4. In the angular measurement, upper incisor angle of both sexes increased
significantly, facial convexity angle of both sexes decreased significantly, and upper lip
angle of male increased significantly.
5. In the measurement of differences between hard and soft tissue changes, there
were significant differences in between Subspinale : Superior labial sulcus, Incision
superior : Labrale superior, Incision inferior : Labrale inferior of male and Subspinale :
Superior labial sulcus of female in both actual and index value, and Incision superior :
Labrale superior of female in only index value. There was significant difference between
upper incisor angle change and upper lip angle change.
