To establish the diagnosis and treatment plan for skeletal Class ¥± malocclusion, patient¡¯s skeletal morphology, prognosis as well as the treatment effect is one of the important factor to consider.
Therefore, the present study classified analyzed the difference between initial(T1) and after use of activator(T2), and after finish of direct multi-bonding system treatment(T3) for Class ¥± malocclusion during growth period according to the treatment result(effective body length) and morphology of vertical skeletal type.
The experimental group was classified into two groups(1 group, 2 group) according to the effective body length change between before and after use of activator, showed good treatment effect of activator for patient with small mandible and large differential between maxilla and mandible, and short anterior facial height. And the difference between 1 and 2 group in the experimental group before treatment(T1) disappeared in the finished treatment (T3). But in contrast, the initial difference of T1 stage between a and b group in the control group did not disappear in the finished treatment (T3). In short, experimental group¡¯s treatment effect was much better than contrast group and the treatment effect was maintained and got stable results at comparison experimental group with contrast group.
Through this study, we can find activator¡¯s treatment effect and stable retention of that in growing Class ¥± malocclusion patients. By estimate of activator treatment effect through these results, we can establish the correct diagnosis and treatment plan for adolescent Class ¥± malocclusion estimate of activator treatment effect and lead the ideal facial growth pattern.
