Abstract
The purpose of this study was to find the characteristics of lateral cephalogram of skeletal class III malocclusion patients to whom orthognathic surgery was essential.
For this study 37 patients with skeletal class III and going to treat or be treated orthognathic surgery(age 7 - 17) were selected to experimental group and 56 people with normal occlusion ( age 8 - 13) were selected to normal group and the two groups were evaluated and statistically analyzed and the results were as follows
1. In comparison of experimental group and normal group in prepubertal group, there were significant differences in ANS-Ul/Me-Li, Mx. Length/Mn.Length, S-N/Go-Me, Wits, ANB, SN-Pog, IMPA, Facial Convexity, APDI (P<0.05)
2. In comparison of experimental group and normal group in pubertal group, there were significant differences in ANS-Ul/Me-LI, S-GoN-Me, Mx.LengtWMn.Length, S-N/Go-Me, Wits, Saddle Angle, SNB, ANB, SN-Pog, R MA, Interincisal Angle, Facial Convexity, APDI (P<0.05)
3. Among items showing characteristics of skeletal class M malocclusion, there were no significant differences between
prepubertal group and pubertal group in other items except Mx. LengtblMn. Length, APDI {P4. The significant correlationship was the highest between Saddle Angle and SNB, SN-Pog and SNB, ANB and Facial
Convexity in experimental group
