영문 초록

The purpose of this study was to evaluate the parts of discrepancy on orthognathic surgical cases with skeletal Class Ⅲ malocclusion. For this study, Ricketts analysis that has suggested visual treatment objective, as named for growth predictable blue print, was used. The results of this study were as follows: 1. in the denture problem, mandibular incisor and molar was positioned more anteriorly in Class Ⅲ malocclusion. 2. The location of A point was characteristically posteriorly positioned in the Class Ⅲ group, and mandible plane angle was within normal range in the groups. 3. Position of upper and lower anterior teeth to A-Pogonion line was anteriorly positioned, and angulation of upper anterior tooth was lingually positioned in the Class Ⅲ group, but angulation of lower anterior tooth was not significant in the both groups. 4. Esthetic line of Ricketts analysis was not significant statistically. 5. Facial depth and axis was larger, but facial taper(facial plane ⊥ mandible plane) was smaller in the Class Ⅲ group. So, protruded and concave profile was seen in the Class Ⅲ group. 6. Cranial deflection was larger in the Class Ⅲ male group, ramus location was anteriorly positioned and mandibular length was enlarged in the male and female of Class Ⅲ group.
