-Abstract-
The treatment plan for orthognathic surgery must be based on accurate predictions,
and this can be produced the most esthetic results.
Treatment of prognathic mandible in adult is usually orthognathic surgery using
mandible set back, but mandible with retruded chin point os needed additional chin
augmentation. In this case, the directions between mandible and chin point are different
therefore, the prediction of soft tissue reactions must be modified.
In this study, we materialize the patients who was taken orthognathic surgery due to
prognathic mandible, 11each(Group A) was taken only Bilateral Sagittal Sprit Ramus
Osteotomy (BSSRO), 9each(Group B) was taken additional advancement genioplasty. The
lateral cephalometric radiography taken 8 months later after orthognathic surgery by this
patients were used.
The results of this study were as follows
1. The profile of lips was favorable after surgery due to upper lip to E-line became
prominent and lower lip to E-line was retruded.
2. In both group, upper lip moved posteriorly and national angle was increased.
3. The ratio of the soft tissue profile change in POGs point to skeletal B point
movement was 84% in group A and 66% in group B, and there was statistical
significance between group A and group B.
4. Vertical movement of hard tissue points is decreased in group A.
