There is are d for more accurate prediction in surgical orthodontic treatment. Video
imaging is an important technology in planning orthognathic surgery and educating
Patients about the esthetic results after treatment. Preoperative and postoperative lateral
cephalogram of 30 patients who had one piece Le Fort I osteotomy advancement and
mandibular set back by bilateral intraoral vertical ramal osteotomy with or without
genioplasty were used in this study. The computer generated soft tissue line drawing
prediction were compared with the actual postoperative cephalograms.
The results are as follows.
1. 14 variables showed Statistically significant differences from 24 variables between
computer predicted profile and post operative profile
2. Most of the differences were found in the maxilla-related soft tissue landmarks.
3. The predicted results were more accurate in the groups who had small amount of
mandibular set back.
4. The predicted results were more accurate in the groups who had no genioplasty.
Most of these differences were within 2mm ranges. Therefore profile change prediction
by video imaging could be considered clinically acceptable.
