Abstract
There is lack of data for the amount of vertical bone in the midpalatal region for miniscrew implantation. The purpose of this study was to measure the structure of the midpalatal suture area using CT image and V-works 4.0 program (Cybermed Inc, Seoul, Korea). CT images of 14 male and 14 female adults were reconstructed. In detail, it was 1) to measure the length of maxilla on the midsagittal plane 2) to measure vertical bone height in the midpalatal area 3) to establish the zone of safety for miniscrew implantation. The following results were obtained, The mean length of ANS-PNS was 51.08 mm in males and 47.34 mm in females. There was a statistically significant difference between males and females (p < 0.05). The vertical bone height of the midpalatal suture area was above 6mm except for 15 mm posterior from the central point of ANS-PNS in males. The zone of safety was located 19.43 mm posterior from the ANS in males while it was 17.62 mm in females along the palatal plane. These results support that the safety zone of the midpalatal area is suitable for screw implantation. Midpalatal miniscrew implantation is a powerful tool in modern orthodontics. Through many applications, it can expand the modern orthodontic field.
