| Research Abstract |
The objective of this study was to measure the traction force during distraction osteogenesis in patients showing lateral deviation of the maxilla using a RED system. For the study period, a micro tension gauge was customized and minimized to a length of 19 mm.
Tension of traction wires were measured in 6 cleft lip/palate patients treated using maxillary distraction osteogenesis. The mean distance of maxillary advancement was 8.6 mm, while the maximum traction force, which was calculated by averaging the tension of the right and left side, was found to be 18.5 N. A statistically significant positive correlation was observed between the amount of maxillary advancement and traction force.
In a patient with a cleft lip and palate showing lateral maxillary deviation, acceptable occlusion was obtained using the RED system with three traction wires. Application of differential forces was effective for correction of the anteroposterior as well as lateral displacement of the maxilla.
