| Research Abstract |
The objective of this study was to make measurement of traction force and to investigate change of the force during the maxillary distraction osteogenesis. Micro tension gauge was able to be customized and minimized to 23 mm. Tension of traction wires was measured in 8 cleft lip/palate patients treated by using rigid external distraction system. The force increased with daily activation (p<0.01) ; the force showed positive correlation with the amount of activation (p<0.01). Moreover, the maximum total force of the both sides measured through activation period within all 8 cases was 54N. On the other hand, a case in which the lower distraction efficiency was observed demonstrated the higher tension/activation ratio.
