| Research Abstract |
Treatment of the distraction osteogenesis on the upper jaw is the most effective treatment to improve occlusion and esthetics of the patients with cleft lip and palate. However, it is extremely difficult to move maxillary bone to the desireable position by using two screws equipped with the column fixed on the head.
The purpose of this study was to develop the monitoring system for the treatment of distraction osteogenesis on the maxillary bone. We became able to measure the traction power loaded on the maxillary bone in real time by using microminiature tension sensor. Also, we became able to observe the movement of the maxillary bone in real time by using ultrasonic imaging apparatus. Furthermore, the quantitative evaluation of the chewing function was developed using chewing gum including spherical resin particle.
A monitoring system for the treatment of distraction osteogenesis on the upper jaw was composed by putting together of these technique, and the utility of this monitoring system was confirmed.
