In this research, the pubertal five-week-old SD rats were chose as experimental object to establish the animal model for simulating maxillary protraction, on which was imposed the orthopedic force of 85g with utilizing the self-devised maxillary protraction appliance. Located lateral X-ray cephalograms were taken to measure and analyze the changes of maxillary development after exerting the orthopedic force for 4 weeks. The technique of immunohistochemistry was used to investigate theexpression of TGF-, in frontomaxillary sutures and palatomaxillary sutures with identical force performing for different extent of time. The average hue was selected as indicator, which was measured by the means of the analysis system of pathological color images. The measuring data were analyzed by the one-way ANOVA in software SPSS 11.0 version.
