Abstract:
Objective To understand the effects of Erigeron Breviscapus(EB) on suture osteogenesis during maxillary protraction in animal models.Methods The experiment was carried in 16 pubertal rabbits using self-made distraction devices during maxillary protraction,through which a forward elastic force(about 350 g) was exerted.During maxillary protraction,the experimental group underwent Erigeron Breviscapus,injected about(0.4mL) at either side of premaxilla-maxillary suture every day,and the control group were injected physiological saline.Undecalcified tissue slices labeled by serial tetracycline fluorochrome for 28 days were prepared for examination of the newly formed bone by computer image analysis.The results were compared between the two groups.Results The quantity of newly formed bone was significantly different between the two groups.The experimental group showed more newly formed bones than the control group.Conclusion EB can promote suture osteogenesis during maxillary protraction in the model.
