把稀土永磁材料用于口腔正畸,国内外的研究均处于起步阶段。我们设计了用钕铁硼永磁体移动猴牙的实验,目的在于探讨该材料移动牙齿的可行性。 1 材料与方法 猴牙与人牙相似,且猴上颌侧切牙与尖牙之间有5～7mm的灵长间隙,便于作侧切牙远中移动,选年轻。恒牙列、身体健康的猕猴(购于四川)为实验对象,雌雄均有,共计12只。 The rare earth permanent magnet materials for orthodontic, domestic and foreign research are in its infancy. We designed an experiment to move monkey teeth with neodymium iron boron permanent magnets in order to investigate the feasibility of this material for moving teeth. 1 Materials and methods Monkey teeth and human teeth are similar, and the monkey maxillary lateral incisors and fangs 5 ​​~ 7mm between the primate gap, easy to move the lateral incisors, choose young. Permanent dentition, healthy macaques (purchased in Sichuan) as the experimental subjects, both male and female, a total of 12.
