磁力正牙的组织学研究

The Histological Study of Magneto-Orthodontics in Monkey

用稀土永磁材料钕铁硼对12只猴进行了磁力正牙实验,对受磁力作用后2,3,4和8周的猴牙周组织作了光学显微镜检查。结果表明:磁力作用后,猴牙周组织发生了理想的改建,且有速度快、损伤小、血液循环丰富的特点。

Magneto-orthodontic experiment with rare earth magnets Nd_2Fe_(14),B on twelve mon-keys were made.After 2,3,4 and 8 weeks,the periodontium of monkeys activated by ma-gnetic force were carefully examined under microscope.The result showed that the perio-dontium had taken on an ideal remodeling after the action of magnetic force.Fast speed,less periodontal lesion and abundant circulation were its character.
