钕铁硼磁铁是一种磁力较强的稀土磁铁,用于口腔修复医学效果良好。方法:1.按前牙、双尖牙、磨牙牙根的大小制成4min×3mm、3mm×3mm、3mm×2mm厚度为1.5mm不同磁铁植入牙根内。2.磁性义齿制作:磁性义齿是利用磁体两极相吸的原理而固定的义齿。牙根的制备及磁体置入:该义齿选用健康及利于植入磁体的牙根,根管治疗后,牙龈上留出2mm高度,其余牙冠全部磨掉,消除倒凹,磨钝周边,在牙冠上备出可放磁体的洞型,隔湿和吹干洞型将磁
NdFeB magnet is a strong magnetic rare earth magnet, used for oral repair of the medical effect is good. Method: 1. According to the size of the anterior teeth, bicuspid teeth, molar teeth made of 4min × 3mm, 3mm × 3mm, 3mm × 2mm thickness of 1.5mm different magnets were implanted in the root. 2 magnetic denture production: magnetic denture is the use of magnets bipolar principle of absorption and fixed denture. Preparation of the root and the magnet insertion: The denture is selected to be healthy and conducive to implantation of the root of the magnet. After root canal treatment, the gum is left with a height of 2 mm, and the rest of the crown is worn away to eliminate the undercut and blunt periphery. On the prepared magnet can be placed in the hole, separated from the dry and dry hole will be magnetic
