牙根埋藏是防止牙槽嵴吸收,有利于义齿修复的一种方法。是在牙槽嵴以下1～2毫米切断牙根,用龈瓣将断面完全复盖,促进断根端骨的形成。文献曾报告三种保留牙根的方法:①保存牙根的牙髓活力。②经根管治疗的牙根。③将牙根拔除,经根管治疗后切断牙根,再重新植入。赞同第一种方法者指出,健康牙髓组织与其上的结缔组织融合,继之根管逐渐为骨牙本质所闭合。有些病例报告在埋藏牙根上方最终有骨形成。赞同第二种方法者也报告了在一些病例有骨形成。这表明牙髓组织对此法的成败无关。第三种方法的理论基础是导致牙根与骨粘连,
Buried root is to prevent alveolar ridge absorption, is conducive to the denture repair method. In the alveolar crest 1 to 2 mm cut off the root, the gill flap to completely cover the cross section, to promote the formation of end roots. The literature has reported three ways to retain the root: ① preservation of dental pulp vitality. Root canal treatment of root. ③ remove the root, root canal treatment after cutting the root, and then re-implanted. In favor of the first approach, it is pointed out that healthy pulp tissue is fused with the connective tissue thereon, followed by gradual root canal closure of the dentin. Some cases report the formation of bone at the root of the underlying burial tooth. Those who agree with the second method also report bone formation in some cases. This shows that pulp tissue has nothing to do with the success of this method. The third method is based on the theory that causes root and bone adhesion,
