Abstract
Posted teeth were evaluated to determine the reinforcement capabilities of various post lengths. The results suggest that as internal tooth structure is removed from the tooth the tooth becomes weaker, that teeth with posts do show more reinforcement than nonposted teeth with the same manipulation characteristics, and that some load transfer appears to exist with cemented posts.
摘要
对桩核牙进行评估，以确定不同桩长度的增强能力。结果表明，随着牙体内部结构从牙齿中被去除，牙齿会变得更脆弱；具有桩核的牙齿在相同操作特征下确实比没有桩核的牙齿表现出更强的增强效果；并且对于粘结桩核，似乎存在一些载荷传递。
