摘要
将离体上前牙进行根管治疗后分为4组,使用玻璃纤维桩修复后测试抗折裂强度。结果显示:牙本质肩领为2 mm组抗折裂强度较高。
The extracted human maxillary central incisors were endodontically treated and restored with glass-fiber post.Then they were randomly divided into four groups and tested.Results showed that groups with ferrule more than 2 mm had higher fracture resistence than others.
