(1)The fracture strength of structurally compromised tooth with flared root canal was high value when the cast metal post and core was cemented after the reinforcement of the tooth structure used resin composite together with the clear acrylic post.(2)Composite resin cores with the experimental posts without glass fiber have similar fracture strength to that with prefabricated glass fiber posts and the fracture strength of endodontically treated teeth restored with composite resin cores is not influenced by the flexural modulus of these posts.

（1）对于结构受损的扩口根管牙，采用树脂复合材料结合透明丙烯酸树脂桩加固牙体结构后，再进行铸造金属桩核粘接，其抗折强度较高。（2）不含玻璃纤维桩的复合树脂核与预制玻璃纤维桩的断裂强度相近，复合树脂核修复的根管治疗牙的断裂强度不受桩的弯曲模量的影响。
