The purpose of the present study was to developed a new core built-up fiber post using zirconium-containing glass fiber, Na_2O-K_2O-Ca0-ZrO_2-SiO_2, which possess superior mechanical prosperity, chemical durability, and biocompatibility. E glass was used for reference.Two types of molding method, pull-up method and continues heating polymerization method, were used for fiber post preparation. Mechanical properties of fiber post using both glass fibers were almost identical regardless molding methods.However, after hot water storage and thermocycling test (aged test), mechanical properties of the fiber post prepared with continues heating polymerization method were better than that with pull-up method.The mechanical properties of the fiber post using zirconium-containing glass fiber showed superior mechanical properties compared to that of dentin even after the aged test.

本研究以含锆玻璃纤维na22o - k22o - ca0 - zro_2 - sio_2为原料，开发了一种具有优异力学性能、化学耐久性和生物相容性的新型核心复合纤维桩。以E玻璃为参照。采用拉拔法和连续加热聚合法两种成型方法制备纤维后置。无论采用何种成型方法，两种玻璃纤维制成的纤维桩的力学性能几乎相同。然而，经过热水储存和热循环试验（老化试验），连续加热聚合法制备的纤维桩的力学性能优于拉拔法。含锆玻璃纤维纤维桩的力学性能即使经过老化试验，仍表现出优于牙本质的力学性能。
