采用金属桩核和纤维桩树脂核修复残根残冠已很普遍,但由于金属桩核的颜色问题和纤维桩的抗折性差,其应用受到限制。氧化锆桩核具有较高弹性模量,在应力状态下形变较小,利于应力在桩和牙根之间传递,较纤维桩少发生桩折断且不影响全瓷冠修复的美学效果和MRI等影像学结果等特性,使其在临床上受到重视。本文对一体化氧化锆桩核的特性、应用范围、加工制作要求和临床粘接应用作一概述。
The use of metal post and fiber post resin core to repair residual root residual crown has been very common, but due to the color of metal post core and fiber post bending resistance, its application is limited. Zirconia post core with high elastic modulus, less deformation in the stress state, which is conducive to the stress transfer between the pile and the root, compared with the pile less pile fracture and does not affect the aesthetic effect of all-ceramic restoration and MRI images Learning results and other characteristics, make it clinically valued. This paper summarizes the characteristics, application range, processing and manufacturing requirements of the integrated zirconia post core and clinical adhesive application.
