摘要
牙冠大面积缺损的修复方法首选桩核冠。目前,有关桩核的材料也从传统的钢性材料转变为生物性能更接近牙本质的材料,如纤维桩。考察纤维桩修复后远期疗效的指标是其整体抗折强度。本文拟对影响纤维桩修复后其整体抗折强度的因素作一综述。
Fiber post and resin core systems were applied in the restoration of residual roots.At present, the restorative materials are gradually transferred from traditional rigid materials to composite materials whose biomechanical properties are close to dentin, such as fiber post.To restore endodontically treated teeth with fiber posts and composite resin,long term effect index is fracture resistance.This paper is focused on the influencing factors of fracture resistance of fiber posts.
