The goal of this work is to quantitatively examine the effect of adhesive resin cement on the probability of crack initiation from the internal surface of ceramic dental restorations. The possible crack bridging mechanism and residual stress effect of the resin cement on the ceramic surface are examined. Based on the fracture-mechanics-based failure probability model, we predict the failure probability of glass-ceramic disks bonded to simulated dentin subjected to indentation loads. The theoretical predictions match experimental data suggesting that both resin bridging and shrinkage plays an important role and need to be considered for accurate prognostics to occur.

胶粘剂树脂水门汀粘结牙科陶瓷的统计失效分析

这项工作的目的是定量检查粘性树脂水门汀对陶瓷牙修复体内表面裂纹萌生概率的影响。研究了树脂粘固剂对陶瓷表面可能的裂纹桥接机制和残余应力影响。基于基于断裂力学的失效概率模型，我们预测了结合到模拟牙本质上的微晶玻璃盘在承受压痕载荷时的失效概率。理论预测与实验数据相匹配，表明树脂桥接和收缩都起着重要作用，需要考虑到发生准确的预测。
