This article focused on the influence of the zirconia thickness on the strength of the veneer porcelain, which was evaluated with a fracture toughness test according to JIS R 1607. The veneer porcelains for the zirconia all-ceramic crown were fired on two different thicknesses (0. 4 mm and 0. 8 mm)of zirconia frames (ZAC). As the controls, veneer porcelains fired on metal frames for porcelain fused to metal crown (PFM)were used. The fracture toughness value evaluated by measuring the extent of cracking associated with a Vickers indentation on the veneer porcelain part was significantly lager at the points of 1. 5 mm in 0. 4 mm thickness frame of ZAC samples compared with in the 0. 8 mm frame.

本文侧重于锆层厚度对贴面瓷器强度的影响，根据JIS R 1607的裂缝韧性测试，对氧化锌的瓷器进行了评估。氧化锆全陶罐的贴面瓷器在两个不同的厚度上发射了两个不同的厚度（0。4mm和0。4mm和0。8mm）。当对照组中，使用了与金属冠（PFM）的金属框架上发射的贴面瓷器。通过测量与饰面瓷器部分上与维克斯凹痕相关的裂纹程度评估的断裂韧性值在0。4mm厚的ZAC样品框架的1。5mm处显着落后，与0. 8 mm框架相比。
