Abstract

Objectives: This study aimed to clarify the effect of metal elements in the coloring liquids used in the infiltration method on the physical properties of zirconia.

Methods: Two types of zirconia discs 5Y-PSZ (SHOFU Disc ZR Lucent FA, SHOFU, Kyoto, Japan) were used: with monolayer shades from W2 to W3 (Pearl White) and 5Y-PSZ with multilayer shades from A3 to A4 (L). Five kinds of coloring liquid were used to infiltrate into semi-sintered Pearl White (T-glass [CT], A4 [CA], White-Opaque [CW], Gingiva 1 [CG], and Blue X [CB]). In addition, uncolored Pearl White set to as the control (C). These specimens were analyzed using a three-point bending test (3PBT), and the fracture surface after the test was analyzed by scanning electron microscopy, elemental analysis, and crystal structure analysis. In addition, from the polished surface part of the after the 3PBT specimens, the elemental composition was analyzed using X-ray fluorescence spectroscopy (XRF).

Results: The flexural strength of CB and CG were lower than that of C (p < 0.05). XRF results showed that the Erbium (Er) content of CG was significantly greater than that of C (p < 0.05). CB exhibited a significantly higher Yttrium (Y) content compared with C (p < 0.05), and numerous pores were observed in the micrographs of the fracture surface of CG and CB.

Significance: In zirconia, where the content of Y and Er was significantly increased by infiltration with a coloring liquid, pores were observed between the zirconia crystals, and the mechanical strength decreased.

浸润法所用着色液中的金属元素对氧化锆物理性质的影响。

研究目的本研究旨在阐明浸润法所用着色液中的金属元素对氧化锆物理性质的影响：使用了两种类型的氧化锆盘 5Y-PSZ（SHOFU Disc ZR Lucent FA，SHOFU，日本京都）：单层色调从 W2 到 W3（珍珠白）和多层色调从 A3 到 A4（L）的 5Y-PSZ。在半烧结珍珠白中渗入了五种着色液（T-glass [CT]、A4 [CA]、White-Opaque [CW]、Gingiva 1 [CG] 和 Blue X [CB]）。此外，未着色的珍珠白设为对照组（C）。对这些试样进行了三点弯曲试验（3PBT）分析，并对试验后的断裂面进行了扫描电子显微镜分析、元素分析和晶体结构分析。此外，还利用 X 射线荧光光谱（XRF）分析了三点弯曲试验后试样表面抛光部分的元素组成：结果：CB 和 CG 的抗弯强度低于 C（p）：在用着色液浸润的氧化锆中，Y 和 Er 的含量显著增加，氧化锆晶体之间出现气孔，机械强度降低。
