Abstract

This study investigated the mechanical properties and single crown accuracy of the tailor-made Fourth University Stomatology investment (FUS-invest) for casting titanium. . Current investment for casting titanium is not optimal for obtaining high-quality castings, and the commercially available titanium investment is costly. . Titanium specimens were cast using the tailor-made FUS-invest. The mechanical properties were tested using a universal testing machine. Fractured castings were characterized by energy-dispersive spectroscopy. 19 titanium crowns were produced using FUS-invest and another 19 by Symbion. The accuracy of crowns was evaluated. . The mechanical properties of the titanium cast by FUS-invest were elastic modulus 125.6 ± 8.8 GPa, yield strength 567.5 ± 11.1 MPa, tensile strength 671.2 ± 15.6 MPa, and elongation 4.6 ± 0.2%. For marginal fit, no significant difference ( > 0.05) was found at four marker points of each group. For internal fit, no significant difference ( > 0.05) was found between two groups, whereas significant difference ( < 0.01) was found at different mark point of each group. . The mechanical properties of titanium casted using FUS-invest fulfilled the ISO 9693 criteria. The marginal and internal fit of the titanium crowns using either the FUS-invest or Symbion were similar.

摘要

本研究探讨了定制第四大学口腔投资（FUS-invest）用于铸造钛的机械性能和单冠精度。 目前用于铸造钛的投资并不是获得高质量铸件的最佳选择，而市售的钛投资成本高昂。 使用定制的 FUS-invest 铸造钛样本。 使用万能试验机测试机械性能。 通过能量色散光谱法对断裂铸件进行了表征。 使用 FUS-invest 生产了 19 个钛冠，使用 Symbion 生产了另外 19 个。评估了冠的精度。 FUS-invest 铸造的钛的机械性能为弹性模量 125.6 ± 8.8 GPa、屈服强度 567.5 ± 11.1 MPa、拉伸强度 671.2 ± 15.6 MPa 和伸长率 4.6 ± 0.2%。对于边缘拟合，在每组的四个标记点处未发现显著差异（>0.05）。对于内部拟合，两组之间未发现显著差异（>0.05），而在每组的不同标记点处发现了显著差异（<0.01）。 使用 FUS-invest 铸造的钛的机械性能符合 ISO 9693 标准。使用 FUS-invest 或 Symbion 的钛冠的边缘和内部拟合相似。
