概括

随着时间的推移,3D打印牙科材料和CAD/CAM块的颜色变化增加,特别是当暴露在红酒中时. 在一周和一个月后,3D打印材料的变色明显比CAD/CAM块多.

科学领域:

牙科材料科学牙科材料科学
生物材料工程生物材料工程
在牙科领域的增材制造

背景情况:

数字牙科的进步引入了3D打印材料,作为传统CAD/CAM块的替代品.
评估这些新材料的长期稳定性和美学特性对于临床采用至关重要.

研究的目的:

为了比较3D打印牙树脂与含有陶的CAD/CAM块的色彩稳定性和半透明度.
在模拟的临床条件下评估这些材料的变色程度.

主要方法:

三个含有陶树脂的CAD/CAM块和一个3D打印树脂经过热循环处理.
在不同时间点在红葡萄酒中储存后,使用颜色差异测量 (∆E₀₀) 来评估变色.
使用重复测量ANOVA和Tukey的后期测试进行了统计分析.

主要成果:

所有测试材料的颜色变化 (∆E₀₀) 超过了在红酒中储存时临床上可接受的值.
与CAD/CAM块相比,3D打印材料在1周和1个月后显示出明显更大的变色.
随着时间的推移,3D打印树脂和CAD/CAM块的颜色变化增加了.

结论:

3D打印牙科材料和CAD/CAM块容易变色,特别是当暴露于红酒等染色剂时.
与评估的CAD/CAM块相比,3D打印的树脂显示颜色稳定性较差.
需要进行进一步的研究,以提高可3D打印牙科材料的耐性,以用于美学应用.

Brick Durability, Strength, and Appearance

Brick Durability, Strength, and Appearance

Brick durability, strength, and appearance are crucial factors in construction, influencing the choice of bricks for specific applications. The process of freeze-thaw, for instance, significantly affects brick durability. This phenomenon occurs when water absorbed by a brick expands as it freezes, potentially causing damage when it melts and refreezes. Bricks are graded for durability: SW-grade bricks are the most durable, offering high strength and low water absorption, followed by MW-grade...
