概括

聚乙基 (PEEK) 作为植入物保留假肢的基底结构具有前途. 表面处理,如研磨和等离子蚀刻增强粘合,而激光和涂层显示效果较差.

科学领域:

生物材料科学生物材料科学
聚合物科学聚合物科学
牙修复牙修复牙修复牙修复牙修复

背景情况:

烯酸树脂和之间的粘合问题在牙修术中很常见.
像聚乙 (PEEK) 这样的高性能聚合物为植入物和假肢基结构提供了潜在的解决方案.

研究的目的:

评估各种表面处理对PEEK与面弹性体的结合强度的影响.
确定PEEK作为植入体支的假肢的替代基结构材料的适用性.

主要方法:

从PEEK和聚甲基甲酸 (PMMA) 制造了48个标本,PMMA作为阳性对照.
对PEEK进行了五种表面处理:控制,涂,等离子蚀刻,研磨和纳米秒光纤激光.
通过SEM评估表面地形,并在涂上白金原料后,使用白金类型的弹性体测试皮层结合强度.

主要成果:

对照PEEK表现出最高的结合强度. 对照PEEK,研磨和等离子蚀刻组之间没有发现显著差异.
激光治疗组表现出最低的结合强度,在统计学上与涂层没有什么不同.

Carbon Skeletons

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side chains...
