概括

在透明的对齐器材料和附件之间存在微观的差距,影响治疗的有效性. 优化的附件和多层材料,如Zendura FLX,显示出更好的适应性,尽管不完全合适.

科学领域:

牙整形
生物材料科学
牙科材料

背景情况:

清晰对齐器治疗的有效性依赖于对齐器-附着接口的精确力传输.
调整器材料和附件设计之间的微观兼容性对于可预测的治疗结果至关重要.

研究的目的:

评估Duran+和Zendura FLX透明调整器材料和矩形与优化接设计之间的微观适应性.
通过扫描电子显微镜 (SEM) 识别影响对齐器与附件接口间隙形成的材料和设计因素.

主要方法:

采用Duran+/矩形,Zendura FLX/矩形,Duran+/优化和Zendura FLX/优化四个组编制了56个牛切口样本.
透明对齐器经过热成型,并通过SEM在250倍放大时进行横截面分析.
在每个附件类型的定义点系统地记录了间隙测量.

主要成果:

间隙大小差异很大,从14.75±1.41μm到91.07±3.11μm不等.
与具有矩形附件的Duran+相比,Zendura FLX表现出更好的适应性 (p < 0. 001).
优化附件的整体适应性比矩形设计更好,牙边界的间隙最大,口腔表面的间隙最小.

结论:

没有经过测试的材料-附着组合实现了完美的显微镜适应.
材料特性 (例如多层Zendura FLX) 和附件几何形状 (优化设计) 都对适应有很大影响.
这些发现为清晰对齐器治疗的临床局限性提供了机械洞察力,并指导了材料/设计选择.

Preparation of Samples for Electron Microscopy

Preparation of Samples for Electron Microscopy

To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...

Overview of Microscopy Techniques

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Overview of Electron Microscopy

The wavelengths of visible light ultimately limit the maximum theoretical resolution of images created by light microscopes. Most light microscopes can only magnify 1000X, and a few can magnify up to 1500X. Electrons, like electromagnetic radiation, can behave like waves, but with wavelengths of 0.005 nm, they produce significantly greater resolution up to 0.05 nm as compared to 500 nm for visible light. An electron microscope (EM) can create a sharp image that is magnified up to 2,000,000X.
