概括

可压缩陶面板 (PCV) 与间接复合面板 (ICV) 和CAD/CAM陶面板相比,提供更好的边缘适应. 牙医在为最佳的临床结果选择 Veneer 材料时应考虑边缘适合.

科学领域:

牙科材料科学牙科材料科学
牙修复牙修复牙修复牙修复牙修复
生物材料工程生物材料工程

背景情况:

牙贴片的精确边缘适合对于长期的修复成功和预防次要牙至关重要.
通常使用的贴面材料包括间接复合材料,可压陶和CAD/CAM制造的陶.
制造技术和材料的变化可能会影响面板的边际适应.

研究的目的:

为了比较三种流行的牙贴片类型的边缘适合性:间接复合贴片 (ICV),可压缩陶贴片 (PCV) 和计算机辅助设计/计算机辅助制造 (CAD/CAM) 陶贴片.
量化每种 Veneer 类型的牙边缘特定位置的边际差异.
为了确定哪种 Veneer 材料表现出临床上最可接受的边缘适合.

主要方法:

在烯酸树脂中嵌入的部中央切口器的标准化制备.
制造30个面板,分为三个组:ICV,PCV (二酸盐) 和CAD/CAM陶 (二酸盐).
用立体显微镜在定义的唇部和部边缘点评估边际差异,然后进行统计分析 (ANOVA,Tukey测试).

主要成果:

可压缩陶面板 (PCV) 显示了最小的平均边际差异 (48.2微米宫, 40.58微米 palatal).
在CAD/CAM陶面板上显示了中等差异 (94.24微米宫,52.72微米口腔).
间接复合面板 (ICV) 显示出最大的边际差异 (189.24微米宫,79.01微米 palatal).

结论:

可压缩陶面板在测试材料中提供最好的边缘适合性,其次是CAD/CAM陶面板.
间接复合面板显示最差的边缘适合.
无论是PCV还是CAD/CAM陶面板,都在临床上可接受的范围内显示出边际差异,这突显了材料选择对于可预测的临床性能的重要性.

Veneer

Veneer

Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

Assessment of the Mouth

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
