概括
扭矩显著影响组织级植入物中聚乙基 (PEEK) 扫描体的精度,最佳结果在10Ncm或以下. 骨水平的缩植入物显示出最小的差异,尽管发生了一些 mesial 倾斜.
科学领域:
- 牙科植入物学 牙科植入物学
- 生物材料科学是生物材料的科学.
- 牙修复 牙修复 牙修复 牙修复 牙修复
背景情况:
- 准确的数字印记对于牙科植入物修复至关重要.
- 聚乙基 (PEEK) 扫描体具有潜在的优势,但其精度需要评估.
- 了解扭矩对扫描体精度的影响对于可靠的数字工作流程至关重要.
研究的目的:
- 为了评估PEEK扫描体在骨水平逐渐缩小 (BLT) 和组织水平 (TL) 植入物上的水平和垂直差异.
- 为了研究不同扭矩水平 (5,10,15Ncm) 对扫描体精度的影响.
- 为了比较BLT和TL植入体系统之间的PEEK扫描体的性能.
主要方法:
- 78个PEEK扫描身体被放置在BLT和TL植入物上.
- 小组受到5,10和15Ncm扭矩的影响.
- 扫描电子显微镜 (SEM) 用于分析扫描体长度和角度.
主要成果:
- TL植入物显示出显著的垂直差异和缩短的扫描体长度与更高的扭矩.
- 对于TL植入物,在一个角度观察到水平偏差,特别是在较低的扭矩时.
- BLT植入物没有显著的垂直或水平差异,除了10Ncm的 mesial倾斜.
结论:
- 组织层面的植入物显示出受扭矩影响的显著偏差,最佳精度在≤10Ncm.
- 无论是TL和BLT组都经历了一定程度的水平转移和倾斜.
- 扭矩控制对于保持PEEK扫描身体精度至关重要,特别是在组织级植入体系统中.

01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
