概括
异种移植最好在孔保存期间在冠状层面保存口腔壁,与自体移植和全体移植不同. 然而,所有骨移植材料在更深的区域显示了类似的结果,总体上发生了显著的再吸收.
科学领域:
- 牙科植入物学 牙科植入物学
- 在口腔外科手术.
- 生物材料科学 生物材料科学
背景情况:
- 在牙科植入物学中,孔的保存至关重要,以防止牙拔除后膜脊的再吸收.
- 保持口腔壁的完整性对于植入物稳定性和美观性至关重要.
- 有限的比较数据存在于不同的骨移植材料如何影响口腔壁的保存.
研究的目的:
- 为了比较自体移植,异体移植和异体移植对口腔壁尺寸在插座保存期间的影响.
- 通过使用先进的成像和分析技术,评估不同骨移植材料在保护口腔壁厚度方面的有效性.
主要方法:
- 对23名接受插座保护的患者进行了回顾性比较队列研究.
- 将它们分为三组:自移植,全移植和异种移植.
- 使用3D Slicer®对形束计算断层扫描 (CBCT) 扫描 (手术前T0和手术后6个月T1) 的分析,用于叠加和测量三级 (L2,L4,L6) 的口腔壁厚度.
- 使用Kruskal-Wallis和Wilcoxon签名等级测试进行统计分析.
主要成果:
- 与自体移植和异体移植 (P=0.02,P=0.04) 相比,异体移植在冠状层 (L2) 显著更好地保留了口腔壁厚度.
- 在更深层次 (L4,L6) 发现口腔壁保存没有显著差异.
- 在所有组中,口腔壁尺寸从T0到T1在所有水平 (P < 0.001) 显著下降,在总体再吸收率上没有统计学上显著的差异.
结论:
- 异位移植显示出优越的冠状口腔壁保存,使它们在孔保存中有利于美学结果.
- 所有移植材料在更深的区域都表现出类似的效果,尽管进行了移植,但仍发生了显著的再吸收.
- 需要进一步研究更大的样本大小和更长的随访,以优化长期植入成功的临床方案.

Pilot and Numeric Relaying
487
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Support Reactions in Three Dimensions
1.6K
Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system from translating and rotating, ensuring the design can withstand external forces and perform its intended function efficiently and safely. Some of the supports providing support reactions in three dimensions are discussed below:
Ball and Socket Joint is one of the supports allowing free rotation about any axis. This freedom of rotation is...

Relative Velocity in One Dimension
10.1K
The understanding of the concept of reference frames is essential to discuss relative motion in one or more dimensions. When we say that an object has a certain velocity, we must state the velocity with respect to a given reference frame. In most examples, this reference frame has been Earth. For instance, if a statement reads that a person is sitting in a train moving at 10 m/s east, then it implies that the person on the train is moving relative to the surface of Earth at this velocity,...

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Relative Velocity in Two Dimensions
9.1K
Relative velocity is the velocity of an object as observed from a particular reference frame, or the velocity of one reference frame with respect to another reference frame. The concept of relative velocity can be used to describe motion in two dimensions. Consider a particle P and two reference frames S and S′. The position of the origin of S′ as measured in S is , the position of P as measured in S′ is , and the position of P as measured in S is , which can be evaluated by utilizing...
