概括
在II类骨患者中,大横向缺陷 (MTD) 与大骨厚度的改变有关. 一个更窄的部与增加的后面口腔厚度相关,影响垂直尺寸.
科学领域:
- 矯正牙醫和牙臉整形醫學
- 头骨和面部外科手术
- 放射学 (形束计算机断层扫描)
背景情况:
- 大横向缺陷 (MTD) 破坏了口腔神经系统的平衡和功能.
- 了解大骨尺寸对于用MTD治疗骨II类缺陷至关重要.
研究的目的:
- 在骨II类患者中,评估骨厚度在中侧 suture (MPS).
- 为了比较患有MTD的个体之间的骨厚度和正常的横向大宽度.
主要方法:
- 分析了来自骨II类患者 (≥18岁) 的111个CBCT扫描.
- 使用U-Penn方法将其分类为正常宽度 (n=46) 和MTD (n=65) 组.
- 测量前,中,后大骨厚度 (AMT,MMT,PMT) 和鼻腔通道厚度 (NCT).
主要成果:
- 在两组之间 (p<0.001) 观察到上腺缩指数 (5.82毫米) 的显著差异.
- 两组之间整体上厚度测量 (NCT,MMT,AMT,PMT) 没有显著差异 (p>0.05).
- 在MTD和NCT (R=0.202) 和PMT (R=0.205) 之间发现了较低但显著的相关性.
- 后大厚度 (PMT) 显著影响了MTD的发生;每毫米的PMT增加都会使缩指数增加0.78点 (p=0.005).
结论:
- 骨II类患者的横向大尺寸会影响垂直骨尺寸.
- 一个更窄的关节与更大的后面口腔厚度有关,无论最初的横向宽度如何.

Understanding beam deflection, particularly for indeterminate beams with overhanging segments and multiple concentrated loads, is crucial for ensuring structural integrity and functionality. The process begins with constructing an accurate free-body diagram, which helps identify the forces and moments acting on the beam. This diagram is vital for visualizing how bending moments vary along the beam's length, influencing its curvature.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Other adult family members and siblings play a crucial role in shaping children’s social and emotional development. While parents or primary caregivers are often the central figures in early attachment and socialization, other adults in a child’s life, such as grandparents, aunts, and uncles, can significantly influence developmental outcomes. These influences depend on each adult’s personality and may help compensate when a primary caregiver is emotionally distant or...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
