概括
对于使用圆束计算机断层扫描 (CBCT) 进行精确的下测量,将闭合平面平行于地平线的方向是优越的. 这种头部方向提供了比使用下平面更精确的线性骨高度和宽度评估.
科学领域:
- 牙科 牙科是指牙科的专业.
- 放射学 放射学是一门学科.
- 人体解剖学 解剖学 解剖学
背景情况:
- 圆束计算机断层扫描 (CBCT) 对于评估骨尺寸至关重要.
- 准确的下骨线性测量对于诊断和治疗计划至关重要.
- 头部方向对CBCT测量的影响需要澄清.
研究的目的:
- 为了比较 mandibular 线性测量的准确性,使用 CBCT 中的 occlusal 平面与 mandibular 平面定向.
- 为了确定最佳的头部方向,以可靠的CBCT为基础的下骨评估.
主要方法:
- 使用CBCT扫描了五个干燥的人类下.
- 大的高度和宽度在特定位置测量 (切口,狗,前,).
- 测量时,闭合平面和下平面与地平线平行,并与口径测量进行了比较.
主要成果:
- 与封闭平面对齐的测量通常更接近标准值.
- 在平面和口径测量之间,在狗和前部位的骨高度中发现了显著的差异.
- 在部部位的测量结果中没有发现显著差异.
结论:
- 将闭合平面与地平线对齐可以获得更准确的CBCT线性测量下高度和宽度.
- 建议以闭塞平面定向作为基于CBCT的下骨测量的首选参考.

01:10Computed Tomography
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...
