概括
使用口腔内扫描仪 (IOS) 的数字印记 (DIs) 与传统印记 (CI) 相比,对全弧牙部扫描的准确性较低. 然而,IOS在较短的跨度上是准确的,比如在5个单位范围内的固定假肢所需的.
科学领域:
- 牙科 牙科是指牙科的专业.
- 数字牙科数字牙科
- 牙科材料 牙科材料
背景情况:
- 内口扫描仪 (IOS) 越来越多地用于牙科治疗.
- IOS对于全弧印象的准确性仍然是争论的主题.
- 这项研究研究了使用IOS与传统方法的全弧扫描中的弧形变形.
研究的目的:
- 使用三台口内扫描仪,比较常规印记 (CI) 和数字印记 (DI) 之间的弧形变形.
- 为了评估六个不同的跨度的全弧和部分弧扫描的真实性.
- 确定当前IOS技术适用于不同临床应用的适用性.
主要方法:
- 标志性的标准化上下模型被用作参考.
- 使用材料和三个IOS (CS3600,Trios3,Trios5) 获得了15个常规印记 (CI) 和15个数字印记 (DI).
- 测量绝对线性偏差以评估距离和角度的真实性,并使用Kruskal-Wallis和ANOVA测试分析数据.
主要成果:
- 数字打印偏差随跨度长度增加,而传统打印偏差保持稳定.
- 在高达5个单位的跨度上,IOS显示出比CI更高的真实性 (P <0.05).
- 对于较长的跨度,CI显示的真实性明显优于评估的IOS (P<0.05).
结论:
- 当前口腔内扫描仪的准确性对于全弧牙科应用是不够的.
- IOS适用于更短的扫描范围,例如5个单位范围内的固定假肢.
- 与当前的IOS技术相比,传统的印记在全弧牙部扫描中保持了更高的准确性.

01:15Distance Corrections
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...
01:10Design Example: Measuring Distance Between Two Points with Obstructions
When measuring distances in areas with physical obstructions, such as a lake in a field, surveyors must employ techniques to calculate accurate lengths without direct line measurements. One effective method is the offset technique, which allows for precise distance estimation over inaccessible stretches.In this scenario, a surveyor must measure a side of an area that crosses a lake. Since the measuring tape cannot span the lake, the surveyor begins by establishing a baseline that aligns with...
