概括
对于完整的牙弧扫描,传统的印记仍然是最精确的. 虽然口腔内扫描仪 (IOS) 的精度有所不同,但它们的完整弧形扫描通常保持在100微米以下,这表明技术正在改进.
科学领域:
- 牙科 牙科是指牙科的专业.
- 数字牙科数字牙科
- 牙科技术 牙科技术
背景情况:
- 口腔内扫描系统 (IOS) 正在越来越多地取代传统的牙科工作流程.
- 从IOS的完整的门扫描的准确性仍然是一个重大挑战.
研究的目的:
- 评估和比较六种当前口内扫描仪 (IOS) 的精度和真实性.
- 用传统的高精度打印技术作为控制器来评估完整的弧度记录准确性.
主要方法:
- 十名参与者使用六种IOS和一种常规印象 (CONV) 技术进行了三次完整的门扫描.
- 通过集团内部比较来评估准确性;通过将IOS数据与CONV数据进行比较来计算准确性.
- 统计分析包括Welch ANOVA和Games-Howell的后期测试.
主要成果:
- 传统的印记 (CONV) 显示的精度明显高 (21±4μm) 比所有IOSs.
- 在IOS中,精度各不相同,而Emerald S (EME) 显示的精度最低 (82±38μm).
- 准确度值在41 ±10μm (Primescan) 到96 ±29μm (EME) 之间,扫描仪组之间发现了显著差异.
结论:
- 传统的高精度材料仍然是完整门记录的标准.
- 对于完整的门扫描,IOS之间存在显著的精度差异.
- 尽管存在差异,但测试的IOS全弧扫描的精度不超过100微米.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
