概括
内口扫描仪 (IOSs) 显示了对正牙扫描的临床可接受的准确性. 然而,随着牙门拥挤的增加,扫描精度会降低,特别是在大门中.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 牙科技术 牙科技术
- 生物医学工程 生物医学工程
背景情况:
- 口腔内扫描仪 (IOSs) 越来越多地被采用在正牙科.
- 评估IOS准确性与不同的牙拥挤是至关重要的.
研究的目的:
- 评估牙门拥挤严重程度对IOS扫描精度的影响.
- 为了比较轻度,中度和严重拥挤水平的扫描精度.
主要方法:
- 使用IOS和桌面扫描仪扫描了具有明显拥挤程度 (轻度,中度,严重) 的三个牙科模型.
- 使用CAD软件生成和分析立体石版文件,以量化偏差.
- 统计分析比较了尾和下弓中不同拥挤水平之间的偏差.
主要成果:
- 大门:随着拥挤的严重程度 (严重>轻微>中等) 的增加,偏差增加.
- 门:偏差的顺序是严重>中度>轻度.
- 在大门 (P < 0.001) 中发现了显著的偏差,但在下门 (P = 0.669) 中没有.
结论:
- 对于所有拥挤级别,IOS扫描的真实性保持在临床上可接受的范围内.
- 增加牙拥挤通常会降低扫描精度.
- 临床医生在使用IOS用于严重拥挤的门时,应注意潜在的偏差,特别是在部区域.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:26Assessment 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.
