科学领域:
- 牙科 牙科是指牙科的专业.
- 矯正牙科 矯正牙科是一種矯正牙科.
- 口腔和牙面部外科手术
背景情况:
- 第三个牙提取后面部减肥是对正牙患者的一个担忧.
- 了解软硬组织体积变化对于治疗规划至关重要.
研究的目的:
- 为了研究面部软硬组织的体积变化后的第三骨提取.
- 建立一个可重复的临床方案来评估这些变化.
主要方法:
- 一项试点研究涉及23名成年人接受ipsilateral第三牙提取.
- 结构光扫描和CBCT成像用于体积测量.
- 开发了一种新的投影方法来量化软组织体积变化 (STVC) 和硬组织体积变化 (HTVC).
主要成果:
- 在提取方面,硬组织体积减少了-2.33 ± 0.46毫升.
- 软组织体积在3个月后暂时下降,但在6个月后恢复到基线.
- 开发的STVC测量方法显示出出色的重复性 (ICC>0.95).
结论:
- 第三骨提取导致硬组织减少,但长期软组织体积没有显著变化.
- 拟议的STVC测量协议是可靠的,并且适用于正统牙科和骨科的其他面部区域.
- 建议进行进一步的大规模研究以验证这些发现.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

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...
