概括
在清晰对齐器疗法 (CAT) 后,开放的牙接口 (OGE) 是常见的,特别是在牙提取时. OGE与骨损失和其他并发症有关,需要在正义牙科治疗期间仔细监测.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 牙周病学 牙周病学
- 牙科成像 牙科成像 牙科成像
背景情况:
- 清晰对齐器疗法 (CAT) 在成人牙科中很受欢迎.
- 开放的牙包裹 (OGE) 或"黑色三角形"可能会影响美学和口腔健康.
- CAT,OGE和牙周健康之间的关系需要进一步研究.
研究的目的:
- 确定在接受CAT的成年患者中OGE的患病率和危险因素.
- 分析OGE与解剖学指标,牙运动和骨损失之间的关联.
- 为在CAT期间管理OGE提供临床指导.
主要方法:
- 一组由518名接受CAT治疗的成年患者组成的队列被评估了OGE患病率.
- 横向头脑电图和CBCT扫描用于评估281名患者的解剖学指标.
- 分析了186名非拔牙患者的牙移动与OGE之间的相关性.
主要成果:
- OGE的患病率很高,与拔牙有显著的关联,在单次拔下切口的情况下,更高的患病率.

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.

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...
