概括
近接接触损失 (PCL) 影响了超过一半的长期牙科植入物,特别是在 mesial 侧. 邻近牙的牙周健康状况不佳和牙区域的位置不佳增加了PCL的风险.
科学领域:
- 牙科植入物学 牙科植入物学
- 牙周病学 牙周病学
- 牙修复 牙修复 牙修复 牙修复 牙修复
背景情况:
- 长期牙植入成功率很高,但可能会出现并发症,如近接接触损失 (PCL).
- 植入物和相邻牙之间的PCL可以对这两个结构产生负面影响.
- 了解PCL患病率和风险因素对于长期的植入物维护至关重要.
研究的目的:
- 确定在韩国患者中PCL的患病率,这些患者的牙植入物已运行超过10年.
- 确定与PCL相关的患者,植入物和牙相关的因素.
- 调查牙周病史对PCL的影响.
主要方法:
- 评估了来自101名患者的142个固定牙植入物 (运行超过10年) 和188颗相邻的牙.
- 评估患者,植入物和牙因素,包括牙周状况.
- 使用奇平方和费舍尔精确测试进行统计分析 (显著程度P<0.05).
主要成果:
- 总体PCL发病率为53.7%,其中较高的发病率在 mesial (65.6%) 和 distal (28.3%) 方面.
- 植入物在部部位的放置与PCL有显著的关联.
- 邻近的牙因素,如斑块,移动性,在探测时出血,以及深口袋 (≥4mm) 与PCL相关.
结论:
- 长达十多年的牙科植入物显示PCL的高发病率 (>50%),每月更常见.
- 后部植入物定位和邻近牙的牙周健康状况受损是PCL的重要风险因素.
- 这些发现强调了监测邻近牙牙周健康状况对于长期植入成功的重要性.

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 and...

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.
