概括

ортодонтическое治疗可以改变牙的门宽度,可能导致复发. 治疗期间门宽度的适度增加通常是长期稳定的,但较大的扩张与治疗后复发的增加有关.

科学领域:

矯正牙科矯正牙科是一種矯正牙科.
牙弧的尺寸牙弧的尺寸
偶稳定性偶稳定性

背景情况:

牙弧宽度是平衡闭塞的关键因素,但在正义牙科治疗期间经常被修改.
这些修改可能导致正牙后复发,影响长期稳定性.

研究的目的:

用固定器件进行正牙治疗后,评估牙宽度的长期变化.
为了确定牙提取对门宽度变化的稳定性的影响.

主要方法:

对年轻患者 (<18岁) 进行了回顾性纵向研究,这些患者接受了0.018英寸插槽边缘固定装置的治疗.
在治疗前,治疗后和平均在治疗后7年期间,数字测量了大/下内,口腔和口腔间的宽度.
使用回归建模进行统计分析,并对提取对稳定性的影响进行亚样本分析.

主要成果:

所有牙弧宽度在治疗期间都增加,抽取和非抽取组之间存在显著差异.
没有提取的病例在7年后出现了显著的间宽度复发;间和间宽度保持稳定.
治疗期间牙弧宽度增加与治疗后复发有关,每增加1毫米的复发幅度为0.20-0.34毫米.

结论:

在正治疗期间,牙弧宽度的适度增加表明了良好的长期稳定性.
治疗期间门扩张较大与治疗后复发的发病率较高有关.

Teeth

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...
