概括
在提取的情况下,清晰对齐器 (CA) 处理可能会导致意外的切肢运动. 积极的狗倾斜策略,而不是编程的身体运动,最大限度地减少这些不良影响,并改善CA适应.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 生物材料科学 生物材料科学
- 牙科机械 牙科机械
背景情况:
- 清晰对齐器 (CA) 越来越受欢迎,但在提取情况下存在挑战,包括"过山车效应".
- 以前的研究忽略了牙对对齐器的对抗力,只关注对齐器所施加的力.
- 了解狗远端运动通过牙对齐器相互作用对切口的影响至关重要.
研究的目的:
- 为了分析不同的狗远端运动模式如何通过牙对齐器力反影响切口位置.
- 评估各种附着设计和运动策略在提取病例的清晰对齐器治疗中的有效性.
主要方法:
- 开发了一个3D有限元模型,包括牙,牙周带,附件和CA.
- 模拟了三种狗的远距离运动模式:身体运动与垂直矩形附件,身体运动与优化附件,和远距离倾斜与垂直矩形附件.
- 利用代建模来分析牙移位,接触应力和对齐器变形.
主要成果:
- 所有模拟的狗的远部运动都导致了顶倾斜,不论是被编程的身体运动.
- 试图体内狗肢运动的小组对切口器的语言压力增加,导致更大的口腔位移和旋转.
- 狗的远端倾斜 (3组) 显示出更好的对齐器适应性和减少了不良的切肢运动.
结论:
- 通过当前的附件来实现身体犬的脱是不可行的;倾斜是不可避免的.
- 编程的身体狗的运动诱导清晰的对齐器变形和不必要的切口运动.
- 在提取的情况下,建议优先考虑基于倾斜的犬类运动策略,随后进行根部控制,以获得清晰的对齐器治疗.

Design Example: Alignment of a Road Line Using GIS
350
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Impression Management Techniques III: Aligning Actions
131
Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...

Teeth
1.8K
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...

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

Periodic Classification of the Elements
59.0K
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...
