概括
在非提取固定正牙治疗 (OT) 中粘合第二牙显著改善了治疗结果,根据美国正牙科学会造放射评价 (C-R-Eval) 评分进行测量. 这种方法在不延长治疗时间的情况下提高了结果,尽管紧急诊所的访问可能会增加.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 牙科研究 牙科研究
- 临床牙科 临床牙科
背景情况:
- 没有提取的固定正牙治疗 (OT) 是纠正缺陷的常见方法.
- 第二结在优化OT结果中的作用仍然是一个研究领域.
- 在临床实践中,使用标准化的客观措施评估治疗效果至关重要.
研究的目的:
- 为了比较非提取的正牙治疗结果,固定OT与没有第二关节结合.
- 为了评估治疗的有效性,使用美国矯正牙科委员会造放射图评估 (C-R-Eval) 评分.
- 分析二次结果,包括斯皮曲线,超咬,切口下平面角,治疗持续时间和急诊.
主要方法:
- 一项比较性研究,涉及患有I类或轻度II/III类坏闭症的青少年,接受非提取固定的OT.
- 分析了两个组:具有第二牙结合的和没有第二牙结合的组.
- 结果使用治疗前后记录进行评估,包括数字模型,脑图和C-R-Eval得分.
主要成果:
- 与没有结合的组相比,带有结合的第二牙的组获得了明显更高的CR-Eval得分 (更好的结果) (17.70对25.25,P <.001).
- 在Spee曲线的平均变化,过度咬伤,切口下平面角度或治疗持续时间之间没有观察到显著差异.
- 结合群体的急诊次数平均显著增加 (3.3对1.9,P<.001).
结论:
- 在非提取固定的正牙治疗中粘合第二牙显著提高了C-R-Eval评估的整体治疗结果.
- 这种改善的结果可以在没有增加整体治疗持续时间的情况下实现.
- 虽然急诊次数可能会增加,但对治疗质量的好处证明这种做法是合理的.

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 molecular orbital theory describes the distribution of electrons in molecules in a manner similar to the distribution of electrons in atomic orbitals. The region of space in which a valence electron in a molecule is likely to be found is called a molecular orbital. Mathematically, the linear combination of atomic orbitals (LCAO) generates molecular orbitals. Combinations of in-phase atomic orbital wave functions result in regions with a high probability of electron density, while...

Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons...

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
