概括

前牙的结合角 (CA) 在不同的缺陷中有显著的变化,在II类第2部分观察到的CA最高. 牙通常比大牙呈现较低的CA,特别是在I类缺陷中.

科学领域:

矯正牙科矯正牙科是一種矯正牙科.
牙科解剖学牙科解剖学
放射学放射学是一门学科.

背景情况:

角 (CA) 对于评估前牙的冠根角是必不可少的,有助于诊断和治疗规划.
圆束计算断层扫描 (CBCT) 能够精确评估牙角.
了解CA变异跨 malocclusions 对于有效的正义牙科干预至关重要.

研究的目的:

为了评估大和下弧中所有前牙的结合角 (CA).
为了比较不同类型的斜部缺陷 (I,II/1,II/2,III类) 的CA测量结果.
为了研究CA的潜在的性别和侧面 (右与左) 差异.

主要方法:

这是一项涉及80名正牙前患者的横截面研究.
根据牙骨缺陷 (I,II/1,II/2,III类) 患者被分为四组.
使用CBCT测量了两下所有前牙的CA;数据被统计分析.

主要成果:

统计学上显著的CA差异被发现,在所有前牙跨 malocclusion 组 (p<0.05).
对于所有前牙,在II类二级二级缺陷组中始终观察到最高的平均CA.
在CA中没有发现显著的性别或副作用差异 (p>0.05).

结论:

二级二级二级恶性闭塞与前牙的最高结合角 (CA) 有关.
牙通常比大牙具有较低的CA.
最低的CA值记录在下牙在I类缺陷中.

Cranial Bones: Lateral View

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Deformations in a Transverse Cross Section

Deformations in a Transverse Cross Section

When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...
