概括
尾闭塞往往是由于发育不发达,而不是相同的缺陷. 这项研究使用3D头骨模板来分类口,发现低发育最常见的面部类型是中等发育型和发育型.
科学领域:
- 牙科 牙科是指牙科的专业.
- 矯正牙科 矯正牙科是一種矯正牙科.
- 头骨面部解剖学 头骨面部解剖学
背景情况:
- 尾闭塞位诊断缺乏完整的分类方法.
- 区分双边相等断层和单边过度/欠发达是很有挑战性的.
- 一个新的平均3D头骨模板被提议用于分类关口腔关口.
研究的目的:
- 引入和验证一个平均的3D头骨模板来分类关口角.
- 分析不同口径分类 (过度发达,欠发达,相同缺陷) 与面部类型相关的流行情况.
- 为了研究面部形态与关闭口口腔的模式之间的关联.
主要方法:
- 60名成年患者被分为中等性 (n=30) 和轻性 (n=30) 的面部类型.
- 平均3D头骨模型被对齐并叠加到患者头骨模型上,使用7对解剖学地标.
- 尾闭塞斜率是通过测量从第一个头尖端到弗兰克福水平平面的垂直距离来分析的.
主要成果:
- 在中等发育症患者中,发育不良 (B类) 是最常见的 (40%),其次是过度发育 (A类,27%) 和相同缺陷 (C类,33%).
- 在白血病患者中,欠发育 (B类) 也是最常见的 (50%),其次是过度发育 (A类,43%) 和平等缺陷 (C类,7%).
- 统计分析证实了面部类型和观察到的口角分类之间存在显著的关联.
结论:
- 部发育不良是比以前认为的更常见的闭合性的原因.
- 曲模式的患病率在美索普罗索普和莱普托普罗索普面部类型之间有显著差异.
- 平均3D骨面部模型是诊断大闭口腔位的有效工具.

01:14Cranial Bones: Superior and Posterior View
7.6K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

6.8K
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...
