患有III级骨缺陷的成年人中侧侧 sutures较薄,上基较窄. 底宽度和口腔平面角与口腔中间接的厚度相关.
科学领域:
- 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
- 放射性分析 放射性分析
背景情况:
- 在 ортодонтических程序中,部接骨厚度 (BTMS) 是至关重要的.
- 了解BTMS在不同斜面面部模式中的变化是必不可少的.
- 圆束计算断层扫描 (CBCT) 能够对面结构进行详细的分析.
研究的目的:
- 为了研究成年人中侧面 (BTMS) 的骨厚度,这些成年人有不同的斜面面部图案.
- 探索影响BTMS的因素,包括底宽度,ANS-PNS长度和PP-IP角度.
- 为了比较骨I,II和III类异常面部模式之间的BTMS.
主要方法:
- 分析了260名成年人的CBCT图像.
- 试验对象被分为骨类I,II和III组.
- 测量包括BTMS (分为H-前,H-中,H-末),大底宽度,ANS-PNS长度和PP-IP角度.
主要成果:
- 与I类相比,III类骨受试者表现出明显较薄的BTMS,特别是在H-中间和H-末端部分.
- 与I类相比,III类受试者还表现出更窄的上底宽和更短的ANS-PNS长度.
- BTMS与上底宽度,ANS-PNS长度和PP-IP角度显示出正相关性.
结论:
- 患有骨III类异常缺陷的成年人可能呈现出更薄的中侧 sutures和更窄的底.
- 底宽度和PP-IP角度似乎与BTMS正相关.
- 这些发现对正义牙科治疗计划有意义,特别是关于 palatal 扩张.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Cranial Bones: Lateral View
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...

Cranial Bones: Superior and Posterior View
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,...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
