概括
我们比较了两种骨载大扩张装置,即C扩展器和ATOZ扩展器. 这两种设备都扩大了头骨和周,但ATOZ扩展器与C扩展器相比,对前肌有明显的影响.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 面生物学 面生物学
- 生物材料工程 生物材料工程
背景情况:
- 迷你螺杆辅助大扩张对于化中侧 sutures 的患者至关重要.
- 了解不同的骨载器件对头骨和周的影响,对于治疗规划至关重要.
研究的目的:
- 评估和比较两种骨载大扩张器件 (C-扩展器和ATOZ扩展器) 对头骨和周的作用.
- 在横向大扩张之前和之后,使用圆束计算机断层扫描 (CBCT) 分析接宽度的变化.
主要方法:
- 81名患者使用C扩展器 (n=44) 或ATOZ扩展器 (n=37) 进行了上扩张.
- 在扩张前和后 (T0和T1) 获得CBCT扫描.
- 测量了10个环 sutures的宽度在 sagittal,冠状和轴平面;统计分析使用威尔科克森的签名级别测试 (P <0.05).
主要成果:
- 在这两组中都观察到前鼻,前,胸,鼻,鼻,内,胸间和中部接宽度的显著增加.
- 在C-扩展器组显示降低了frontozygomatic,zygomaticomaxillary和temporozygomatic接的宽度,而ATOZ扩展器组显示增加了frontozygomatic接的宽度.

01:22Sutures of the Skull
6.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...

01:27Cranial Bones: Lateral View
2.0K
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...

01:08Overview of the Skull
4.3K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
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...

01:29Bone Formation by Intramembranous Ossification
5.5K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...
