概括
在面罩疗法中,用小板固定骨,与牙固定相比,大和中脸的提升显著增加. 这种方法促进了尾骨的更大前进运动,并增加了尾骨的横向尺寸.
科学领域:
- 矯正牙醫和牙臉整形醫學
- 头骨面部的发展
- 在正牙科中使用生物材料.
背景情况:
- 面罩治疗对于纠正III类缺陷的治疗至关重要,主要是通过推进面部中部.
- 传统的牙承载固用于快速扩张和面罩 (RME/FM) 在实现最佳骨运动方面存在局限性.
- 使用迷你板的骨 anchorage 提供了一个潜在的更稳定和有效的替代方案,用于骨科力应用.
研究的目的:
- 为了比较面罩治疗与骨架 (迷你板) 固与牙载固对尾后部结构的影响.
- 通过使用形光束计算断层扫描 (CBCT) 来评估尾前进的变化,pterygomaxillary的移动性和横向尺寸.
主要方法:
- 一项回顾性研究分析了接受面罩治疗的20名患者的CBCT图像.
- 患者被分为两个组:迷你板/FM (骨架固定) 和RME/FM (牙固定).
- 在治疗前和治疗后评估尾后部结构,以检测骨变化.
主要成果:
- 迷你板/FM组表现出比RME/FM组显著更大的上和中面推进 (p < .05).
- 在迷你板/FM组中,形状部的进展大约是微型板/FM组的三倍.
- 迷你板/FM组在后部和上部大部的横向尺寸增加 (p < .05).
结论:
- 用骨架 anchorage 进行面罩疗法,可使得皮质接线的前进运动变得更大.
- 骨固定导致大和中脸的提升,与牙固定相比.
- 迷你板 anchorage 提供对大骨变化的优越控制,包括横向扩张.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:15Teeth
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 and...
