概括

使用临时骨架固定装置 (TSADs) 的清晰对齐器治疗 (CAT) 显示出有限的尾大脱稳效率. 虽然TSADs没有显著改善脱,但有助于身体运动和牙的侵入.

科学领域:

矯正牙科矯正牙科是一種矯正牙科.
牙科技术牙科技术

背景情况:

清晰对齐器疗法 (CAT) 提供了有限的尾大骨脱稳定,往往导致不良的冠状倾斜.
将CAT与临时骨架固定装置 (TSAD) 结合起来是一个提议的增强,但缺乏详细的评估.

研究的目的:

为了评估结合清晰对齐器疗法与用于大骨脱稳的低体临时骨架 anchorage 装置的疗效.
通过使用圆束计算断层扫描 (CBCT) 和口腔内扫描,将实现的牙运动与规定的运动进行比较.

主要方法:

对成年患者进行了回顾性研究,这些患者接受了CAT和下皮TSAD治疗.
治疗前和治疗后CBCT图像和口腔内扫描的分析.
实现与编程的上大移动的比较.

主要成果:

已经实现了骨脱 (大约. 1毫米) 显著小于规定的 (大约1毫米). 3 毫米). 这是一个很大的问题.
发生了有限的远端冠状倾斜和 mesial-out 旋转.
观察到明显的口腔扩张和尾牙的侵入.
在处方的远端运动和脱效果之间存在负相关性.

结论:

临时骨固定装置在清晰对齐器治疗下并没有显著提高尾干脱稳效率.
TSADs有助于更多的身体运动和尾牙的侵入.

Fractures: Bone Repair

Fractures: 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...
