概括

虚拟支架移除 (VBR) 保持器在六个月内提供了与传统方法相比的正牙保持. 这种创新技术显著减少了患者和临床医生坐在椅子上的时间.

科学领域:

矯正牙科矯正牙科是一種矯正牙科.
牙科材料科学牙科材料科学

背景情况:

ортодонтическое治疗需要有效的保留,以保持结果.
传统的保持器制造可能耗时,需要物理模型.

研究的目的:

引入和评估虚拟支架移除 (VBR) 技术,用于制造热塑性保持器.
通过使用多维框架,比较VBR保持器与常规保持器的保持效率.

主要方法:

38名患者被随机分配到VBR保持器和常规保持器组.
在六个月内通过测量表面偏差 (RMS),形变化和六维牙运动来评估保留.
结果在各组之间和临床可接受限值 (CALs) 之间进行了比较.

主要成果:

在VBR和常规保持器之间没有发现表面偏差或形变化的显著差异,所有都低于CALs.
虽然在VBR组中注意到一些统计学上显著的牙运动 (例如扭矩,翻译,角度),但所有这些都低于CALs.
与传统方法相比,VBR方法显著减少了患者访问的持续时间.

结论:

在六个月的时间内,VBR保持器的保持效率与传统的保持器相比相当.
该VBR技术提供了一种高效和节省时间的方法,用于正牙保留,适合常规的临床实践.

In Vitro Drug Dissolution: Alternative Methods

In Vitro Drug Dissolution: Alternative Methods

Alternative drug dissolution methods include the rotating bottle, intrinsic dissolution test, peristalsis, and the Franz diffusion cell method. The rotating bottle method involves meticulously rotating tightly capped controlled-release beads in a temperature-controlled bath. Periodic decanting of samples allows for residue assay, followed by refilling with fresh medium and testing at various pH levels to emulate the gastrointestinal tract conditions.In contrast, the intrinsic dissolution test...
