概括

全范围动态关节有效地防止固定后部修复中的动态干扰接触. 这种方法避免了针对患者的特定设置,简化了CAD/CAM修复的设计过程.

科学领域:

牙科假牙科牙科假牙科
计算机辅助设计 (CAD)
闭合分析是指闭合分析.

背景情况:

关于在假牙科中使用面弓和单独关节器设置的必要性存在争议.
简单的方法经常与固定后部修复的先进技术进行比较.

研究的目的:

评估新的算法关节器概念,作为避免动态干扰接触的替代方案.
评估这些概念对固定后部修复的闭合形态的影响.

主要方法:

从椅子旁的CAD数据库中选择了50例患者病例 (61次恢复).
在CAD软件中应用静态闭塞,平均关节和全范围动态关节.
使用监控软件将动态接触点视觉和指标进行比较.

主要成果:

与静态或平均关节相比,全范围动态关节显著减少了动态干扰接触 (P < 0.001).
相互透的接触点的虚拟研磨导致恢复表面的形态变化最小.

结论:

全范围动态关节是设计固定后部修复的可行方法.
这种方法有效地避免了动态干扰接触,而不需要患者特定的参数.

关键词:

在CAD/CAM中使用.平均关节的形成面对面的弓形面对面的弓形全系列的动态关节.虚拟的关节是虚拟的关节.虚拟功能生成路径 (FGP)

Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
