概括

三个口腔内扫描仪 (IOS) 显示出临床上可接受的牙假体准确性. 虽然扫描器的精度因制备类型而异,但所有IOS都适合嵌入式,在线式和桥式.

科学领域:

数字牙科
牙科材料科学
生物医学工程

背景情况:

牙内部扫描仪 (IOS) 正在彻底改变数字牙科,
评估IOS的实验室准确性对于确保牙科修复的临床成功至关重要.

研究的目的:

为了比较三个内口扫描仪 (IOS) 的实验室准确性,用于内置,内置和三单元固定部分假牙制剂.
使用实验室扫描仪进行准确性评估,建立参考标准.

主要方法:

三种类型的牙制剂 (内置,内置,三单元FPD) 进行了3D打印.
使用三个IOS (TRIOS4,I500,COMFORT+) 和一个实验室扫描仪 (参考) 进行扫描.
使用3D检查软件评估了准确性 (真实性和精度).

主要成果:

在IOS类型中没有发现真实性的显著差异.
所有IOS的三单元FPD的真实性都低于内置和在线.
IOS的精度差异很大,特定的扫描仪对某些制剂的性能更好.

结论:

经过测试的IOS (TRIOS,I500,COMFORT+) 显示出临床上可以接受的实验室准确性.
这些IOS适用于制造各种牙假肢,从内嵌到皇冠和桥梁.

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
