A visual aid in the form of a lined transparent plastic screen is attached to an earbow type of facebow and placed on the face. The screen can be adjusted to several horizontal tilts from the horizontal aspect in a clockwise or counterclockwise direction. The screen helps the dentist visualize horizontal and vertical facial characteristics that facilitate alignment of anterior restorations. This information can be sent to the laboratory, which can interpret the data with a smaller version of the adjustable screen.
一种带刻度的透明塑料屏幕形式的视觉辅助工具附在耳弓式面弓上并放置在面部。该屏幕可从水平方向沿顺时针或逆时针方向调整到几个水平倾斜角度。该屏幕有助于牙医观察水平和垂直面部特征，便于前牙修复体的排列。此信息可发送至实验室，实验室可以使用可调节屏幕的较小版本来解读数据。
