Regardless of its anatomic shape, an edentulous arch is formed by two types of mucosa, different in both nature and behavior. This is why the impression of such a complex requires two distinct steps with two different modeling materials with different consistency. The first step is the border molding of the mucosal reflexion zone with a silicone of medium viscosity, placed on the borders of the custom tray. The second step is the static impression of the inner part of the denture, with a fluid or very fluid silicone.
无论其解剖形态如何,无牙颌由两种性质和行为不同的黏膜构成。这就是为什么对如此复杂的区域取印模需要分两个不同的步骤,使用两种不同稠度的模型材料。第一步是用中等黏度的硅橡胶对黏膜反折区进行边缘整塑,将其置于定制托盘的边缘。第二步是用流动性大或非常大的硅橡胶对义齿内部进行静态印模。
