    • The present disclosure provides for a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer (102) of a first hard restorative material having a first translucency and a first shade, a second layer (104) of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true: the first translucency is different from the second translucency, the first shade is different from the second shade. The first layer (102) and the second layer (104) form a first interface having a first curve (112) across a first plane of symmetry (114) of the dental mill blank, where the first curve (112) has a different from zero curvature; and a first straight line (122) along the entire length of a second plane (118) of the dental mill blank, the second plane (118) being orthogonal to the first plane of symmetry (114).
    • 本公开内容提供了一种牙科磨机坯料和形成牙科磨粉机的方法。 牙科磨坊坯料包括具有第一半透明度的第一硬修复材料的第一层(102)和第一遮蔽物,具有第二半透明度和第二遮蔽物的第二硬修复材料的第二层(104),其中至少 以下之一是真实的:第一个半透明度与第二个半透明度不同,第一个阴影不同于第二个阴影。 第一层(102)和第二层(104)形成第一界面,该第一界面具有穿过牙磨机坯料的第一对称平面(114)的第一曲线(112),其中第一曲线(112)具有不同于 零曲率; 以及沿所述牙粉磨坯的第二平面(118)的整个长度的第一直线(122),所述第二平面(118)正交于所述第一对称平面(114)。
