A partial dental arch is provided with dentin material and with cutting material and a boundary area therebetween. It includes a primary-position tooth region and additional tooth regions which are arranged more distally. A wavy structure of the boundary area is provided whose amplitude&#x2014;when viewed in the distal direction&#x2014;decreases in at least one section of the mesial-distal and/or occlusal-gingival extension, in particular with regard to the occlusal-gingival direction.

Partial dental arch and method for manufacturing a partial arch

A dental multi-colored milling blank having at least two layers (), a transition zone, where material from both layers is present. In the transition zone, a transition geometry exists that extends three-dimensionally. The transition geometry comprises round surfaces facing towards both directions of extension of the layers.

The invention relates to a tooth made of ceramics, a composite or plastic, which is produced in a mold, said tooth having a basal surface () that comprises a trough (). The especially elliptical or circular trough () is adapted to the basal surface () and has a trough edge () which extends at least partially in an angle of more than 45 degrees, in particular more than 60 degrees or 70 degrees, with respect to the adjacent basal surface ().
