The present invention relates to a method for fabricating a dental restoration, comprising the steps of rendering (S101) a first digital tooth model with a first material combination for generating a first actual data set representing the optical properties of the first digital tooth model; determining (S102) a first deviation between a target data set and the first actual data set; rendering (S103) a second digital tooth model based on a second combination of materials to generate a second actual data set representing the optical properties of the second digital tooth model; determining (S104) a second deviation between the target data set and the second actual data set; and fabricating (S105) the dental restoration based on the first digital tooth model when the first deviation is less than the second deviation and fabricating the dental restoration based on the second digital tooth model when the second deviation is less than the first deviation.

A multilayer crown includes an outer layer and an inner layer. The outer layer may be formed of a first polymeric material. The inner layer may be formed of a second polymeric material that is different from the first polymeric material. The inner layer may be arranged to contact a tooth so that the inner layer is located between the outer layer and the tooth.

A one-piece or multi-piece prosthesis blank for manufacturing a dental prosthesis. The blank is constructed from a gum-colored material and a tooth-colored material. It is characterized by being connected to each other at connecting surfaces, having an interface between the gum-colored and tooth-colored materials. This interface, when viewed along the connecting surfaces has an undulating shape and viewed in the vestibular direction has a radial shape. In order to finish the dental prosthesis, a CAD/CAM device determines the exact course of a gingival line, based on patient-specific data, and produces the prosthesis.

An offset gingival overlay denture is provided. An offset gingival overlay denture may include a denture core and a gingival overlay extending over a portion of the denture core. The denture core may provide support to artificial dentition structures, such as teeth, and a gingival overlay may simulate natural mucosa, such as gum tissue.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

A method for forming a multi-layer blank of a ceramic material including the steps of: providing a mold that includes at least one side wall surrounding a lower press plunger to form a cavity therebetween, wherein the lower press plunger has a movable pin; filling into the mold a first ceramic material; extending the movable pin from an upper surface of the lower press plunger and into the cavity; pressing a first upper press plunger against the first ceramic material so that a first open cavity is formed while at least a portion of the first upper press plunger is in contact with the movable pin to maintain the through-hole through the first layer; filling into the mold a second ceramic material of a different composition; extending the movable pin from an upper surface of the first layer and into the first open cavity; and pressing a second upper press plunger against the second layer so that a second open cavity is formed in communication with the through-hole that extends through the first and second layers to form the blank.

The invention relates to a blank from a ceramic material, wherein at least two layers of ceramic material of different compositions are filled into a die layer-by-layer and after filling of the layers they are then pressed and sintered, wherein after filling of a first layer this is structured on its surface in such a way that the first layer, viewed across its surface, differs in its height from region to region, and then a layer with a composition that differs from the first layer is filled as a second layer into the mold.
