A prosthetic tooth for a denture comprises a lingual or palatal surface, an opposing vestibular surface, opposing proximal surfaces, an incisal or occlusal surface and an opposing apical surface, wherein a pocket or slot is defined in the apical surface. The pocket or slot makes it easier to determine whether the tooth is positioned correctly when the tooth is aligned with a denture plate and assists with determining whether the tooth has twisted or tilted.

Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.

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.

Glass ceramics having SiO.sub.2 as main crystal phase and precursors thereof are described which are characterized by very good mechanical and optical properties and in particular can be used as restoration material in dentistry.

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.

A tool for forming a dental restoration includes a mold body configured to provide a customized fit with at least one tooth of a patient. In some examples, the mold body defines an aperture configured to align with a portion of a surface of a tooth. The aperture is sufficiently large to allow placement and flow of restorative material over the desired portion of the surface of the tooth to be restored. The mold body is configured to combine with the at least one tooth of the patient to define a mold cavity encompassing at least a portion of desired tooth structure of the tooth to be restored.

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.

Disclosed is a method for manufacture of a removable dental prosthesis by moulding, the method including: digital modelling of a prosthesis model; a step of producing a mould including a lower half-shell corresponding to a tooth part of the prosthesis and an upper half-shell corresponding to a gum part of the prosthesis, the two half-shells being able to be joined together by affixing one to the other, thereby forming an impression of the prosthesis, the step including digital modelling of a model of the mould, followed by additive manufacture of at least the lower half-shell, and a step of producing the prosthesis, the step including in succession at least one provision of at least one artificial tooth, positioning of the artificial tooth in a seat of the lower half-shell, assembling the mould and pouring a filler material into the mould. Also disclosed is a prosthesis obtained by this method.

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.

The invention relates to a method for processing a dental material (28), in particular pressing and curing a dental material, by means of—a molding insert (30) that has a pre-pressing area (22) which adjoins a molding area (14, 16), wherein the pre-pressing area (22) is designed to receive the dental material (28), and—a pressing furnace with a firing chamber (10) for receiving the molding insert (30). The method has the following steps: —introducing the dental material (28) into the pre-pressing chamber (22); —heating the firing chamber (10), in which the molding insert (30) is located, pressing the dental material (28) towards the molding area (14, 16) using a pressing punch (26) by applying a force onto the pressing punch (26) during a first processing phase, wherein the pressing punch (26) is moved, and the pressing punch speed is detected as a speed profile dependent on the time; and adjusting the firing chamber (10), in particular cooling the firing chamber to a second temperature, during a second processing phase starting at a point in time at which the detected speed profile matches a first speed profile without reducing the force applied to the pressing punch (26).
