A blank for producing dental prostheses by particularly material-removing processing comprises a tooth element and a jaw element. These elements are preferably differently colored layers of a blank produced from the same material. In order to cover a dividing line between the differently colored regions, a gum element is arranged especially in a recess of the finished dental prosthesis.

A polymerizable adhesive composition containing an olefinically functionalized carbohydrate, a polymerizable liquid monomer, and optionally at least one polymerization initiator or initiator system is described. The adhesive composition is particularly well suited for adhering plastic components as well as is preferably provided with sufficiently long processing time for adhering artificial teeth on denture bases. The viscosity of the adhesive composition may be adjusted to the respected processing conditions.

A method for manufacturing a dental restoration part according to patient-specific requirements is provided, which dental restoration part comprises a prosthesis base, wherein the prosthesis base carries at least one prefabricated artificial tooth, in particular a large number of prefabricated artificial teeth.

It is also intended for the prosthesis base to have a surface on the side facing away from the prefabricated artificial teeth, i.e. on the side opposite thereof, and a three-dimensional layer of material to be applied to this surface of the prosthesis base using a three-dimensional additive method, by which the prosthesis base will be fabricated according to the patient-specific specifications.

The invention relates for producing permanent dentures without using any implants (screws) on the gum or using glue but using the vacuum of suction cells (suckers), between the natural gum and dentures, but using flexible thin plastic (approved by FDA) sheath between the gum and the dentures using suckers (similar to octopus) made on upper and lower surfaces of the sheath the upper sheath surface will have the same shape of the normal denture lower surface, similarly the lower sheath surface will have the same shape of the gum, the shape of the plastic sheath will always have the same shape of the gypsum modeled cast at the dentist clinic, for the gum surface, all the suckers will be (squeezed) pressed and create vacuum to hold the dentures to the gum and the dentures.

A method for creating a digital model of a denture for a patient, where the denture includes a gingival part and artificial teeth, includes obtaining digital models of artificial teeth representing the artificial teeth; obtaining a 3D scan comprising a digital representation of at least part of the patient's existing gingiva; digitally modeling a gingival part of the digital model of the denture using the 3D scan and the digital artificial teeth; digitally determining a first offset defining a first thickness of a first portion of the gingival part of the digital model of the denture that extends from the digital representation of the at least part of the patient's existing gingiva; and digitally determining a second offset defining a second thickness of a second portion of the gingival part of the digital model of the denture that extends from the digital artificial teeth.

Photo-curable compositions for artificial teeth and denture base and a method for manufacturing denture by a three-dimensional printing system are provided. The compositions include photo-curable organic compounds, surface modified nano-sized inorganic filler, photo-initiator, colorant, and stabilizer. The composition is in a viscous liquid state having 1,000-5,200 cps at room temperature and has a low viscosity of 50-500 cps at 70 C. The composition also has an excellent curing rate for three-dimensional printing. Using the compositions, denture having a distinctive denture base and a set of artificial teeth can be manufactured via an inkjet type or digital light process type three-dimensional printing according to Computer Aided Design (CAD) data.
