摘要： A dental material comprising a pigment, wherein the pigment contains Al, Cr and one or more of Y, La and lanthanides. The dental material allows mimicking the red coloration of natural teeth and natural oral mucosa. Also provided is the use of the dental material and the pigment and starting compositions for making the pigment in the preparation of a dental restoration. Furthermore, a process for preparing a dental restoration and a process for preparing the pigment is provided.

摘要： A dental blank, having an upper surface and a lower surface, constructed of a flesh-coloured material and a tooth-coloured material. The flesh-coloured material and the tooth-coloured material are bonded together. The interface between the materials with elevations and depressions formed in or at the interface extends through an optionally curved plane, which plane is parallel to or oblique to at least part of the surfaces of the blank.

摘要： A method of determining the three-dimensional shape of a functional surface of a dental prosthesis, comprising the steps of detecting (S101) an intraoral space to generate a three-dimensional actual data set; and inputting (S102) the three-dimensional data set into a learned algorithm to generate a three-dimensional nominal data set for a functional surface of the dental prosthesis.

摘要： Radically polymerizable dental material, which includes a catalyst paste and a base paste, wherein the catalyst pastes includes an oxidizing agent, preferably a peroxide or hydroperoxide, a radically polymerizable monomer and/or oligomer with acid group and a polyfunctional radically polymerizable monomer, and the base paste comprises a polyfunctional radically polymerizable monomer without an acid group and a dihydropyridine derivative of Formula (1)




The material has good mechanical properties and does not exhibit a bitter taste.

摘要： A blank holder and a blank are provided, the blank holder having a receiving area for a substantially disc-shaped blank, the receiving area being curved. The receiving area forms a straight, circular or part-circular or arc-shaped form-fitting profile. The blank has a matching guide shell which can be inserted or turned into the form-fitting profile.
