A curable and radiopaque substance, a material that can be produced from same via polymerisation, a method for producing the curable substance and the cured material, and the use of the curable substance or the cured material are disclosed. The curable substance or the cured material can be used in, inter alia, orthopaedics as so-called bone cement, in particular as a tooth filling material, dental cement, dental lining material, flowable composite material (flow material) etc., as well as in diagnostic radiology. The invention also relates to the use of the curable substance generally as a construction material in an additive manufacturing process using a digital data model.

Base material arrangements having at least two layers can accommodate the addition of antifungal material (nanofiller), such as in denture base resin without significantly compromising the mechanical properties and/or translucency of the base material arrangements. Antifungal agents such as nanosilver and nanozirconia can be used to modify a surface layer of the material arrangements, such as the denture base, to overcome certain known shortcomings of the modified materials, e.g., typical acrylic resins containing nanosilver and nanozirconia.

The present invention relates to a dental composition including cement and a non-aqueous liquid, wherein the cement includes a first domain including alite, a second domain including belite, and a matrix located between one or more selected from the group consisting of the first domain and the second domain and configured to include silicon (Si)-atom-doped tricalcium aluminate (3CaO.Al.sub.2O.sub.3). A dental hydraulic composition according to the present invention is a single ointment-type composition, and is thus easy to use and exhibits a good aesthetic appearance, high curability and high biocompatibility.
