    Abstract: A dental instrument comprising a shaft and a working part adjoined thereto, with the working part having a coating in which abrasive bodies are embedded, is proposed. Firstly, the average proportion of the surface of the abrasive bodies which is covered by the coating can be at least 60%, preferably at least 65%, most preferably at least 70%. Secondly, the coating can, moreover, also consist of a nickel alloy which additionally contains at least one element selected from the group consisting of titanium, vanadium, niobium, chromium, molybdenum, tungsten, manganese, iron and cobalt. In addition, a process for coating a working part, in particular for producing a dental instrument of this type, and also the use of such a dental instrument for cutting machining of solid bodies are proposed.

    Abstract: The present invention relates to a method for producing a single-tooth replacement structure (50) or a single-tooth replacement structure (50) with a substructure (51) using a 3D printer (10) comprising at least a first applicator (A1) and a carrier (T). The method comprises the following steps: i. placing a substructure (51) on the carrier (T); ii. applying material, in particular applying a composite material (K), to the substructure (51) by means of the first applicator (A1) from a first direction (r1) relative to the substructure (51); iii. rotating the substructure (51) placed on the carrier (T) about a first axis of rotation (a) through a first angle (α) relative to the first applicator (A1); iv. applying material, in particular applying a composite material, to the substructure (51) by means of the first applicator (A1) from a second direction (r2) relative to the substructure (51); v. optionally: iteratively repeating steps iii and iv. The single-tooth replacement structure (50) is produced by means of this method. The invention also comprises a 3D printer (10) for producing a single-tooth replacement structure (50) or a single-tooth replacement structure (50) with a substructure (51), and a single-tooth replacement structure (50) or single-tooth replacement structure (50) with a substructure (51) which can be produced using said 3D printer.

    Abstract: A system for filling a root canal of a tooth and for covering pulp, with a silicone material comprising MxOy, where MxOy is selected from the group comprising CaO, BaO, MgO, Na2O, K2O, and SrO, especially preferably CaO; and/or at least one compound containing MxOy, where MxOy is selected from the group comprising CaO, BaO, MgO, Na2O, K2O, and SrO, especially preferably a compound containing CaO, in particular a compound containing CaO/SiO2. Such compositions exhibit bioactive properties and improve the ease of use and the prognosis for success of the system, according to the present invention, for filling a root canal and for covering pulp.
