摘要:
Containers that are soluble in liquid methylmethacrylate and contain the PMMA powder fraction of a two-component system made up of PMMA powder component and liquid MMA monomer component are useful as components of packaging of powder/liquid two-component material, such as dental material, investment material for histology or metallography or in veterinary medicine.
摘要:
A method and a device for operating an electrical machine having separate excitation, especially a synchronous machine. With the aid of a sensor system, a variable characterizing a rotor temperature and/or a stator temperature are/is determined, and an excitation current and stator currents for the electrical machine are specified by a control unit as a function of the variable characterizing the rotor temperature and/or the stator temperature, at least in specifiable operating ranges.
摘要:
A method for automated manufacture of dentures including providing a digital data set of the individual denture to be produced, a digital separation of the model into dental arch and gingival, producing the dental arch from a ceramic or plastic material using cutting technology, producing the denture base through generative or ablative procedures from predominantly (meth-)acrylate-based plastic materials, connecting the dental arch and gingiva through bonding or joining or a combination of bonding and joining.

摘要:
For producing a mother matrix mouldof a full or partial dental prosthesis orof a temporary crown or bridgeor of a permanent crown or bridge,the data of a digitalised virtual model reflecting the status of the jaw is used to generate a data setof the digital tooth set-up of the full or partial dental prosthesis orof the temporary crown or bridge orof the permanent crown or bridge,based on which a rapid manufacturing or rapid prototyping method is used to produce a functional model of the full or partial dental prosthesis or of the temporary crown or bridge or of the permanent crown or bridge that is then invested in a curable elastic impression material from which the mother matrix mould is produced after curing the elastic impression material.

摘要:
Dental material is provided with at least one antimicrobial active substance that is applied onto inorganic particles or organic polymer beads and is bound non-covalently to the particles or polymer beads.This results in a dental material on which plaque colonisation is prevented.
