The Specimen Preparation Laboratory is intended for specimen preparation for all types of mechanical testing performed at the Department of Biomaterials and Oral Biology. In addition, it is also equipped with some machines for mechanical testing (EMIC) and hardness measurement with loads from 2 to 180 kg. The Laboratory makes it possible to make various types of specimens, such as those used in bond strength tests, which are usually obtained from serial cuts on the diamond blade cutter or wire cutting machine. Specimens of ceramic materials are usually produced by cutting with diamond discs and later sintering in one of the ovens intended for different types of ceramic materials. Ceramic specimens in the form of fixed partial dentures can be produced by the CAD-CAM system installed in the Laboratory, which also has a laser scanner that obtains the digital image of dental preparations. Currently, it is possible to use the press and pre-sintering furnace to produce ceramic blocks for machining in the CAD-CAM system. All specimens requiring specular surface can be polished on the semi-automatic polishing machine. The Laboratory also has an area for specimen aging through mechanical cycling (chewing simulators), thermal cycling, or storage ovens for storage of specimens in water at 37 ° C. It also has equipment for measuring the optical properties of dental materials, such as the spectrophotometer and the fluorescence meter of materials. For research on metallic materials, there is the electromagnetic induction titanium casting centrifuge and a programmable electronic casting furnace
