BACKGROUND/AIM Metal-ceramic bond strength and alloys' elastic modulus clearly determine the potential of alloy application, because the ceramic integrity during mastication depends on these two characteristics. The aim of this study was to evaluate metal-ceramic bond strenght and elastic modulus of cobalt-chromium alloys in making porcelain-fused-to-metal restorations, regarding the applicatio...

PURPOSE The influence of dental alloys on MRI of the temporomandibular joint was studied using a phantom model for this joint. METHODS At 1,5 T, 15 dental alloys and 14 of their most important components were investigated acquiring sagittal (FOV: 150 mm) and transverse (FOV: 250 mm) T1-weighted SE images. In 11 cases, T1- and T2*-weighted FLASH images were measured additionally. The artifacts...

A principal requirement for biomedical alloys in device implantation is in vivo corrosion resistance, and optimal compatibility at the implant interface. In the context of materials science, biocompatibility is the ability of a material to assist a specific biological application and elicit an appropriate response, simulated in vitro or translated in vivo. The in vivo response of a device is de...

High-energy ball milling was used to prepare sets of mechanical alloys in the systems Al–Mg, Al–Mg–H, B–Mg, and Ti–B. X-ray diffraction, electron microscopy, and low-angle laser diffraction were used to characterize structures, morphology, and sizes of the alloys, respectively. The produced materials were metastable and nanocrystalline; the particle sizes were in the range of 1–501m. A constant...
