The article introduces the Liquid Ceramic System MiYO, which was used for the aesthetic finalization of an implant-supported upper jaw bridge. It explains how the framework was prepared and worked on before applying MiYO color masses to color the teeth. The MiYO color masses have no masking or shading effects and can be used at any point on the tooth. Various shades and techniques are used to achieve a natural effect on the teeth and gums. The application of MiYO allows for direct visibility of the design effects and reduces the number of firing processes compared to conventional layering techniques. The article emphasizes the efficiency and aesthetic applicability of MiYO Liquid Ceramic. [Extracted from the article]

The article describes the use of VITA AKZENT LC composite paint for the customization of prosthesis bases. Previously, prosthesis bases were monochromatic, but with the light-curing paint, individual color effects can now be reproduced on composite, polymer, and hybrid ceramics. The article demonstrates, using a lip shield, how the colors are applied and what effects can be achieved. The composite paint offers a variety of possibilities to create natural color effects and can be used in various workflows. [Extracted from the article]

Common vetch (Vicia sativa L.) can be an alternative grain legume to faba beans, peas, lupins and soy beans due to its high grain protein content. As it is uncommon for grain use, cropping systems need to be developed. Weed infestation is a major problem in grain legume cultivation. Therefore, intercropping systems for common vetch which ensure a low level of weed infestation need to be designed. Thus, weed suppression of common vetch in a replacement series with spring wheat was examined in Northern Germany in the year 2018. It was the aim to define which seed density ratios will achieve the highest weed suppression, total and common vetch yield. Three harvests of crop and weed biomass and a grain harvest at full maturity were carried out in a field experiment with four replications. Weed nitrogen content was examined. Transmission of photosynthetically active radiation to weed canopy level was measured during the season. Yield and weed suppression of intercrops were analysed by different indices, and factors contributing to weed suppression were discussed. With increasing wheat ratio, weed biomass in intercrops decreased and less nitrogen was taken up by weeds. Less photosynthetically active radiation was available to weed canopy level during juvenile development in intercrops with higher wheat ratios, whereas more radiation was available to weeds in these intercrops in later stages. Higher total biomass and grain yield was achieved in intercrops compared to sole crops. The mean land equivalent ratio (LER) of all intercrops calculated from grain yield was 1.32. The index actual yield loss or gain (AYL) specified a mean actual yield gain of intercrops of 73% compared to sole crops. The competitive ratio (CR) revealed that wheat was more competitive compared to vetch. Wheat was responsible for the extra yield of intercrops. It can be concluded that common vetch can be successfully grown in intercrops with spring wheat. Effective weed suppression due to intercropping was possible when the vetch ratio was moderate. With high vetch ratios sufficient weed suppression cannot be achieved. Crop-weed competition for nitrogen and for light in the early growth stages determined weed growth in vetch-wheat intercrops.

The article discusses the challenges facing handlers and dental technicians when carrying out prosthetic reconstruction, especially of the anterior teeth. It notes that patients have high expectations of one individual and aesthetic anterior tooth restoration. It adds how highly aesthetic anterior tooth restoration made of highly translucent zirconium oxide and minimal labial scaffolding gets reduced with a nano-fluorine-apatite glass-ceramic.
