Ceramill Sintron and Zolid FX Multilayer a Perfect Symbiosis!

Since its market launch in 2012, over three million units have been fabricated from Ceramill Sintron. More than 2,000 laboratories worldwide process CoCr in green condition. We asked four enthusiastic Ceramill Sintron users to give us insights into their daily laboratory routine with the material and furnace: how they use it, for which indications with which material combinations etc. First one – Lindauer Zahntechnik GmbH from Germany.

We manage the laboratory “Lindauer Zahntechnik GmbH“. Together with three other employees, we cover all the requirements and the entire range of prosthetic restorations. Ceramill Sintron has been an integral part of our daily practice for about three years. Initially, we mainly fabricated primary telescopes, monolithic crowns and frame- works for temporary restorations.

Digitization has made it easier to fabricate CoCr restorations in everyday dental routines. The fit is excellent and, in contrast to conventional casting, always consistent. As a result, our work flows have become more efficient and we have seen a significant increase in the cost-effectiveness of our laboratory. Meanwhile, we have specialized in wide- span bridges made of Sintron. For the bridge shown above as an example, we used Ceramill Sintron as framework material. For the monolithic crowns, we chose the super highly translucent Zolid FX Multilayer zirconia with integrated color shade gradient.

With these two materials, Ceramill Sintron and Zolid FX Multilayer, we can optimally combine stability and esthetics as well as benefit from a simple and process-safe work- flow. The preparation of the framework and the correct bonding of the zirconia crowns are crucial for restorations of this type.

The framework is covered with an opaque layer to achieve an optimal starting position for the highly translucent crowns. To condition the Zolid FX Multilayer crowns, we use Monobond Plus (Ivoclar Vivadent) and Multi-link Automix (Ivoclar Vivadent) for bonding. Then, the gingiva is applied individually with composite and polished.

From our point of view, Ceramill Sintron is the ideal framework material for this purpose as it ensures a tension-free fit and an optimal bond for the composite layering of the gingiva. In case of age-related changes of the gingiva, the composite ratio as well as the zirconia crowns can be replicated and replaced easily. Our dentists were also enthusiastic about this type of restoration, as they received a safe dental prosthesis without esthetic limitations. In future, we will increasingly offer wide-span implant-supported restorations as well as telescopic work and frameworks for temporary restorations made of Ceramill Sintron. We also regard Sintron as being an indispensable material in our laboratory in the future.
