Cold polymerizable composite material for the fabrication of provisional crowns and bridges. Simple, more aesthetic, and more solid. It allows for the rapid creation of high-quality provisional crowns and bridges, as well as inlays, onlays, partial crowns, veneers, and provisional post prostheses. With Structur 3, long-lasting provisional prostheses can also be fabricated. It can also be used for relining prefabricated provisional crowns made of composite, polycarbonate, or metal. Structur 3 offers great stability, is highly aesthetic, and is easy and quick to handle. With a compressive strength of over 500 MPa and a flexural strength of 113 MPa, restorations made with Structur 3 are very aesthetic and closely resemble the definitive piece due to its natural shine and fluorescence.
