Dental Ventures of America’s Butterfly Discs are non-metallic, very flexible diamond discs designed for cutting, contouring and shaping porcelain, lithium-disilicate, or zirconia. Fabricated entirely of diamond, the DVA Butterfly Discs provide the ability to effectively cut press-able ceramic sprues, then shape & form natural contouring porcelain, lithium disilicate or other veneering materials without changing burs or discs. Butterfly Discs non-metal composition is extremely kind to the ceramic products and can be used without fear of contaminating or imparting black marks on the materials being shaped.
