Komet USA recently expanded its DCB line of diamond abrasives with three yellow grinders designed to remove more substance than the original green abrasives.
Created as a complement to the line, the new versions are suitable for use on all-ceramic materials including zirconium dioxide and lithium disilicate, as well as on hard, non-precious alloys such as cobalt-chrome (CoCr), according to a press release.
The coarser configurations include the flame-shape grinder (DCB1CA); a round-cylinder shape (DCB8CA) for use on large surfaces such as crown margins; and an inverted-cone (DCB9CA) for occlusal, interdental, and basal work.
The yellow grinders are the first instruments produced through the company’s new manufacturing process, which results in an optimal bond and provides an activated surface to help ensure initial sharpness.
With interspersed diamonds on the working components, the grinders feature stable edges and shapes while providing maximal substance removal and an extended service life. Like their predecessors, the instruments allow for soft, gentle work without the need to apply pressure. After grinding, a two-step diamond-polishing procedure can be used to finish the procedure.
