Here’s a look at 8 rotary instrument options to consider that will help dental technicians complete their cases.
When it comes to putting the finishing touches on your dental restoration, there are plenty of options available to lab technicians. If you do a little homework, you’ll be sure to find a polishing kit that can help you work efficiently with the materials you choose for each case. Here’s a look at 8 rotary instrument options to consider that will help you complete your cases.
General Ceramic Polishing Kit
Suitable for polishing all ceramic materials, including zirconia and glass ceramics, the General Ceramic Polishing Kit is 1 of 4 polishing tool sets available from Aidite. The kit contains emery particles for efficient polishing. The resulting polished surface is smooth, and there is no need to glaze. Other polishing sets include the Cameo Zirconia Polishing Kit, Glass Ceramic Special Polishing Set, and the Full Crown Special Polishing Set. Each kit is provided with specific recommended speeds for optimal results.
Great White Lab Series-DF 141
The Great White Lab Series-DF 141 zirconium nitride–coated lab cutters are designed to deliver increased performance and durability. The carbide burs can be used for finishing prior to veneering for both precision metal and nonprecious metal, as well as for fine adjustments with porcelain-to-metal margins. Features include 10-times increased durability and longevity, with an extremely hard cutting surface of 2800 Vickers; abrasion resistance, which reduces surface heat and vibration for a cooler, more consistent surface finish; and a comprehensive selection of shapes, sizes, and grits, manufactured with tungsten carbide heads and stainless steel shanks.
Komet USA’s lab cutters are engineered with durable, high-performance ceramic and can be used to precisely shape, trim, and carve soft acrylics, denture reline materials, and green-state zirconium dioxide. The cutters resist heat buildup and reduce clogging with their unique toothing design. Another advantage of these instruments is that they generate less vibration than traditional tungsten-carbide cutters .
This 9-piece Celtra TwisTec polishing set is optimized for zirconia-reinforced lithium silicate material and includes an assortment of high-quality instruments for optimal processing. From trimming the sprue to contouring to high-gloss polishing, this set is designed to last. The set contains 1 sintered diamond wheel (black), 3 diamond cones (flat, short, and round), 1 diamond ball (yellow), 3 diamond polisher wheels (green, violet, and yellow), 1 diamond polisher point (yellow), and directions for use. The Celtra TwisTec sets for the milling technique, and ceramic, zirconium oxide, and metal offer a practical, low-cost selection of high-quality tools for nearly every material you have to work with.
LitZir All Ceramic Finishing & Polishing
Described as a simple 3-step system for all-ceramic cases, the LitZir All Ceramic Finishing & Polishing system from Smart Dentistry Solutions Inc features reduced cleanup time with fewer components. The intuitive system is designed to deliver a familiar look and feel for lab technicians. Additionally, the company’s LitZir All Ceramic Polishing Paste can be easily applied to restorations using a felt applicator to quickly bring zirconia restorations to a high gloss before delivery.
The moment YelloStone softly touches the form of zirconia, lithium disilicate, or ceramic, freedom to contour will emerge. The rotary instrument is said to perform with a soft touch and is loaded with diamond. What makes YelloStone different is the binder that absorbs all the heat, keeping the crown cool. The YelloStone Disc is a long-lasting diamond tool that ensures a gentle and smooth grinding reduction of all-ceramic surfaces to full contour.
Specifically developed for use with zirconia and lithium disilicate restorative materials, these instruments are designed to leave a smooth surface during the contouring process. The Wagner diamond-infused spiral provides a flexing action that allows the instrument’s fingers to get into difficult occlusal areas. With the UltraBerry (coarse plus), RedBerry (coarse), BlueBerry (medium), and GoldenBerry (fine, high shine) instruments, lab technicians and clinicians can make final adjustments, refine occlusal anatomy, and create a high-shine polish.
Dura-Green DIA vitrified-bonded diamond abrasive is designed for contouring porcelains and ceramic copings. It provides enhanced performance with a smoother, chip-resistant cut vs silicon carbide or diamond burs. Densely packed diamonds are embedded throughout—from the surface to the core—in a special glass binder, offering extended cutting ability up to the last ounce of material.
