Keystone Industries and Carbon Complete Validation of KeyGuide Resin for Dental Surgical Guides

GIBBSTOWN, NJ and REDWOOD CITY, CA – Keystone Industries and Carbon are pleased to announce the validation of Keystone’s KeyGuide® 3D resin for printing dental surgical guides in the Carbon® M-series printer workflow.

KeyGuide is an extremely strong Class I medical device resin that is ideal for fabricating transparent surgical guides, allowing doctors to stably place implants at a precise angle and depth. KeyGuide is manufactured in New Jersey, USA, has 3 years of guaranteed shelf life, and is available for sale in the USA, Canada, Europe, Australia, and other global territories.

The outstanding quality of KeyGuide paired with the efficient, high-quality, high-speed production of the Carbon 3D printing platform is an optimal combination for dental laboratories. With the explosion of dental implant options in the industry, the use of 3D printed surgical guides for implant planning and placement has grown exponentially – a recent study by the National Association of Dental Laboratories showed that surgical guides are among the most printed dental devices today. KeyGuide’s extreme strength and accuracy are a perfect fit for surgical guides that need to withstand the forces of drilling during surgery while remaining stable and accurate for the best patient results. Carbon users can print dozens of devices quickly and efficiently with no concerns about the quality of the printed part.

“We are really pleased to add another validated KeyPrint medical device resin to the Carbon platform,” noted Keystone Industries dental president, Ira Rosenau. “Carbon and its subscribers have been wonderful partners to Keystone since we launched KeySplint Soft Clear in 2019, including through the recent additions of both KeySplint Hard and KeyGuide to the Carbon offerings. We hope to continue to work closely with the outstanding professionals at Carbon to deliver quality and value to the subscribers with top-end products like KeyGuide.”

Carbon’s breakthroughs in oral health are powered by Carbon Digital Light Synthesis™ (Carbon DLS™) technology, which uses light and oxygen to rapidly produce high-quality, end-use products from a pool of liquid resin. Carbon’s innovations in software, hardware, and material science provide a platform for dental labs to produce next-generation, bespoke oral devices. The Carbon platform significantly improves accuracy and efficiency while reducing time to design and manufacture.

The Carbon 3D printing platform enables labs to print and post process approximately eight surgical guides in under two hours, more than 4X the typical throughput of milling processes, with a material cost per guide under $3 compared to expensive milling materials. “We’re excited we can now make the KeyGuide available to Carbon’s global network of dental partners and customers via the Carbon 3D printing platform,” said Todd Ames, Vice President of Carbon’s Oral Health Business. “We believe the KeyGuide resin will enable Carbon partner labs to provide the highest quality surgical guides with an extremely high ROI.”
