Dentistry Today


SprintRay’s NightGuard Flex and NightGuard Firm 3D printing resins enable dental professionals to use the company’s frictionless ecosystem to design, print, process, and place 3D-printed flexible and rigid nightguards in-house, according to SprintRay.

These resins, now available in the United States, will enable clinicians to unlock revenue streams and cut treatment lead times for occlusal care so they can compete with direct-to-consumer offerings on convenience while delivering fully supervised care, the company said.

Thanks to its unique Cloud Design lab service and full ecosystem of 3D manufacturing products, the company said, SprintRay is uniquely positioned to help dental professionals deliver more occlusal guards to those who need them with the new materials:

  • NightGuard Flex is formulated to be the fastest, most comfortable 3D-printed nightguard in dentistry.
  • NightGuard firm is designed to produce a fast-printing splint resin with industry-leading strength and aesthetics.

“With NightGuard Flex, we’re able to provide a comfortable occlusal guard that’s easy for the dentist to deliver while being comfortable and flavorless for patient satisfaction. This material has been clinically developed from scratch to help dentists address rising occlusal issues,” said Ehsan Barjasteh, head of SprintRay resin development.

“As parafunctional habits like grinding and clenching are on the rise, our NightGuard resins will play a key role in helping doctors provide fast, cost-effective, long-term relief to thousands of patients across the world,” Barjasteh said.

NightGuard Flex becomes pliable at body temperature. It prints at twice the speed of other resins, SprintRay said, for same-day appointment delivery. It also requires fewer supports due to improved dimensional stability while in the green state, the company continued, reducing waste and improving speed to delivery. According to SprintRay, it also offers:

  • A simple chairside experience with heat-set delivery
  • Easy cleanability
  • High-impact strength and flexibility
  • Class I biocompatibility (510(k) pending)

NightGuard Firm also is designed for longevity, strength, and aesthetics with a blue tint. It is simple to clean, resists wear, and is easy to polish, SprintRay said. It prints up to 20% faster than competitive materials, the company added. It is Class I biocompatible and flavorless and odorless as well, SprintRay said.
