Dentsply Sirona Expands its 3D Printing Resin Portfolio

With new 3D printing resins Primeprint Splint ST and Primeprint Splint SF now Food and Drug Administration (FDA) and CE cleared, Dentsply Sirona is enhancing the range of applications for its PrimeprintSolution.

These additions to its resin portfolio allow Dentsply Sirona to answer the needs of dental professionals to fabricate patient-specific nightguards and splints for a variety of treatments that fit precisely and provide a high level of biocompatibility. Demand for these splints in dental practices is increasing, for example by patients with bruxism, according to Dentsply Sirona, the world's largest manufacturer of professional dental products and technologies.

When manufacturing these nightguards with Primeprint Solution, users experience several advantages in addition to the high degree of automation from the Dentsply Sirona 3D printing system. With a new innovative Primeprint Material Unit Type S and application specifically developed print processes, the new splint solution is said to reduce much of the manual work that would otherwise be necessary, such as time-consuming polishing. According to the manufacturer, the results are shiny after the post-curing process and can be easily detached from the support structures.

Primeprint Splint ST and Primeprint Splint SF resins allow to be printed with thin wall thickness – starting at 0.8 mm. The resins provide different degrees of hardness and flexibility and can thus be selected according to the indication and the patient’s needs. To provide optimal patient wear comfort they are free of MMA, THF-MA, and TPO2, allowing a neutral taste and scent.

Simplified Workflows with Primeprint Solution

The new resins are designed to be used in the Primeprint 3D printing system and can be used within a variety of workflows. Dental professionals have the option to handle the design themselves using inLab Software, order the design from DS Core Create, or they can order it from their preferred dental lab. When using DS Core Create design services, the splint design is provided within the turnaround time of 6 hours as a ready-to-print file, states Dentsply Sirona. This allows for immediate production, which makes it easy to delegate the workflow to staff members.

"Thanks to the new splint solution, I can now offer expanded indications for my patients with 3D printing," Meena Barsoum, DMD, a dentist from Arlington Heights, Illinois, and one of the first users of the new Primeprint Splint ST and Primeprint Splint SF resins, explains in a press release. "I love how easy it is to remove the support structures after the automated post-processing in the PPU, and my patients appreciate both the wearing comfort and the esthetics."

Max Milz, group vice president connected technology solutions at Dentsply Sirona, adds in the press release, "This innovation is another step toward advancing automated 3D printing in practices and laboratories. So dental 3D printing is once again proving to be a highly attractive technology that is particularly suitable for fabricating non-permanent removable applications such as splints, surgical guides, and models and seamlessly complements existing methods."
