SprintRay has launched a new FDA-cleared ceramic and zirconia-filled definitive restorative resin engineered specifically and exclusively for the Midas Digital Press, a patent-pending stereolithography process that can enable the printing of up to 'three definitive crowns in ten minutes.'
Digital press stereolithography (DPS), per SprintRay, uses 'hydrodynamic principles' to create an 'environment where the viscosity of the resin is no longer a barrier to speed or accuracy.'
The new SprintRay Midas Restore material exhibits over 75% filler by weight and is said to bring glass ceramic and zirconia together in a formulation designed to ensure strength and occlusal wear resistance is optimised. It can be used to produce definitive crowns, inlays, onlays and veneers through a streamlined same-visit digital workflow.
"Traditional dental 3D printing forces a compromise: the material has to be fluid enough to print, which limits how highly filled it can be," said Amir Mansouri, CEO and Founder of SprintRay. "Midas Restore was designed in our material science lab to address that limitation. By pairing a highly filled glass ceramic and zirconia formulation with Midas Digital Press, we can give clinicians access to a new class of definitive restorative materials and bring them into an efficient same-visit workflow."
SprintRay says that, unlike restorative materials engineered primarily around maximum strength, Midas Restore was designed around how a definitive restoration polishes, wears, flexes and functions once adhesively bonded to remaining tooth structure, while maintaining the required clinical strength. The company has designed the material to arrest cracks rather than simply resist them, and its flexural modulus sits 'closer to dentin than to a glass ceramic.' Once adhesively bonded to remaining tooth structure, the restoration becomes part of a system in which material and tooth distribute function together, rather than concentrating stress at the interface.
Laboratory testing conducted by SprintRay is said to have demonstrated that Midas Restore retained 98% of its initial gloss after 5,000 simulated toothbrush abrasion cycles, and delivered five times the wear resistance of SprintRay Ceramic Crown over 200,000 cycles — wear performance comparable to a milled hybrid ceramic. In biaxial flexural testing, SprintRay says Midas Restore reached a maximum strength of 215 MPa, the highest of any SprintRay definitive restorative material. The surface hardness was measured to be greater than 80 HV, statistically equivalent to a leading nanofilled direct composite and roughly double that of previous-generation printed restorative resins. Its translucency parameter of 13.5 places it in the same range as milled lithium disilicate HT.
"We engineered Midas Restore around how a restoration actually behaves once it is bonded to a tooth, not around a single strength number," added Hossein Bassir, Chief Product Officer at SprintRay. "Filler content, polish retention, wear resistance, modulus and optics are not separate features. They are one system, and the tooth is part of it."
Per SprintRay, achieving this combination of properties requires a filler loading that conventional dental 3D printing cannot process. Its DPS technology, however, can 'actively push' viscous material into the print zone from sealed capsules, allowing Midas to work with filler loads over 75% by weight.
With the combination of Midas Restore and DPS technology, SprintRay believes it is offering a solution that facilitates same-visit dentistry. Clinicians, the company says, can press multiple units from a single capsule, post-cure in four minutes, and polish restorations to final with two wheels in under two minutes and no glaze or oven required.
"With Midas Restore, I can achieve a beautiful, lasting surface gloss in just two or three quick polishing steps with a standard polishing system," offered Andrew C. Johnson, DDS, MDS, CDT, FACP, Diplomate of the American Board of Prosthodontics and prosthodontist at OmniSmile Digital Dental Solutions, who participated in the early clinical evaluation of Midas Restore. "That combination of durability, aesthetics and straightforward finishing is what I expect as a clinician from a definitive restorative material. This is an exciting time for digital dentistry."
Midas Restore builds on the Midas Digital Press platform, introduced in 2024. Since its launch, clinicians across 33 countries have produced more than 100,000 restorations with Midas. The material will be available beginning September 1, 2026, in the United States in shades A1, A2, A3, B1 and C2. A three-pack of Single-Unit Capsules is $135 and will be available through the SprintRay Store and authorised SprintRay distribution partners. Midas Restore is validated for use with the SprintRay Midas Digital Press and SprintRay NanoCure. In the United States, it is FDA 510(k) cleared (K260661), Class II, Rx only.
