SprintRay's Midas Restore Brings Ceramic-Zirconia Dental Restorations to Chairside 3D Printing

A new class of chairside restorative material

SprintRay has started shipping Midas Restore, an FDA-cleared restorative resin filled more than 75 percent by weight with glass ceramic and zirconia. It is engineered exclusively for the Midas Digital Press, the company's high-viscosity dental 3D printing system, and is indicated for definitive crowns, inlays, onlays, and veneers completed in a single patient visit.

The launch closes a gap that has persisted in digital dentistry: most desktop 3D printers cannot move highly viscous, heavily filled resins through the print zone reliably. SprintRay addresses this with Digital Press Stereolithography, a process that pushes sealed capsules of thick material into the print area. That mechanical forcing is what allows Midas Restore to carry a filler load comparable to milled ceramics.

What the numbers mean clinically

SprintRay's internal testing reports a biaxial flexural strength of 215 MPa maximum, which the company says is the highest of any SprintRay definitive restorative material to date. Wear resistance came in five times higher than SprintRay's previous-generation Ceramic Crown material over 200,000 simulated cycles, and roughly on par with a milled hybrid ceramic. Surface hardness measured above 80 HV, which SprintRay compares to a leading nanofilled direct composite.

Gloss retention hit 98 percent after 5,000 simulated toothbrush abrasion cycles. That matters in practice: a restoration that loses surface polish quickly accumulates stains and biofilm. The translucency parameter of 13.5 places Midas Restore near milled lithium disilicate, so the finished crown or veneer matches the optical behavior of ceramic restorations produced by conventional milling.

Workflow and material behavior

The material was designed around how a bonded restoration behaves in the mouth, not around a single strength metric. Its flexural modulus sits closer to dentin than to rigid ceramic. When adhesively bonded to remaining tooth structure, the restoration and tooth distribute load together rather than concentrating stress at the interface. That is a meaningful difference for long-term margin integrity.

A single capsule can produce multiple units. Post-curing takes about four minutes. Polishing to final finish requires roughly two minutes with standard green-state zirconia or hybrid ceramic wheels. No glaze or oven firing step is needed. The material can also be adjusted, built up, or repaired intraorally before final cementation, which eliminates the provisional restoration and the second appointment most labs still require.

Market context

Midas Restore ships in the United States starting September 1, 2026, in five shades: A1, A2, A3, B1, and C2. A three-pack of single-unit capsules costs $135. The material holds FDA 510(k) clearance (K260661) as a Class II prescription-only device and is also CE marked under EU MDR as a Class IIa medical device.

SprintRay reports that clinicians across 33 countries have already produced more than 100,000 restorations on the Midas Digital Press platform since its 2024 introduction. Midas Restore extends that platform into definitive, ceramic-based restorations rather than provisional or temporary work, which is where most current chairside 3D printing resins stop short.
