SprintRay Launches Midas Restore for Same-Visit Dental Crowns

SprintRay has started shipping Midas Restore, an FDA-cleared restorative resin designed for same-visit dental restorations. The material prints crowns, inlays, onlays, and veneers directly on the Midas Digital Press, a stereolithography system built specifically for high-filler dental resins.

Why the filler content matters

Most dental resins max out around 40% to 50% filler by weight because the material still has to flow through a printer's light-curing engine. Midas Restore pushes past 75% filler, mixing glass ceramic and zirconia particles into a methacrylate base. SprintRay achieves this by forcing the viscous material from sealed capsules into the print zone, sidestepping the flow problem that limits conventional SLA and DLP printers.

The result is a restoration that meets ISO 6872 standards with a flexural strength of 215 MPa, Vickers hardness above 80 HV, and a translucency parameter of 13.5. SprintRay also claims five times the wear resistance of its earlier Ceramic Crown material and 98% gloss retention after 5,000 abrasion cycles.

Same-visit workflow

Post-curing takes four minutes. Polishing takes under two minutes. There is no glaze oven and no lab send-out. The dentist can adjust or repair the restoration intraorally before cementation. That cuts out provisionals, second appointments, and outside lab fees.

Andrew C. Johnson, DDS, MDS, CDT, FACP, Diplomate of the American Board of Prosthodontics, tested the material at OmniSmile Digital Dental Solutions. He said the combination of durability, polish retention, and straightforward finishing is what clinicians expect from a definitive restorative material.

What this means for digital dentistry

Midas Restore is part of a broader push toward chairside 3D printing that does not require trade-offs on material performance. For practices already running a Midas Digital Press, the resin is a drop-in upgrade. For labs, it represents another niche where desktop polymer 3D printing is replacing traditional subtractive milling without sacrificing mechanical properties.
