SprintRay launches resin for same-visit dental restorations

A scan can lead to a crown during one appointment: SprintRay has commercially launched Midas Restore, a ceramic- and zirconia-filled resin for definitive dental restorations. The material is intended for crowns, inlays, onlays and veneers produced through a same-visit digital workflow, rather than sent out for a separate laboratory step.

The key design choice is the resin matrix. Restorative materials are often judged by their bulk strength, but glass ceramics and zirconia are brittle and can require more tooth reduction to resist crack propagation. SprintRay says Midas Restore's matrix is designed to limit those cracks, while its flexural modulus—the material's resistance to bending—is closer to dentin. When bonded to the remaining tooth structure, the restoration and tooth can distribute loading across the bonded interface.

SprintRay's laboratory testing recorded 215 MPa of maximum biaxial flexural strength, the highest value reported among its definitive restorative materials; the reported mean was 180 MPa. Midas Restore retained 98% of its initial gloss after 5,000 simulated toothbrush abrasion cycles and showed five times the wear resistance of SprintRay Ceramic Crown over 200,000 cycles. SprintRay says that wear performance was comparable to a milled hybrid ceramic.

The formulation also creates a processing hurdle. Highly filled resins are more viscous and may not flow into a conventional print zone without assistance. SprintRay's Digital Press Stereolithography, or DPS, moves the material from sealed capsules into the print zone, supporting filler content above 75% by weight but limiting Midas Restore to the Midas Digital Press. Multiple units can be pressed from one capsule, then cured and polished without glazing or an oven.

Concretely, the benefit is a shorter path from scan to bonded restoration for clinicians who already use the Midas system, with intraoral adjustment, addition and repair possible before adhesive cementation. SprintRay says Midas Restore will be available in the United States beginning September 1, 2026, in A1, A2, A3, B1 and C2 shades; a three-pack of single-unit capsules will cost $135. The US Food and Drug Administration has cleared it as a Class II prescription-only device. SprintRay reports that the Midas platform has been used in 33 countries for more than 100,000 restorations, while early clinical evaluations of Midas Restore have so far assessed its finishing and polishing characteristics.
