Beyond Brute Force: A New Dental Material Aims to 3D Print Enamel

LOS ANGELES, CA – September 01, 2026 – In the world of high-performance materials, the pursuit of strength often becomes an end in itself. For decades, restorative dentistry has followed this path, engineering ever-stronger ceramics to replace damaged teeth. Today, SprintRay, a key player in dental technology, introduced a product that suggests this race for pure strength may be missing the point. With the launch of Midas Restore™, a new definitive restorative material, the company is championing a different philosophy: biomimicry over brute force.

Engineered for its Midas Digital Press, the FDA-cleared resin isn't just another entry into the crowded field of dental materials. It represents a calculated bet that the future of restorations lies not in creating the most indestructible replacement, but in creating one that most closely mimics the function and feel of a natural tooth. It’s a nuanced shift, but one that could fundamentally alter the economics and patient experience of same-day dentistry.

A New Philosophy for the Digital Restoration

For years, the gold standard for crowns has been milled materials like zirconia and lithium disilicate, celebrated for their exceptional shear strength, often exceeding 900 MPa. The logic was simple: a stronger crown is less likely to break. However, this approach has its trade-offs. These ultra-hard, brittle materials are significantly stiffer than natural tooth structure, which can concentrate stress at the bond interface and, in some cases, require more aggressive reduction of the healthy tooth.

SprintRay’s Midas Restore takes a different tack. The company's internal design philosophy was captured in a simple, ambitious phrase: "If we could 3D print enamel, this is it." Instead of optimizing for a single strength number, the material was designed as a system, balancing wear resistance, polish retention, and optics to function in concert with the tooth it's bonded to.

"We engineered Midas Restore around how a restoration actually behaves once it is bonded to a tooth, not around a single strength number," explained 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."

The material’s resin matrix is designed to arrest cracks rather than simply resist them, and its flexural modulus is engineered to be closer to natural dentin than to a rigid glass ceramic. The idea is that once adhesively bonded, the restoration and the tooth distribute functional forces together, creating a more cohesive and resilient unit. This focus on biomimicry is a significant departure from the established paradigm.

The Tech That Unlocks the Material

This new philosophy is enabled by a critical technological innovation. The key to Midas Restore's properties is its high filler content—over 75% by weight—of glass ceramic and zirconia particles. This density is what provides its impressive wear resistance and lasting polish. However, such a high filler load creates a thick, highly viscous resin that is impossible for conventional 3D printers to process. Traditional systems rely on low-viscosity resins that can flow easily via gravity or capillary action into the print zone.

This is where SprintRay's proprietary Digital Press Stereolithography (DPS) technology comes in. Rather than waiting for the material to flow, the Midas Digital Press actively pushes the viscous resin into the print zone from sealed, single-use capsules. This active-force process is the breakthrough that unlocks a new class of materials.

"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."

This closed system of press and capsule is precisely why Midas Restore is exclusive to the Midas platform. It’s a vertically integrated approach that ensures the hardware is capable of handling the demands of the advanced material, turning a former limitation of 3D printing into a distinct advantage.

Redefining the Economics of the Dental Chair

The implications for dental practices are profound, promising to accelerate the shift toward truly definitive same-day dentistry. The workflow is streamlined for speed and simplicity: a clinician can press multiple restorations from a single capsule, with a crown finishing its print in under seven minutes. Post-curing takes four minutes, and the material can be polished to a final, durable gloss in under two minutes with standard wheels—no oven or complex glazing steps required.

This efficiency collapses the entire restorative process into a single appointment, eliminating the need for temporary restorations, secondary visits, and external lab bills. For the patient, this means less time in the chair and a faster resolution. For the practice, it means increased patient throughput and a potentially rapid return on investment. With material costs at $135 for a three-pack of capsules ($45 per restoration), the in-house fabrication model becomes economically compelling, especially for high-volume clinics.

The Competitive Landscape and the Road Ahead

While Midas Restore's biaxial flexural strength of 215 MPa is the highest in SprintRay’s portfolio, it remains below the figures for milled lithium disilicate (around 400-500 MPa) and zirconia. However, supporters argue this comparison is overly simplistic. The material's strength is part of a balanced profile that includes five times the wear resistance of SprintRay's previous Ceramic Crown material and a surface hardness comparable to leading direct composites.

As a new product, Midas Restore will need to build a portfolio of independent, long-term clinical data to convince skeptics accustomed to the decade-plus track records of milled materials. Yet, early feedback is promising. Dr. Andrew C. Johnson, a prosthodontist who participated in the clinical evaluation, praised its practical benefits. "With Midas Restore, I can achieve a beautiful, lasting surface gloss in just two or three quick polishing steps," he noted. "That combination of durability, aesthetics and straightforward finishing is what I expect as a clinician from a definitive restorative material."

The launch of Midas Restore is more than just a product release; it's a statement about the future direction of digital manufacturing in dentistry. By solving the viscosity problem, SprintRay has opened the door for a new generation of 3D-printed materials that can compete not just on convenience, but on a sophisticated, biomimetic approach to clinical performance.
