SprintRay releases Midas Restore ceramic-filled dental resin
FDA-cleared material carries more than 75% filler by weight
SprintRay has begun selling Midas Restore, a glass ceramic and zirconia-filled restorative resin aimed at definitive crowns, inlays, onlays and veneers made in a single appointment.
It carries more than 75% filler by weight, a loading SprintRay says its Digital Press Stereolithography process allows by forcing viscous material from sealed capsules into the print zone.
“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, Chief Executive Officer 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.”
Post-curing takes four minutes and polishing under two, without glaze or an oven. Restorations can be adjusted or repaired intraorally before cementation, which SprintRay says removes provisionals, second appointments and laboratory fees.
“With Midas Resto dard polishing system. 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,” said Andrew C. Johnson, DDS, MDS, CDT, FACP, Diplomate of the American Board of Prosthodontics and Prosthodontist at OmniSmile Digital Dental Solutions.
SprintRay put maximum strength at 215 MPa under ISO 6872, hardness above 80 HV, 98% gloss retention after 5,000 abrasion cycles, five times the wear resistance of its Ceramic Crown material and a translucency parameter of 13.5.
“We engineered Midas Restore around how a restoration actually behaves once it is bonded to a tooth, not around a single strength number,” said 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.”
